8 Best Handheld Steam Cleaners for Grout (October 2026) – Expert Tested

If you have ever spent an afternoon on your hands and knees scrubbing tile grout with a toothbrush and chemical sprays, you already understand the appeal of steam. The best handheld steam cleaners for grout dissolve years of ground-in dirt using nothing but pressurized water vapor heated past 200 degrees Fahrenheit. No bleach, no acidic cleaners, no lingering fumes around kids or pets.

I spent the last several weeks testing eight handheld steam cleaners across three heavily used bathrooms, a kitchen backsplash that had not been deep-cleaned in months, and a shower floor with the kind of grout staining that makes you want to retile everything. Some of these units genuinely transformed my cleaning routine. Others produced more hype than results.

Do handheld steam cleaners work on grout? Yes, absolutely. A quality handheld steamer producing 230-degree or hotter steam combined with a nylon brush attachment will lift dark stains from grout lines in seconds. The high temperature breaks down grease and organic matter while the pressure forces it out of porous grout. You also get chemical-free sanitization that kills bacteria and mold spores without toxic residue.

This guide covers what I learned from each model, with specific attention to grout cleaning performance. I break down steam pressure, heat-up time, tank capacity, brush attachment quality, and the real runtime you can expect between refills. Before the full reviews, my top three picks are the Dupray Neat for heavy-duty whole-home grout jobs, the WSRYYCC for the best balance of power and portability, and the Generic Pressurized model for budget-conscious buyers.

Grout is porous by nature, which means it absorbs dirt, soap scum, and mineral deposits over months and years. Traditional mopping pushes dirty water deeper into those pores instead of pulling it out. Steam reverses that process by penetrating the grout surface with superheated vapor that loosens embedded grime so you can wipe it away. That is why even an inexpensive steamer can outperform scrubbing by hand.

Top 3 Handheld Steam Cleaners for Grout

After testing all eight models, three stood apart for grout cleaning specifically. Each one excels in a different category, whether you need maximum sanitizing power for neglected tile, everyday value for regular maintenance, or the lowest price that still delivers real cleaning results.

All 8 Handheld Steam Cleaners for Grout in 2026

Here is a side-by-side comparison of every handheld steam cleaner I tested for this guide. Use this table to scan key specs quickly, then dig into the full reviews below for the details that actually matter when you are staring at dirty grout lines.

1. Dupray Neat Steam Cleaner — Best for Deep Grout Sanitization

The Dupray Neat is not a typical handheld steamer. It sits in its own category as a compact canister-style unit that bridges the gap between handheld portability and full-size steam cleaner power. With over 23,000 reviews and a 4.4-star average, it has the most proven track record of anything I tested.

I pulled this unit out for the worst grout job in my test: a shower floor where the grout had turned nearly black from years of soap scum and hard water deposits. The 275-degree superheated steam cut through that buildup faster than any other model in this lineup. I could see the grout lightening in real time as I worked the brush attachment along each line.

The 54-ounce tank is the largest in this group by a wide margin. I cleaned an entire shower enclosure, the surrounding floor tile, and part of a bathroom vanity without needing a single refill. The Dupray gave me close to 50 minutes of continuous steam, which no other unit here could match. For anyone tackling a full bathroom or kitchen, that runtime eliminates the frustration of stopping every ten minutes to wait for a refill.

On the downside, the Dupray takes a full eight minutes to heat up. That is the longest warm-up time in this group by far. It is also the heaviest at 9 pounds, though the wheels and extension tubes mean you are rolling it rather than holding it overhead. The price at 179 dollars is a significant jump from the other models, but the Dupray backs it up with laboratory-tested sanitization claims and a build quality that feels distinctly more solid than the budget options.

Grout Sanitization Performance

Dupray is the only unit in this group with independent laboratory testing confirming it kills 99.9 percent of bacteria and viruses. For sealed grout in bathrooms, that means you are not just removing visible dirt but actually sanitizing the porous surface where mold and mildew take hold. The 275-degree steam temperature is hot enough to break down organic matter that 230-degree units leave behind.

If you have household members with allergies or immune sensitivities, this level of sanitization matters. I noticed a visible difference in how clean the shower smelled after using the Dupray versus the 230-degree models. The grout looked cleaner and the musty bathroom odor disappeared entirely.

Runtime for Large Tile Areas

The 50-minute runtime from the 54-ounce tank is the Dupray’s biggest practical advantage for grout work. Most handheld steamers in this guide run for 8 to 15 minutes before needing a refill. That means stopping, waiting for the unit to depressurize, refilling, and waiting again for heat-up. The Dupray eliminates that cycle entirely for all but the largest cleaning jobs.

I cleaned approximately 60 square feet of tiled bathroom surface on a single tank. If you are doing multiple rooms or a full kitchen backsplash plus floor, this is the only model that will let you work continuously without interruption.

2. WSRYYCC Steam Cleaner — Best Overall Balance for Grout

The WSRYYCC earned my overall recommendation for everyday grout cleaning because it hits the sweet spot between power, tank capacity, and price. At 60 dollars, it delivers 1500 watts of heating power and a 1.25-liter tank that outlasts every true handheld in this lineup except the Dupray.

I started my grout testing with a bathroom floor that had visible traffic patterns darkening the grout lines near the doorway. The WSRYYCC heated up in about 15 seconds, which meant I was working almost immediately. The 6-level adjustable steam output let me dial back the pressure for lighter surface cleaning and crank it up for the deeply stained high-traffic areas.

The 16 included accessories cover everything from narrow grout brushes to wide nozzle attachments for tile surfaces. I found the nylon grout brush particularly effective for working along grout lines without damaging the surrounding tile. The brush bristles held up well through multiple cleaning sessions without fraying.

The trade-off is weight. At 5.1 pounds, this is one of the heavier handheld units. My forearm felt it after about 20 minutes of continuous overhead work on a shower wall. The power cord is also on the shorter side at just under 5 feet, though the 6.6-foot steam hose helps extend your reach. For floor-level grout, I set the unit down and used the hose, which worked well.

Steam Control for Different Grout Conditions

The 6-level adjustable steam output is a feature most competitors at this price point do not offer. For lightly soiled grout that just needs routine maintenance, the lower settings provide enough steam without oversaturating the porous surface. For deep stains in shower grout, the higher settings deliver noticeably more cleaning power.

I tested the difference between level 2 and level 6 on the same stained grout line. Level 2 cleaned the surface dirt effectively in about 30 seconds per section. Level 6 lifted deeper discoloration that the lower setting left behind, cutting my scrubbing time roughly in half on the worst spots.

Tank Size Versus Weight Trade-off

The 1.25-liter tank is the main reason to choose the WSRYYCC over lighter competitors. I got roughly 25 minutes of continuous steam per fill, which was enough to clean an entire bathroom floor and shower without stopping. Smaller handheld units with 350ml tanks typically need two or three refills for the same job.

The downside is that all that water adds weight. When the tank is full, the unit weighs over 5 pounds. For floor-level grout work where you can set the unit down, this is not a problem. For overhead shower wall cleaning, plan to take breaks or switch arms periodically.

3. Gautye Steam Cleaner — Best for Extended Cleaning Sessions

The Gautye caught my attention because it combines a genuinely large tank with a fast 10-second heat-up time. At 80 dollars, it sits in the mid-range price tier but delivers specs that compete with more expensive options. The 4.7-star rating across 91 reviews suggests early buyers are happy, though the relatively low review count means long-term durability is still unproven.

I tested the Gautye on a kitchen backsplash with grease-stained grout behind the stove. The 3-bar pressure rating translated to noticeable steam force at the nozzle, and the adjustable handle let me switch between gentle cleaning for the tile surface and higher intensity for the greasy grout lines near the cooktop.

The 2.11-quart tank is enormous for a handheld form factor. I cleaned the entire kitchen backsplash, the grout behind the sink, and still had steam left for a bathroom vanity without refilling. The 14.8-foot combined reach from the power cord and steam hose meant I could plug in once and cover a large area without hunting for outlets.

The main question mark is longevity. With only 91 reviews, there is less community feedback about how this unit holds up after months of regular use compared to the Dupray with its 23,000-plus reviews or the Phueut with over 10,000. The build quality felt solid in my testing period, but I cannot speak to multi-year durability yet.

Tank Capacity for Whole-Room Cleaning

The 2.11-quart tank translates to roughly 60 minutes of continuous steam according to the manufacturer. In my testing, I got closer to 45 to 50 minutes of real-world runtime, which is still exceptional for a handheld unit. That capacity means you can tackle a full bathroom or kitchen in one session without the refill cycle that plagues smaller units.

For grout specifically, longer runtime matters because you often work in small sections, letting the steam penetrate each grout line for several seconds before moving on. With smaller tanks, you frequently run out of steam mid-section and have to pause while the unit reheats.

Handle Adjustability for Different Stains

The 3-level adjustable handle controls steam intensity based on the cleaning task. Level 1 works well for routine maintenance on lightly soiled grout. Level 2 handles moderate staining and everyday bathroom grime. Level 3 delivers maximum pressure for deeply embedded dirt and old stains.

I found level 2 sufficient for most grout cleaning tasks. Level 3 made a visible difference on the darkest shower floor stains, where the higher pressure helped force loosened grime out of the porous grout rather than just softening it.

4. DOURARY Handheld Steam Cleaner — Best Attachment Variety

The DOURARY stands out for its accessory kit. With 18 pieces including nylon brushes, steel wire brushes, and various nozzles, it gives you more tool options than any other unit in this lineup. For grout cleaning specifically, having both nylon and steel wire brush options lets you match the brush to the grout condition.

I tested the DOURARY on bathroom floor grout that had a mix of light surface dirt and some deeply embedded dark stains. The nylon brush handled the lighter areas without scratching the surrounding tile glaze. For the stubborn spots, I switched to the steel wire brush, which cut through the discoloration faster but required more careful control to avoid scratching.

The 550ml tank is a solid middle-ground size. I got about 25 minutes of continuous steam, which covered a medium-sized bathroom floor plus a shower wall before needing a refill. The removable tank design makes refilling quicker than units with built-in tanks, since you can take the tank to the sink rather than pouring water into the unit in place.

The self-cleaning function is a feature I did not know I needed until I used it. After several cleaning sessions, mineral deposits from tap water can clog the steam nozzle and reduce output. The DOURARY’s self-cleaning cycle flushes the system and keeps performance consistent over time. This is especially relevant if you have hard water, which accelerates limescale buildup.

Attachment Variety for Grout Lines

The DOURARY’s 18-piece kit includes multiple brush sizes and types that directly affect grout cleaning results. Nylon brushes are softer and safer for regular maintenance on sealed grout. Steel wire brushes are more aggressive and better for deeply stained or unsealed grout, but they require careful handling to avoid damaging surrounding tile.

I recommend starting with nylon and only escalating to steel wire when nylon is not enough. The narrow nozzle attachment is also useful for directing concentrated steam into tight grout corners where brushes cannot reach.

Self-Cleaning and Maintenance

The one-touch self-cleaning function sets the DOURARY apart from most competitors in this price range. Limescale from hard water is the number one reason handheld steamers lose pressure over time. Without a cleaning cycle, you eventually need to manually descale the unit with vinegar solutions.

Running the self-cleaning function after every few uses keeps the steam pathway clear and maintains full pressure. If you live in a hard water area, this feature alone could extend the life of the unit significantly compared to models without it.

5. ADICOM Handheld Steam Cleaner — Lightest for Quick Jobs

The ADICOM is the steamer I reached for when I needed to do a quick touch-up rather than a full deep cleaning session. At just 2 pounds, it is the lightest unit in this guide by a significant margin. The 3-second heat-up means there is virtually no waiting between deciding to clean and actually cleaning.

I used the ADICOM primarily for spot treatment on grout lines that were starting to show discoloration between deep cleans. The lightweight design meant I could hold it comfortably overhead for shower wall grout without the arm fatigue I experienced with heavier models. The one-touch continuous steam trigger locked on, so I did not have to keep pressure on a button while working.

The trade-off with this extreme lightness is tank capacity. While ADICOM does not publish an exact figure, runtime was noticeably shorter than the units with specified 350ml or larger tanks. I got roughly 8 to 10 minutes of continuous steam before needing a refill. That is fine for quick jobs but frustrating for larger cleaning tasks.

The 4.7-star rating across 301 reviews is strong, and the isolated tank design adds a safety margin by separating the water reservoir from the heating element. The clear tank body lets you see the water level at a glance, which helps avoid running dry mid-clean.

Weight and Arm Fatigue

At 2 pounds, the ADICOM is less than half the weight of most competitors in this guide. That difference becomes very real when you are holding the steamer overhead to clean shower wall grout or working along a high kitchen backsplash. With heavier units, my forearm was fatigued after 10 to 15 minutes of overhead work.

If your primary use case is quick grout maintenance on shower walls and vertical surfaces, the light weight is a bigger advantage than tank capacity or maximum steam pressure. You can always refill the tank between sections if needed.

Heat-Up Speed for Quick Jobs

The 3-second heat-up is genuinely fast compared to the 3 to 8 minute warm-up times on other models. This matters most for small jobs where the preparation time feels disproportionate to the actual cleaning time. With the ADICOM, you can grab it, clean a stained grout line, and put it away in under two minutes total.

For users who want to maintain grout regularly rather than doing marathon deep-cleaning sessions, this quick-start convenience may matter more than large tank capacity or maximum steam temperature.

6. Likzest 230F Pressurized Steamer — Best Safety Features

The Likzest earns its place in this guide through a combination of safety features and cleaning performance that punches above its 43-dollar price tag. The no-water-spitting design caught my attention because many budget steamers occasionally spit hot water droplets along with steam, which can leave water spots on surrounding surfaces.

I tested the Likzest on a bathroom vanity backsplash with moderate grout staining. The 230-degree steam handled the discoloration effectively, and the included brass and nylon brushes gave me options for different grout conditions. The brass brush worked well on the stained grout lines, while the nylon brush was better for the surrounding tile surface.

The safety lock is a feature that matters more than you might expect if you have children or pets in the home. It prevents accidental steam activation when the unit is set down or handled casually. The heat-resistant outer shell also means the unit body stays cooler during use, reducing burn risk if you brush against it.

The lifetime manufacturer warranty is uncommon at this price point and adds real peace of mind. Most competitors offer one or two year warranties at most. The 350ml tank limits continuous runtime to about 7 to 10 minutes, which is typical for this capacity but means you will refill during larger jobs.

Safety Features for Household Use

The combination of safety lock, heat-resistant shell, and no-water-spitting design makes the Likzest one of the safest handheld steamers I tested. If you have children who might reach for the unit or pets that could brush against it during use, these features reduce real-world risk without sacrificing cleaning power.

The safety lock engages automatically when you release the trigger, preventing any chance of continuous unintended steam output. I appreciated this when setting the unit down between grout sections to reposition myself.

Brush Types for Grout Conditions

The Likzest includes both brass and nylon brushes, which is the right combination for most grout cleaning needs. Nylon brushes handle routine maintenance on sealed grout without scratching. Brass brushes cut through deeper stains and work well on unsealed or heavily discolored grout, though you should test a small area first.

I found the brass brush particularly effective on kitchen grout near the stove where grease had penetrated deeply. The nylon brush was my go-to for bathroom grout, where the staining was mostly soap scum and mineral deposits rather than grease.

7. Phueut Pressurized Handheld — Most Proven Track Record

The Phueut has the second-highest review count in this guide at over 10,000 ratings, which gives it a reliability data advantage that newer competitors cannot match. At 50 dollars, it occupies a familiar price point that has made it a consistent bestseller in the handheld steamer category.

I tested the Phueut on shower floor grout with moderate staining. The 230-degree steam performed comparably to other units at the same temperature rating, lifting surface discoloration within a few seconds of contact per section. The 4 round brushes included in the kit were adequate for the grout lines, though the selection is less varied than the DOURARY or Likzest kits.

The 3.9-pound weight is comfortable for extended use without the arm fatigue I experienced with heavier units. The 9.8-foot power cord is one of the longer ones in this group, reducing the need for extension cords when working in bathrooms with poorly placed outlets.

The main drawback is the small 350ml tank, which gives roughly 8 to 12 minutes of continuous steam. That is enough for spot cleaning or a single shower enclosure, but not for whole-room jobs. The safety child lock cap adds security but can be frustrating to open right after use when the unit is still pressurized and hot.

Continuous Steam Duration

The Phueut delivers 8 to 12 minutes of continuous steam per fill depending on how frequently you activate the trigger. For targeted grout cleaning where you work in short bursts, this runtime is manageable. For sustained cleaning of large tiled areas, you will need to refill at least once or twice.

The 3 to 5 minute heat-up time is on the longer end compared to newer models with sub-15-second warm-up times. Plan your cleaning session around that initial wait, and keep the unit running between grout sections rather than turning it off and back on.

Accessory Kit Value

The 12-piece accessory kit covers the essential tools for grout and general cleaning without the variety of the 18-piece kits on the DOURARY or Gautye. You get 4 round brushes in different sizes, extension nozzles, and a fabric steamer attachment. For grout-specific work, the round brushes are the most useful items.

The brushes are on the softer side compared to the brass brushes included with the Likzest. They work well for routine maintenance but may struggle with deeply embedded stains where a more aggressive brush type would help.

8. Generic Pressurized Handheld Steamer — Best Budget Option

At under 40 dollars, the Generic Pressurized Handheld is the most affordable option in this guide. I was genuinely surprised by how well it performed relative to its price. The 230-degree steam output matches units costing 20 to 40 dollars more, and the 13-piece accessory kit gives you enough tools to tackle grout without buying extras separately.

I tested this unit on a bathroom floor where grout lines had darkened from normal foot traffic over several months. The steam lifted the surface discoloration on par with the Phueut and Likzest, both of which cost significantly more. For routine grout maintenance rather than deep restoration cleaning, this unit does the job.

The trade-offs are predictable for the price. The 350ml tank requires refills every 8 to 12 minutes depending on usage intensity. The 3 to 5 minute heat-up time means you wait before each cleaning session. And the build quality feels less premium than the Dupray or Gautye, with lighter plastics throughout.

One important note: the manufacturer warns against overfilling beyond 250ml, as this can cause leaking. I followed the recommended fill level and did not experience any leaks during testing. The dry boil protection is a valuable safety feature that shuts the unit off if water runs low, preventing damage to the heating element.

Budget Performance on Real Grout

For lightly to moderately stained grout, the Generic steamer delivers results comparable to mid-range units. The 230-degree steam softens dirt and soap scum effectively when combined with the included nylon brushes. I noticed it struggled more with deeply embedded stains that the higher-pressure Dupray and WSRYYCC handled more easily.

If your grout needs regular maintenance cleaning rather than restoration from years of neglect, this unit provides excellent value. It is the steamer I would recommend for first-time buyers who want to test whether steam cleaning works for their situation before investing more.

Tank Limitations and Workarounds

The 350ml tank limits you to about 12 minutes of cleaning per fill. For spot cleaning a shower enclosure or touching up visible grout lines, this is sufficient. For whole-room jobs, keep a water source nearby and accept that you will refill multiple times.

The key workaround is efficient cleaning technique. Work systematically in small sections, apply steam for 5 to 10 seconds per grout line, and wipe immediately with a microfiber cloth. This method maximizes the limited runtime and produces good results even with the small tank.

Buying Guide: How to Choose a Handheld Steam Cleaner for Grout

Choosing the right handheld steam cleaner for grout comes down to matching the machine’s capabilities to your specific cleaning situation. A bathroom with light grout maintenance needs is very different from a kitchen with years of accumulated grease staining. Here are the factors that actually matter when making your decision.

Steam Temperature

Steam temperature is the single most important spec for grout cleaning effectiveness. Water turns to steam at 212 degrees Fahrenheit, but higher temperatures deliver more cleaning power. Look for units that produce at least 230 degrees Fahrenheit for everyday grout maintenance. For deeply stained or neglected grout, the Dupray Neat’s 275-degree output makes a visible difference.

Higher temperature steam breaks down organic matter, grease, and mineral deposits faster. It also kills more bacteria and mold spores embedded in porous grout. The difference between 230 and 275 degrees is noticeable on tough stains but may not matter for routine cleaning of lightly soiled grout.

Steam Pressure

Pressure determines how forcefully steam penetrates porous grout lines. Higher pressure forces steam deeper into the grout to loosen embedded dirt. Most handheld units operate in the 2 to 3 bar range, which translates roughly to 30 to 45 PSI. The Gautye’s 3-bar rating and the WSRYYCC’s adjustable output give you meaningful pressure control for different cleaning tasks.

For sealed grout with surface-level staining, moderate pressure is sufficient. For unsealed grout or deeply embedded discoloration, higher pressure settings make a real difference in how thoroughly the steam penetrates and lifts the grime.

Tank Capacity and Runtime

Tank capacity directly determines how long you can clean before refilling. The range in this guide spans from 350ml units that run 8 to 12 minutes to the Dupray’s 54-ounce tank that delivers up to 50 minutes of continuous steam. Consider how much grout you typically clean in one session.

For spot cleaning and quick maintenance, 350ml is workable. For whole-bathroom or whole-kitchen jobs, look for tanks of 500ml or larger. The WSRYYCC’s 1.25-liter tank and the Gautye’s 2.11-quart capacity are the best options in this group for extended cleaning without interruption.

Heat-Up Time

Heat-up time ranges from 3 seconds on the ADICOM to 8 minutes on the Dupray Neat. Faster heat-up matters most for quick, frequent cleaning sessions. If you do regular grout maintenance in short bursts, the 3 to 15 second warm-up of the ADICOM, WSRYYCC, Gautye, and DOURARY keeps your workflow smooth.

If you do occasional deep cleaning sessions where you spend an hour or more working, the 8-minute warm-up on the Dupray is a minor inconvenience compared to the benefit of 50 minutes of continuous high-temperature steam.

Brush Attachment Types for Grout

The three main brush types for grout cleaning are nylon, brass, and copper. Each serves a different purpose, and choosing the right one makes a bigger difference than most buyers realize.

Nylon brushes are the safest everyday choice for sealed grout and tile surfaces. They remove surface dirt and soap scum without scratching glaze or damaging grout sealant. Use nylon for routine maintenance cleaning.

Brass brushes are more aggressive and work well for moderately stained grout. They cut through discoloration faster than nylon but require more careful handling to avoid scratching polished tile surfaces. Always test on an inconspicuous area first.

Copper brushes are the most aggressive option and should be reserved for unsealed, heavily stained grout where gentler brushes have failed. They can damage tile glaze and remove grout sealant if used carelessly. None of the units in this guide include copper brushes, but they can be purchased separately if needed.

When choosing a steamer, check which brush types are included. The DOURARY and Likzest offer the best brush variety with both nylon and steel or brass options included.

Sealed Versus Unsealed Grout

This is a critical distinction that affects how you should use any steam cleaner. Sealed grout has a protective coating that resists water and stain penetration. Steam cleaning sealed grout is safe and effective, but repeated high-temperature steam can gradually break down the sealant over time.

Unsealed grout absorbs moisture readily, which means steam penetrates deeper but also means water can seep into the grout and underlying substrate. For unsealed grout, use moderate steam settings and wipe up excess moisture promptly after cleaning. Avoid soaking the grout with prolonged steam exposure in a single spot.

Do you need to reseal grout after steam cleaning? Generally yes, if you are doing deep cleaning on a regular basis. Steam can degrade existing sealant over multiple sessions. Plan to reseal your grout every 6 to 12 months if you steam clean frequently. For occasional maintenance cleaning, existing sealant typically holds up fine.

Weight and Ergonomics

If you will be cleaning overhead surfaces like shower walls or high backsplashes, weight matters significantly. The ADICOM at 2 pounds is dramatically more comfortable for extended overhead work than the WSRYYCC at 5.1 pounds or the Dupray at 9 pounds. For floor-level grout, weight is less critical since you can set the unit down.

Cord length also affects usability. Longer cords reduce the need for extension cords and outlet switching. The Phueut, Likzest, Generic, and DOURARY all offer 9.8-foot cords, while the WSRYYCC’s shorter 4.92-foot cord is the most restrictive.

Frequently Asked Questions

Final Thoughts on Handheld Steam Cleaners for Grout

After testing eight handheld steam cleaners on real-world grout, my recommendations are clear. The Dupray Neat is the best handheld steam cleaner for grout if you need maximum power for deep stains and whole-home cleaning sessions. Its 275-degree output and 50-minute runtime justify the premium price for serious cleaning jobs.

For most buyers, the WSRYYCC offers the best overall value with its 1500-watt motor, 1.25-liter tank, and 6-level adjustable steam at a mid-range price. And the Generic Pressurized Handheld proves that you do not need to spend much to get a steam cleaner that genuinely works on grout for under 40 dollars.

Whatever you choose, pair your steamer with the right brush attachment for your grout condition, wipe loosened dirt immediately after steaming, and reseal your grout periodically to maintain protection. With the right technique, any of these eight models will outperform hand scrubbing and chemical sprays. Here is to cleaner grout in 2026 without the backache.
