Marble floors add timeless elegance and luxury to any space. From upscale bathrooms to high-end kitchens, their glossy finish and natural veining make them a designer favorite. But maintaining that shine takes care and the right techniques. Marble may be durable, but it's surprisingly sensitive to acidic cleaners, abrasive tools, and everyday grime. Whether you're dealing with dullness, stains, or just everyday dust, this guide walks you through how to clean marble floors properly. We'll cover everything from daily maintenance to deep cleaning, plus smart solutions using modern vacuum tech to help you preserve your floors for years to come. Types of Marble Surfaces: Why They Need Special Care Marble is metamorphic limestone, composed primarily of calcium carbonate. This gives it two vulnerable characteristics: Porosity: It absorbs liquids quickly. Acid sensitivity: Even weak acids like lemon juice or vinegar cause permanent etching. Marble Finish Types & Their Needs Marble comes in several finishes, and each one needs slightly different care: Finish Type Appearance Vulnerability Ideal Locations Polished Glossy, mirror-like shine Shows scratches and etches easily from acidic spills Formal living areas, lobbies, and hallways Honed Soft matte finish Hides scratches better but shows stains more easily Kitchens and bathrooms Tumbled Textured, aged look Most stain-resistant Shower floors, outdoor patios, pool decks Understanding the finish and location of your marble helps you choose the safest and most effective cleaning approach. Pro-tip: Always test cleaning products on a small, hidden area first to avoid damage. How to Clean Marble Floors Routine maintenance is the best way to preserve the beauty of your marble floors. Let's break it down into a few smart categories. Already dealing with dull patches or haze? Start with these common floor-cleaning mistakes. Daily Maintenance Dust and debris can cause tiny scratches. Sweep or vacuum daily with a soft-bristle brush or a robot vacuum (like the Dreame X60 Ultra) on a vacuum-only pass to pick up dirt without damage. Wipe spills immediately, especially acidic liquids like wine, coffee, or citrus juices. For kitchens and bathrooms, a wet and dry vacuum is a safe and effective way to handle spills and splashes. Read this wet and dry vacuum buying guide on how to choose the best one. Weekly Cleaning Pre-treat stains (see stain removal section below). Use a pH-neutral cleaner or mild dish soap mixed with warm water. A wet and dry vacuum like the Dreame Aero Pro puts the water down and picks it back up in the same pass, so the stone is never left sitting wet. Its TangleCut™ 2.0 scraper cuts hair off the roller as it spins, and the dock washes and dries the roller afterwards. For a streak-free shine, dry with a microfiber cloth. If cleaner residue is left behind, here is how to clean sticky floors for good. Monthly Treatment Grout cleaning using a baking soda paste and a soft brush. Inspect the furniture pads and replace any worn felt protectors. Check the sealant by sprinkling water on it; if the stone darkens, then reseal it. Dreame Take: A delicate floor should not need a different machine. We design our robot vacuums to read the surface underneath them and keep wet work separate from dry work on their own, so you are not the one remembering which setting marble needs. How to Clean Marble Floors Naturally Prefer a chemical-free approach? Here's how to naturally clean marble floors without harsh ingredients: Mix a few drops of mild dish soap with warm water. Use baking soda paste for stains. Use a soft microfiber mop dampened (not soaked!) in the solution. Rinse with clean water and dry with a towel to avoid water spots. Important: Avoid vinegar, lemon, ammonia, or any acidic cleaners, because they can etch and dull marble surfaces. How to Clean Grout in Marble Floors Grout can trap grime and mildew and affect the overall look of your floor. Here's how to refresh it: Use a soft toothbrush or grout brush. Apply a paste of baking soda and water, let it sit for 5–10 minutes, and gently scrub. Rinse with a damp mop and dry the area thoroughly. How to Remove Stains from Marble Floors Stains can set quickly on marble, especially in bathrooms or kitchens. Here's how to treat them: Type of Stain Solution Water stains Buff gently with a dry microfiber cloth. Use a pH-neutral marble cleaner if needed. Pet stains (like urine) Clean immediately. Use a damp cloth with mild soap. Avoid ammonia-based products. Oil-based stains Sprinkle cornstarch or baking soda, let it sit overnight, and vacuum. Organic stains (like coffee or wine) Use a poultice paste (baking soda + water) and cover with plastic wrap. Leave for 24 hours. Pro-tip: Always do a spot test before applying any solution over a large area. How to Clean a Marble Shower Floor Marble shower floors are exposed to constant moisture, so they need extra care. Here's how to best clean them: Use a non-slip brush or mop with a pH-neutral cleaner. Rinse thoroughly and dry the area to prevent soap scum or mildew. Keep good airflow in the bathroom with fans or dehumidifiers. What's the Best Cleaner for Marble Floors? The best marble floor cleaners are pH-neutral, non-abrasive, and made specifically for natural stone. Look for labels that mention: "Safe for marble" "pH-neutral" "No acids or ammonia" Dilution matters as much as the label. Check out this Vacuum Cleaning Solution article on how to choose the right solution for your floor. For households with kids or pets, choosing natural or eco-friendly options can be a safer and healthier choice. How to Deep Clean Marble Floors Even with regular maintenance, marble needs deep cleaning every few weeks or after high traffic. First, Work Out Whether It Is a Stain or an Etch Before you clean anything, look closely at the marks you want gone, because stains and etches need opposite treatments. A stain is darker than the stone and sits in the pores, so cleaning can draw it out. Dry Soil Removal, Including the Edges Remove every bit of dry grit before liquid touches the floor. Vacuum with a soft roller head or a robot vacuum, then go back over the perimeter, the seams and the doorway thresholds by hand with a soft brush, since that is where grit collects and where a mop will drag it. Deep Clean With Dwell Time, Not a Quick Pass Apply a diluted pH-neutral stone cleaner and let it sit for five to ten minutes before you agitate it. This is the step people skip, and it is the one that does the work: the cleaner needs time to lift the greasy film that binds soil into the pores. Draw Out Set-In Stains With a Poultice For stains that survive the deep clean, a poultice pulls them up out of the stone instead of scrubbing at the top of them. Mix baking soda with water into a thick paste about the consistency of peanut butter, spread it roughly a quarter inch (6 mm) thick, and extend it half an inch (13 mm) past the edge of the stain. Clean Seams and Grout Lines Separately Give the seams their own pass with a soft brush and the same pH-neutral cleaner. Grout sits lower than the tile, so a flat mop glides straight over it and leaves a dark line that makes the whole floor look unclean. Work along the joint rather than across it, and keep the brush soft: a stiff nylon brush will scratch a polished edge. Rinse Twice, Then Dry Completely Rinse with clean water twice, changing the water between passes. Cleaner residue left on marble attracts soil faster than the original dirt did, which is the usual reason a floor looks dull again within a week. Finish With a Sealer Check Test the sealer while the floor is clean and dry, since that is the only time the result is reliable. Sprinkle a few drops of water on two or three spots, wait ten minutes, then wipe them away. Marble Floor Cleaning Tips Keep your floors gleaming with these smart habits: Use entry mats to reduce tracked-in dirt. Avoid dragging furniture. Use felt pads under furniture to prevent scratches. Enable scheduling on your Dreame robot vacuum for daily dust control to prevent buildup. Dry spills quickly, especially in kitchens or on marble shower floors. Rotate rugs and mats to prevent uneven wear or discoloration. Use slippers indoors to minimize grit from shoes. Polish every few months using a marble-safe polish to restore shine. Seal marble annually to protect against stains. FAQs How often should I clean marble floors? Dry mop or vacuum weekly. Deep clean monthly or as needed. Can I use vinegar to clean marble floors? No. Vinegar is acidic and can damage marble. Always use pH-neutral cleaners. What's the best way to clean marble shower floors? Use a non-slip brush and a marble-safe cleaner. Rinse well and dry to avoid soap scum. Are steam mops safe for marble? It's best to avoid them. The high heat can damage the sealant and lead to dull spots. What if my marble floor has etching? Etching needs professional polishing. Avoid acidic products to prevent further damage. How often should I seal marble floors? Every 6–12 months, depending on traffic. Are robot mops safe for marble? Yes, as long as they mop with water or a marble-safe solution and never anything acidic. Dreame's X60 Ultra mops with warm water and washes its own mop pads between runs. Top Picks for Marble Floor Care Marble needs two things from a machine: something that lifts grit before it gets ground into the surface, and something that handles water without leaving any behind. Neither job needs a special marble setting. They need doing consistently. For daily dust: the Dreame X60 Ultra Robot Vacuum. It lifts the grit that causes fine scratches, and its brush clears long hair instead of winding it around the roller. [product handle="x60-ultra-robot-vacuum" slogan="Best for Daily Marble Care"] For weekly mopping: the Dreame Aero Pro Wet and Dry Vacuum. Its head lies flat, so it reaches under low furniture where a mop head will not go. Both still sit alongside a spot test and a pH-neutral bottle. Final Thoughts Keeping marble floors clean doesn't have to be complicated. With the right tools and routines, you can protect your investment and enjoy their stunning finish for years to come. Get the gentle routine right and the stone holds its finish on its own. Both picks above sit in Dreame's full collection of robot vacuums if you want to compare them side by side.

It can be annoying: The grout between tiles on your floor remains dingy no matter how hard and often you scrub. In fact, the more you polish, the more the shiny tiles seem to highlight the grimy grout. It’s not a sign of poor cleaning. Learning how to clean floor tile grout really boils down to a little bit of chemistry, often using nothing but safe household items. But before you get down to more scrubbing you should understand the type of grout you’re dealing with: 1. Types of Grout: Know What You're Cleaning Sanded grout is often used for wide grout lines. The sand provides bulk, making it ideal for ceramic, porcelain and natural stone tiles where a rustic look or larger joint is desired. Unsanded grout is used for thinner joints or highly polished tiles. Epoxy grout fights stains, chemicals and moisture, making it an excellent choice for busy areas, bathrooms and shower floors. For sanded grout, a paste made of baking soda and water helps deep clean. For tougher stains, consider a hydrogen peroxide and baking soda paste. For unsanded grout, diluted white vinegar can clean and sanitize. Steam cleaning is also a great chemical-free option. For epoxy grout, simple warm water with a few drops of dish soap is usually enough for routine cleaning. For any remaining haze or stubborn post-installation residue, a specialized epoxy grout cleaner might be the answer.  Most of these are already in your home. Our cleaning supplies checklist covers the rest. 2. Must-Have Grout Cleaning Supplies and Tools Item Description Grout cleaner For tough stains and deeply embedded dirt Grout brush Stiff, narrow bristles to scrub grime Bucket For cleaning solutions and rinse water Microfiber cloth or sponge Highly absorbent for wiping and drying Rubber gloves Protect your hands from solutions and dirt Wet dry vacuum Hot water cleaning and extraction Homemade grout cleaner can include vinegar, baking soda or hydrogen peroxide to provide safe, chemical-free cleaning. Pro-tip A big help is a wet dry vacuum that can break apart stubborn stains, then rinse and dry afterward. The Dreame H15 Pro Heat Wet Dry Vacuum gives tiles wash at 185°F (85°C), then sucks up the loosened dirt, debris and stains. [product handle="h15-pro-heat-wet-dry-vacuum" slogan="Editor’s Pick"] 3. How to Clean Grout Between Floor Tiles, Step by Step Baking soda paste, a vinegar spray, twenty minutes and a stiff brush will lift most of what is in a floor grout line. Bathroom and kitchen grout differ, though: epoxy in the bathroom for water resistance, sanded in the kitchen for the wider joints. For the machine side of it, see wet and dry vacuums for multi-surface cleaning. Depending on the type and size of the room, steam cleaning could be the preferred solution. Hand cleaning techniques use chemical-free household ingredients while an advanced wet-dry vacuum aids in both preparation and finishing the process. Here is a step-by-step guide to how to clean grout between tiles. Prepare the surface: Use a wet dry vacuum to remove loose dirt and debris. Make a baking soda paste: Mix baking soda with a little warm water to create a thick paste.   Apply the baking soda paste: Using your finger or a spoon, apply the baking soda paste directly onto the grout lines. Prepare the vinegar solution: In a spray bottle, mix equal parts white vinegar and warm water. Spray the vinegar: Spray the vinegar solution directly onto the baking soda paste on the grout. You'll notice a fizzing reaction. Let it sit: Allow the mixture to sit on the grout for up to 20 minutes. Scrub the grout: Using a stiff-bristled brush, scrub the grout lines in a circular motion. Some people use an old toothbrush while others buy a purpose-made brush.Once the brush is in hand, apply firm pressure to work the paste into the grout and loosen embedded dirt. For stubborn stains, you might need to apply more elbow grease. Note: if you would rather skip step 7, the Dreame H15 Pro Heat Wet Dry Vacuum washes the tile at 185°F (85°C) and pulls the loosened grime straight out, so most floor grout comes up without scrubbing. Once the grout is clean you want to keep it that way. A sealant will help prevent grimy buildup. Quick Guide to Cleaning Tile Grout Method Best for Pros Cons Baking soda + vinegar paste Cement-based grout Inexpensive, natural Requires scrubbing Steam cleaning Epoxy or sensitive grout Chemical-free, less manual Need equipment Wet dry vacuum All floor grout Hot water deep clean, dries fast More costly upfront 4. Why You Need to Seal Grout You need to seal grout to protect it from stains, moisture and future discoloration. Without a sealant, grout absorbs water and dirt easily, leading to mold, mildew, and stubborn stains over time. After the hard work of getting those grout lines back shiny as new, it is a good idea to apply some sealant. How often it’s applied and the type of sealant can vary according the room’s use. Main bathrooms, kitchen floors, entryways and high-moisture areas such as showers should be sealed more often. Recommendations range from every six months to one year. Low-traffic areas like guest bathrooms and laundry rooms might only need sealing every one to two years or even longer. Different sealants for different floors The primary sealant types are penetrating sealers and membrane-forming sealers. Penetrating sealers, also known as impregnators, are highly recommended because s they absorb into cement-based grout, forming an invisible, breathable barrier that repels water and stains without changing the grout's appearance. Membrane-forming or topical sealers for high-moisture areas create a surface coating that can give a specific finish. For most common cement-based grouts in wet environments, a penetrating sealer provides the best protection. Now establish a routine that stops daily buildup. 5. Prevent Buildup on Grout To prevent future grout discoloration and haze, robot vacuum and mop combinations such as the Dreame L40 Ultra Gen2 Robot Vacuum are excellent for maintaining tile floors, keeping them dust- and spill-free with minimal effort. It vacuums the loose grit first, then mops, which is the order that matters: dry debris left on the floor turns into the paste that settles into a grout line. Smart mapping means the kitchen and bathroom get done on a schedule rather than when you remember. A routine of using a wet dry vacuum to keep surfaces clean is also recommended to deter dirt from settling in the grout between tiles. If you are choosing one, the wet and dry vacuum collection sorts them by floor type and tank size. You are certainly not alone if you have trouble cleaning the grout between tiles on your floor. It's a challenge in almost every home. Frequently asked questions include:  Frequently Asked Questions About Cleaning Grout What is the best way to clean grout on tile floors? The best way to clean grout on tile floors is to use a stiff brush with the right cleaning solution such as a paste of baking soda or hydrogen peroxide. For an effective and chemical-free deep clean, a wet dry vacuum cleaner is highly recommended because it uses hot water to loosen embedded dirt and grime. How often should I clean my tile grout? You should deep clean your tile grout at least once a year. However, in high-traffic areas, kitchens and bathrooms, more frequent deep cleaning might be necessary, perhaps two or more times a year. How do professionals clean tile grout? Professionals clean tile grout by first applying specialized pre-treatment solutions to loosen embedded dirt and grime. They then use equipment such as high-pressure hot water extractors or rotary scrubbing machines with specialized brushes to thoroughly clean and rinse the grout lines, often following up with a sealant to protect the newly cleaned surface. How much does grout cleaning cost? The cost of professional grout cleaning typically ranges from $0.50 to $3.50 per square foot, though many companies have a minimum charge, often between $100 and $200. Factors influencing the final price include the total area to be cleaned, the condition of the grout, the type of tile, and whether additional services like sealing or repair are included. How do you clean grout without scrubbing? Let the chemistry do the work, then extract rather than wipe. Spread a baking soda paste, spray it with a vinegar solution, and leave it twenty minutes so the grime lifts on its own. A hot water wet dry vacuum then pulls it out of the joint instead of pushing it back in, which is what a mop and bucket do. What should you not clean grout with? Keep bleach, ammonia and any acidic cleaner off cement-based grout. Bleach and ammonia strip the sealant and can lighten the grout unevenly, and acids eat into the cement itself. Steel wool and hard-bristled metal brushes do the same damage mechanically. Stick to baking soda, hydrogen peroxide or a diluted vinegar solution. Getting a tile floor back to how it looked when it was new is not a mission impossible. A little kitchen chemistry, the right tool for the rinse, and the grout lines come back.
