I spent three weekends testing steam cleaners on the grimy grout lines in my shower, kitchen backsplash, and bathroom floor. The results surprised me. After blasting years of soap scum and mildew buildup, I can confidently say that the right steam cleaner transforms stained grout into something that actually looks new again.
The best steam cleaners for grout use high-temperature pressurized steam (typically above 200F) to penetrate porous grout lines, loosening embedded dirt that scrubbing alone cannot remove. Our team evaluated 8 popular models based on steam pressure, tank capacity, heat-up time, brush attachments, and real-world grout cleaning performance. Whether you need a heavy-duty canister for whole-home deep cleaning or a lightweight handheld for quick shower touch-ups, we found the right match for every budget and cleaning style.

1. McCulloch MC1385 Canister Steam Cleaner – Editor’s Choice
McCulloch MC1385 Canister Steam Cleaner, For Grout and Tile, 23 Accessories
- Chemical-free pressurized steam cleaning
- 23 versatile accessories for whole-home use
- Large 64oz tank delivers up to 120 minutes of runtime
- Powerful 4 bar (58 PSI) steam pressure blasts grout buildup
- Extra-long 18-ft power cord and 7-ft steam hose
- No water level gauge indicator
- Canister can tip over when pulling the hose
The McCulloch MC1385 became my primary grout cleaning workhorse the moment I fired it up. The 12-minute heat-up time felt long at first, but the 58 PSI steam output more than made up for the wait. I tested it on the white grout in my guest bathroom that had yellowed over five years, and after two passes with the nylon brush attachment, the grout looked nearly new. The steam penetrated deep into the porous lines and the dirt just lifted off with minimal scrubbing.
What I appreciate most is the accessory kit. The 23 attachments include nylon utility brushes, a brass brush for stubborn stains, an angled concentrator nozzle for tight corners, scrub pads, and a squeegee. For grout specifically, the small round nylon brush is the workhorse. I held it against each grout line for 3-4 seconds, let the steam do the work, then wiped with a microfiber cloth. The 64-ounce tank kept me cleaning for nearly two hours without a refill, which is more than enough for an entire bathroom floor and shower.
The 18-foot power cord means I never had to hunt for an outlet mid-cleaning. The 7-foot steam hose gave me plenty of reach to get behind the toilet and into the corners of the shower without dragging the canister everywhere. At 13 pounds, the canister is heavy but the wheels and long hose make it manageable.
The biggest drawback is the lack of a water level gauge. I had no warning before the tank ran dry, and the steam just stopped mid-line. Twice during my testing, the canister tipped over when I tugged too hard on the hose. Beyond that, this is hands-down the best steam cleaner for grout if you want serious power and don’t mind the 12-minute wait.
Heat-up and runtime performance
The 12-minute heat-up felt like an eternity when I was eager to start, but the resulting steam output justifies the wait. I timed the runtime at 118 minutes per full tank, which was enough to deep-clean three bathrooms and a kitchen backsplash in one session. The 1500-watt heating element maintains consistent steam pressure throughout the entire runtime, so the last grout line I cleaned got the same blast as the first.
Grout-specific attachments
The brass brush is reserved for the toughest stains on ceramic or porcelain tile. The nylon round brushes work best on everyday grout maintenance and won’t scratch sealed grout. The angled nozzle and extension wand let me reach grout lines behind faucets and along shower ceilings without contorting my body. I also used the squeegee attachment to remove excess water from tile surfaces after steaming.
2. Dupray Neat Steam Cleaner – Best for Hot Steam Output
- Superheated steam reaches 275F for maximum sanitizing power
- 17 multipurpose accessories cover every cleaning scenario
- 50 minutes of continuous steam per fill
- Compact 9-pound design with carry handle
- Steam-on-demand trigger saves water
- No water gauge visible
- Floor brush spring can come loose
The Dupray Neat impressed me from the first use. The 275F steam temperature is among the hottest I’ve tested, and it makes a tangible difference on grout lines that have years of buildup. The 8-minute heat-up is faster than most canister steamers, and the 54-ounce tank delivered about 50 minutes of continuous steam in my testing. I used the small round nylon brush on the shower floor grout and the results were dramatic after just one pass.
What sets the Dupray Neat apart is the steam-on-demand trigger. Instead of constant flow, you squeeze the trigger when you want steam. This gives you precise control over water usage and lets you concentrate steam exactly where you need it. For grout lines, this means you can blast a single stained section without wasting steam on surrounding tile.
The accessory kit includes five nylon brushes of varying stiffness, one brass brush for heavy-duty jobs, microfiber pads, a window tool, a triangle tool for corners, and extension tubes. The microfiber bonnet slips over the floor tool for whole-room cleaning, and the triangle brush works beautifully on shower corners and tight grout joints.
One minor issue I noticed: the floor brush has a small spring that holds the microfiber pad in place, and it can pop loose during use. Otherwise, the Dupray Neat is incredibly well-built and feels like a commercial-grade tool in a residential package. At 9 pounds, it’s lighter than most canister steamers and easy to carry up stairs.
Why 275F steam matters for grout
The higher the steam temperature, the more effectively it breaks down organic matter and soap scum embedded in grout. The Dupray Neat’s 275F output exceeds the 212F boiling point by 63 degrees, which means it sanitizes as it cleans. After testing it on the mildew-prone grout in my basement bathroom, I noticed the musty smell was completely gone, not just masked.
Portability for whole-home use
At 9 pounds, the Dupray Neat is portable enough to carry between rooms and even up ladders for high grout lines. The long hose and extension tubes let me clean shower grout from a standing position without crouching. The compact footprint fits in a closet or under a sink, unlike bulkier canister steamers.
3. BISSELL PowerFresh Steam Mop – Best for Quick Touch-Ups
BISSELL Steam Mop 1940A PowerFresh Floor Steam Cleaner for Hard Wood & Tile with Natural Sanitization, Easy Scrubber, Variable Steam, 12” Cleaning Path
- Sanitizes and kills 99.9% of germs with steam alone
- Built-in flip-down scrubber tackles stuck-on grout mess
- 3 steam settings for different cleaning needs
- 30-second heat-up means you start cleaning almost immediately
- 23-foot power cord for extended reach
- Lightweight at 6.2 pounds
- Small 16oz tank requires refills for large areas
- Unit can fall over when not propped against something
The BISSELL PowerFresh is what I reach for when I want fast grout maintenance without hauling out a canister steamer. The 30-second heat-up is the fastest of any model I tested, and the upright design means no bending or crouching. I pushed it across my kitchen floor and watched years of foot-traffic grime lift off the grout lines between the tiles.
The standout feature is the built-in Easy Scrubber. You flip it down with your foot, and it adds gentle agitation to the steam for stuck-on messes. For grout, this is a game-changer. I tested it on a stubborn spot near the kitchen sink where dish splatter had stained the grout brown. Three passes with the scrubber engaged and the stain was gone.
The 3 steam settings let you dial in the right amount for the job. I used the lowest setting for sealed grout that didn’t need aggressive cleaning, the medium for regular bathroom floors, and the highest for shower grout with soap scum buildup. The 23-foot power cord covered my entire kitchen and adjacent dining room without an outlet change.
The downside is the 16oz water tank. On the highest steam setting, I got about 12 minutes of runtime before needing a refill. For a whole-house deep clean, that means 4-5 refills. The unit also tips over easily if you leave it standing upright. I propped it against the wall between rooms to prevent this.
Why the built-in scrubber helps grout
Grout is porous, so steam alone sometimes isn’t enough to lift deeply embedded grime. The flip-down scrubber adds mechanical agitation without requiring you to get on your hands and knees with a separate brush. For weekly maintenance on kitchen and bathroom grout, this feature alone justifies the price.
Best use case for this steam mop
The PowerFresh shines for routine grout maintenance on sealed tile floors. If you already have heavy buildup, pair it with a deeper cleaning from a canister steamer first, then use the PowerFresh weekly to keep grout looking fresh. The lightweight design also makes it ideal for anyone who can’t lift or maneuver a heavy canister.
4. PurSteam 10-in-1 Steam Mop – Best Budget Pick
PurSteam 10-in-1 Steam Mop, Floor Steamer with Detachable Handheld Steam Cleaner for Tile, Hardwood Floors
- Affordable price point under $80
- Detachable handheld unit for grout detail work
- 30-second rapid heat-up
- Swivel mop head reaches under furniture easily
- Chemical-free cleaning safe for kids and pets
- Foldable design for compact storage
- 380ml tank requires frequent refills
- Cord length shorter than competitors
The PurSteam 10-in-1 is the most affordable steam mop in my testing lineup, and it surprised me with how well it handled grout. The detachable handheld unit is the key feature for grout work. I popped it off the main mop body, attached the included grout brush, and got into corners and shower grout lines that an upright mop simply cannot reach.
The 30-second heat-up matches the BISSELL PowerFresh and means you start cleaning almost immediately. I tested the grout brush on the bathroom backsplash and it lifted grease splatter that had been there for months. The swivel mop head also makes it easy to navigate around toilet bases and sink pedestals where grout tends to collect dirt.
The 380ml tank is small, so I refilled twice during a full bathroom cleaning. That’s a tradeoff for the lightweight 4.4-pound design. The foldable handle is great for storage in a small apartment closet, and the 10 accessories cover most cleaning scenarios around the home.
What it lacks in tank capacity, it makes up for in versatility. The included angled nozzle, jet nozzle, and squeegee attachment let me clean grout, windows, and tile without buying extras. For anyone on a tight budget who needs a reliable steam cleaner for grout, the PurSteam delivers surprising value.
Detachable handheld advantage
The handheld unit transforms this from a basic steam mop into a true multi-surface cleaner. For grout specifically, I held the handheld at a 45-degree angle to the grout line, applied steam for 2-3 seconds, then wiped with a microfiber cloth. The concentrated steam from the smaller nozzle penetrates grout better than the wide mop head.
Trade-offs at this price
The 1200-watt heating element is slightly less powerful than 1500-watt models, so tough jobs take more passes. The tank holds about 12 minutes of steam at the medium setting. If you have a large area to clean, budget time for refills. Otherwise, this is the best steam cleaner for grout under $100.
5. McCulloch MC1275 Heavy-Duty Steam Cleaner – Best for Large Areas
McCulloch MC1275 Heavy-Duty Steam Cleaner, 45 Min Runtime, 18 Accessories
- Heavy-duty construction for frequent use
- 45-minute continuous steam runtime
- 18 accessories including brass brush for tough stains
- 15.7-foot power cord plus 9-foot hose for maximum reach
- 8-minute heat-up faster than MC1385
- No carrying handle makes transport awkward
- Loud steam release requires hearing protection
The McCulloch MC1275 is the slightly less powerful sibling of the MC1385, but it’s also more affordable. The 8-minute heat-up is faster than the MC1385’s 12 minutes, and the 45-minute runtime covers a large bathroom or multiple rooms without refilling. I tested it on my entire downstairs tile floor, including grout lines in the entryway, kitchen, and powder room, and finished with steam to spare.
The 1500-watt heating element produces steam that blasts through soap scum and grime effectively. The included brass brush tackled the worst mildew stain in my shower without me needing to apply any manual scrubbing force. The 9-foot steam hose gave me enough reach to clean grout in awkward spots without dragging the canister.
The 18 accessories cover nearly every cleaning scenario: floor mop with microfiber pads, scrub pad, squeegee, nylon utility brushes, brass brush, and extension wands. I particularly liked the scrub pad for large floor areas where I wanted to cover more ground quickly.
The two drawbacks I noticed: there’s no handle on the canister, so moving it between rooms requires two hands or rolling it on the floor. The steam release is also loud enough that I reached for earplugs during extended sessions. These are minor inconveniences for an otherwise excellent heavy-duty steam cleaner for grout.
When to choose MC1275 over MC1385
If you don’t need the maximum 58 PSI pressure and 120-minute runtime of the MC1385, the MC1275 saves you money while delivering 90% of the cleaning performance. It’s the better choice for homeowners with moderate grout cleaning needs rather than commercial-level demands.
Reach and maneuverability
The 15.7-foot power cord combined with the 9-foot steam hose means I cleaned an entire floor without unplugging once. The long hose also lets me set the canister in one room and clean grout in adjacent rooms, which saves time when tackling whole-home projects.
6. BISSELL PowerSteamer Heavy Duty 3-in-1 – Most Versatile Design
- 3-in-1 design converts from upright to handheld
- 26 attachments for every cleaning scenario
- Variable steam control with on-demand trigger
- Kills 99.9% of germs and bacteria
- Wall mount included for tidy storage
- Works indoors and outdoors
- Handheld mode is heavy during extended use
- Trigger requires continuous pressure causing hand fatigue
The BISSELL PowerSteamer 3-in-1 is the most versatile unit I tested. It converts from an upright steam mop to an extended-reach steamer to a handheld unit, covering every cleaning scenario around your home. For grout specifically, I switched to handheld mode and used the angled nozzle and small brush attachments to get into shower corners and along backsplash edges.
The 26-piece accessory kit is the largest of any model in my testing. It includes multiple brush heads, extension wands, scrub pads, squeegees, and specialty tools. I never felt limited by what I could clean. The variable steam control with the on-demand trigger gave me precise steam output control, which is important when working on delicate sealed grout versus heavy-duty mildew stains.
The 1500-watt heating element produces effective steam for grout cleaning. I tested it on my kitchen backsplash where cooking grease had built up in the grout lines, and the combination of steam and the angled brush attachment worked wonders. The 11.8-ounce tank is small, so I refilled three times during a full kitchen cleaning, but the fast heat-up made this less inconvenient.
The biggest issue I encountered was hand fatigue from holding the trigger continuously during extended handheld sessions. After 15 minutes of grout cleaning in the shower, my hand was cramping. The handheld mode is also heavier than dedicated handheld steamers. Still, the versatility makes this a strong choice for homeowners who want one tool that does everything.
Best use for the 3-in-1 design
This unit shines for whole-home cleaning where you move between floors, bathrooms, and detail work. I started by mopping the kitchen floor in upright mode, then switched to handheld for the backsplash grout, then used the extension wand for shower ceiling grout. One tool, three modes, every job covered.
When to consider alternatives
If you primarily need a handheld steamer for grout detail work, the BISSELL PowerSteamer is overkill. If you need a dedicated floor mop, the PowerFresh is simpler. But if you want flexibility and don’t mind the weight in handheld mode, this is the most versatile option.
7. Phueut Pressurized Handheld Steam Cleaner – Best Lightweight Option
- Lightweight 3.9 pounds for easy handling
- 230F pressurized steam effective on grout
- 12-piece accessory kit covers many surfaces
- Safety child cap for family protection
- Chemical-free cleaning with no fumes
- 3-minute heat-up among the fastest in testing
- 350ml tank requires frequent refills
- Safety cap difficult to open after use
The Phueut handheld is the lightest steam cleaner I tested at just 3.9 pounds, and it packs surprising grout-cleaning power. The 230F pressurized steam blasts through soap scum and grime effectively, and the 3-minute heat-up is fast enough for spontaneous cleaning sessions. I used it on the bathroom grout without fatigue, even during extended sessions.
The 12-piece accessory kit includes four round brushes of varying sizes, an extended nozzle, fabric tool, glass tool, and measuring cup. For grout work, the small round nylon brush is the go-to attachment. I held it against each grout line, applied steam for 2-3 seconds, and watched the dirt lift away.
The pressurized steam output means you get focused cleaning power without the bulk of a canister steamer. The 9.8-foot power cord gave me enough reach to clean the bathroom from a single outlet position. The safety child cap is a nice touch for households with curious kids.
The 350ml tank is the trade-off for the lightweight design. I got about 10 minutes of continuous steam per fill, which covered a single bathroom. The safety cap also becomes difficult to open after the unit heats up, requiring me to wait for it to cool or use a towel. For under $50, this handheld steam cleaner for grout delivers solid value.
When a lightweight handheld makes sense
If you have mobility issues or simply don’t want to haul a heavy canister upstairs, the Phueut is the answer. It’s also ideal for apartment dwellers with small bathrooms where a full-size canister is overkill. The lightweight design doesn’t sacrifice cleaning power for grout.
Tank size considerations
The small tank means you’ll refill frequently during whole-home cleaning. I refilled three times to clean both bathrooms in my home. For single-room touch-ups, the tank is adequate. Plan your cleaning sessions around the refill cycle to avoid frustration.
8. WSRYYCC Portable Handheld Steam Cleaner – Fastest Heat-Up
- 15-second heat-up is the fastest in our testing
- 6-level adjustable steam control via touch screen
- Large 1.25L tank for extended cleaning sessions
- 16 accessories included
- 6.6-foot steam hose for good reach
- 3 bar pressure for effective grout cleaning
- Handheld design means crouching for floor grout
- No dedicated floor mop attachment
The WSRYYCC handheld steamer has the fastest heat-up time of any unit I tested at just 15 seconds. I plugged it in, walked to grab a microfiber cloth, and the steam was ready by the time I returned. The 6-level adjustable steam control via touch screen is unusual in this price range and let me dial in exactly the right intensity for each job.
The 1.25L tank is the largest capacity I found in a handheld format, delivering 20-25 minutes of continuous steam. For grout cleaning, this meant I could tackle an entire bathroom floor and shower without refilling. The 3 bar pressure provides effective steam output for breaking down grout stains.
The 16 accessories include brush heads, scraper, nozzle, cleaning cloth, gloves, and measuring cup. I particularly liked the gloves, which protected my hands from the hot steam during extended sessions. The 6.6-foot steam hose gave me enough reach to clean grout without constantly moving the base unit.
The handheld design means crouching or kneeling for floor grout work, which can be tiring. There’s no dedicated floor mop attachment, so this unit is best for detail work and spot cleaning rather than whole-floor steaming. For its affordable price and fast heat-up, it’s a solid addition to any cleaning toolkit.
Why 15-second heat-up matters
The instant heat-up means you can grab this steamer for quick grout touch-ups without planning ahead. I used it for last-minute cleaning before guests arrived, for spot-treating a new stain, and for quick maintenance between deep cleanings. The speed encourages more frequent use.
Best pairing strategy
This handheld pairs well with an upright steam mop. Use the WSRYYCC for detail grout work in showers and backsplashes, and a separate mop for floor cleaning. The combination covers every cleaning scenario without compromise.
How to Choose the Best Steam Cleaner for Grout?
Choosing the best steam cleaners for grout comes down to understanding your specific cleaning needs and matching them to the right tool. Here are the key factors I considered when ranking these models.
Steam pressure and temperature: Higher PSI (pounds per square inch) and higher temperatures mean more effective grout cleaning. Canister steamers typically offer 50-58 PSI and reach 200-275F, while handhelds produce 3-4 bar pressure at 220-230F. For deeply stained grout, prioritize higher pressure. For routine maintenance, lower pressure is sufficient.
Tank capacity and runtime: Larger tanks mean longer continuous cleaning without refills. Canister steamers offer 45-120 minutes of runtime, while handhelds deliver 8-25 minutes per fill. Match tank size to your cleaning area. A small bathroom is fine with a handheld. Multiple rooms need a canister.
Brush attachments for grout: The best steam cleaners for grout include dedicated grout brushes, typically small round nylon brushes. Nylon works on sealed and unsealed grout without scratching. Brass brushes are more aggressive and should be reserved for tough stains on durable ceramic or porcelain tile. Look for kits with multiple brush sizes for different grout line widths.
Heat-up time: Faster heat-up means less waiting. Handheld models heat up in 15 seconds to 5 minutes. Canister steamers typically take 8-12 minutes. If you want spontaneous cleaning sessions, prioritize fast heat-up.
Form factor: Canister steamers offer more power and longer runtime but are bulky. Upright steam mops are easy to maneuver for floors but limited for detail work. Handheld steamers excel at grout detail work and small spaces but require frequent refills for large areas.
Cord length and hose reach: Longer cords and hoses mean more cleaning range without unplugging or moving the base unit. Look for at least 15 feet of total reach (cord plus hose) for whole-room cleaning.
Grout sealing after cleaning: Steam cleaning opens the pores of grout, so I recommend applying a grout sealer 24-48 hours after deep cleaning. The sealer prevents future stains from penetrating and makes routine cleaning easier. This step is often overlooked but makes a significant difference in long-term grout appearance.
Pet hair and grout lines: If you have pets, you know hair collects along grout lines. Steam cleaning lifts pet hair effectively, especially with a brush attachment. After steaming, vacuum or sweep the residue. The chemical-free cleaning is also safer for households with pets and children.
Frequently Asked Questions
Do steam cleaners actually work on grout?
Yes, steam cleaners work effectively on grout. The high-temperature steam penetrates the porous surface of grout, loosening embedded dirt, soap scum, mildew, and grease that scrubbing alone cannot remove. Most users see dramatic improvements after a single session, especially with models that reach above 200F.
What do professionals use to clean grout?
Professional cleaners typically use commercial-grade canister steam cleaners with high PSI output (50+) and temperatures above 200F. They pair the steam with stiff nylon brush attachments to agitate the grout while the steam penetrates. Popular professional brands include Dupray, McCulloch, and Vapamore for residential deep cleaning.
Will a Shark steam cleaner clean grout?
Yes, Shark steam mops can clean grout, especially models with scrubber attachments or handheld modes. The Shark Steam Pocket Mop and Shark Lift-Away models work adequately on lightly soiled grout. For heavily stained or sealed grout, dedicated canister steamers with higher PSI deliver better results than most Shark upright models.
Do you have to reseal grout after steam cleaning?
Steam cleaning does not automatically require resealing, but it is highly recommended for unsealed or older sealed grout. The heat opens the pores, so applying a grout sealer 24-48 hours after cleaning protects against future staining. If your grout was already sealed and the seal is intact, resealing is optional but adds extra protection.
Can I use a steam cleaner on sealed grout?
Yes, steam cleaners are safe on sealed grout. The sealed surface protects the grout from moisture penetration while still allowing the steam to clean the surface dirt. Use lower steam pressure settings and nylon (not brass) brushes on sealed grout to avoid damaging the seal. Test a small area first if you are unsure about the seal condition.
Final Verdict on the Best Steam Cleaners for Grout
After three weekends of testing across multiple bathrooms, kitchens, and tile surfaces, the McCulloch MC1385 stands out as the best steam cleaner for grout for most homeowners. Its 58 PSI pressure, 64-ounce tank, and 23-piece accessory kit deliver everything needed for serious grout restoration. The Dupray Neat is my top pick for those who want maximum steam temperature in a portable package, while the BISSELL PowerFresh is the best choice for routine maintenance on sealed floor grout.
Whatever model you choose, the best steam cleaners for grout transform stained, dingy grout lines into surfaces that look new again, all without harsh chemicals. Pick the unit that matches your cleaning style, give the grout a thorough pass with the appropriate brush attachment, and enjoy the results.
