Knowing how to clean stone floors correctly is essential because different stone types have very different chemistries — and the wrong cleaner can cause permanent damage. A product that is perfectly safe for granite may etch and dull marble. A technique that works beautifully on slate may stain limestone. There is no universal stone floor cleaner, and this guide explains exactly what each type needs.
This guide covers cleaning, sealing, stain removal, polishing, and professional restoration for the five most common stone flooring types: marble, granite, slate, travertine, and limestone.
General Rules for All Stone Floors
Before diving into type-specific care, these universal rules apply to every natural stone floor.
Dust mop frequently. Grit is the enemy of stone floors. Sand and dirt particles grind against the surface with every footstep, gradually dulling the finish. A daily or every-other-day pass with a dry microfiber dust mop prevents this damage more effectively than any cleaning product.
Wipe spills immediately. All natural stone is porous to some degree. The longer a spill sits, the deeper it penetrates and the harder it is to remove. Acidic spills (citrus juice, wine, vinegar, tomato sauce) are especially damaging to calcium-based stones like marble, travertine, and limestone.
Use pH-neutral cleaners. Acidic cleaners (vinegar, lemon juice, most bathroom cleaners) damage calcium-based stones. Alkaline cleaners (ammonia, bleach) can discolor and dull stone surfaces. pH-neutral, stone-specific cleaners are always the safest choice.
Never use generic floor cleaners. Products designed for tile, hardwood, laminate, or general-purpose cleaning often contain acids, alkalis, or waxes that damage stone. Always use a cleaner specifically formulated for natural stone.
Use doormats and felt pads. Protect stone floors with doormats at entrances (to trap grit) and felt pads under all furniture legs (to prevent scratches). These inexpensive preventive measures save thousands in restoration costs over time.
Marble Floor Care
Marble is a calcium-based stone that is softer, more porous, and more chemically reactive than granite. It is beautiful but demands the most careful cleaning of any stone type.
Cleaning
Use only pH-neutral cleaners. Marble etches (develops dull spots) when exposed to any acidic substance. This includes vinegar, lemon juice, tomato sauce, wine, orange juice, and many common household cleaners. Even mildly acidic cleaners that are safe for granite will damage marble.
Recommended products: StoneTech Stone & Tile Cleaner, Granite Gold Daily Cleaner (despite the name, it is pH-neutral and safe for marble), and Method Daily Granite Cleaner are all pH-neutral and safe for daily marble use.
Mopping technique: Damp mop with a well-wrung microfiber mop and a pH-neutral stone cleaner. Avoid excess water — marble is porous and absorbs moisture through the surface and grout lines. Dry the floor with a clean, soft cloth after mopping to prevent water spots on polished marble.
Special Concerns
Marble etching is the most common issue. Etch marks appear as dull, lighter spots on polished marble where acid has dissolved the surface. Light etching can be buffed out with marble polishing powder. Deep etching requires professional honing. Prevention — wiping acidic spills immediately and using only pH-neutral products — is far easier and cheaper than repair.
Granite Floor Care
Granite is the hardest and most forgiving common stone flooring. It resists scratches, stains, and etching far better than marble, travertine, or limestone — making it the lowest-maintenance stone floor option.
Cleaning
Mild detergent works well. Granite is not as chemically sensitive as marble. A few drops of mild dish soap (non-antibacterial, no lotion) in a bucket of warm water cleans granite floors effectively. Alternatively, use any pH-neutral stone cleaner.
Recommended products: StoneTech Stone & Tile Cleaner, Granite Gold Daily Cleaner, or plain warm water with a drop of dish soap. For deeper cleaning, StoneTech Professional Stone & Tile Deep Cleaner handles heavy soil and grease.
Mopping technique: Damp mop with your chosen solution and a microfiber mop. Granite tolerates slightly more moisture than marble but should still not be soaked. Buff dry if a streak-free shine is desired, though granite is forgiving about water spots.
Special Concerns
Granite’s primary vulnerability is staining — particularly from oil-based substances (cooking oil, grease, cosmetics). While granite is less porous than marble, unsealed or poorly sealed granite can absorb oily liquids that create dark stains. Keeping the sealer up to date (see sealing schedule below) prevents this issue.
Slate Floor Care
Slate is a layered metamorphic stone with a naturally textured, cleft surface that gives it rustic character. Its unique texture requires slightly different cleaning approaches than smooth stones.
Cleaning
Avoid acid-based cleaners. While slate is more acid-resistant than marble, acidic cleaners can still strip sealers and dull the surface over time. Stick to pH-neutral stone cleaners or mild soap solutions.
Recommended products: StoneTech Stone & Tile Cleaner, or a solution of warm water with a few drops of mild dish soap. For slate’s textured surface, a soft-bristled brush (not stiff bristles) helps work cleaner into the cleft texture.
Mopping technique: Slate’s textured surface traps dirt in its natural ridges and valleys. A flat microfiber mop may not reach into these recesses. Use a damp microfiber mop for routine cleaning and a soft brush with stone cleaner for periodic deep cleaning (monthly or as needed). Rinse thoroughly to prevent cleaner residue from building up in the texture.
Special Concerns
Slate can flake along its natural layers if the surface sealer breaks down and moisture penetrates. Maintain the sealer on schedule (annually for most environments) to prevent moisture intrusion. Avoid abrasive scrubbing that can loosen surface layers. Some slate varieties shed small flakes naturally — this is a characteristic of the stone, not a sign of damage.
Travertine Floor Care
Travertine is a calcium-based stone (like marble and limestone) with characteristic surface pits and vein patterns. It is popular for its warm, earthy tones and Mediterranean aesthetic — but its calcium composition makes it vulnerable to acid damage.
Cleaning
No vinegar, ever. Vinegar is one of the most commonly suggested DIY floor cleaners on the internet — and it is one of the most destructive substances you can put on travertine. The acetic acid dissolves the calcium carbonate that makes up the stone, causing etching, dulling, and permanent surface damage.
Recommended products: StoneTech Stone & Tile Cleaner, Granite Gold Daily Cleaner, or any cleaner explicitly labeled as safe for travertine and calcium-based stones. When in doubt, warm water alone is safer than any questionable product.
Mopping technique: Damp mop with a pH-neutral cleaner and a well-wrung microfiber mop. Travertine’s surface pits (even filled and honed travertine has micro-pits) can trap dirt. Periodic deeper cleaning with a soft brush helps clean these areas. Avoid flooding the floor — travertine absorbs water readily.
Special Concerns
Filled travertine (where the natural surface holes have been filled with grout or epoxy) can lose its fill over time due to foot traffic and cleaning. If fills begin to crack or come loose, they can be refilled by a stone restoration professional. Unfilled travertine requires more frequent cleaning because the open holes trap dirt and debris.
Limestone Floor Care
Limestone is the softest and most porous of the common stone flooring types. It requires the gentlest care and the most diligent sealing to maintain its appearance.
Cleaning
Gentle is the operative word. Limestone scratches more easily than other stones, absorbs stains more readily, and etches from acid exposure just like marble and travertine. Use only the mildest pH-neutral cleaners and the softest tools.
Recommended products: StoneTech Stone & Tile Cleaner (diluted), warm water with a tiny amount of pH-neutral soap, or a limestone-specific cleaner. Avoid anything with acid, ammonia, bleach, or abrasives.
Mopping technique: Use a very well-wrung microfiber mop with minimal cleaner. Limestone absorbs moisture faster than granite or slate, so excess water causes darkening that takes hours to evaporate. Work in small sections and dry each section promptly.
Special Concerns
Limestone’s softness means it develops a visible wear pattern over time in high-traffic areas — the stone literally wears down under foot traffic. This patina is considered desirable by many homeowners (think of the worn limestone floors in historic European buildings), but if you prefer a uniform appearance, consider professional honing every 5 to 10 years to restore evenness.

| Sealing frequency | Every 6 – 12 months | Every 1 – 3 years | Every 1 – 2 years | Every 6 – 12 months | Every 6 – 12 months |
Sealing Schedule
Sealing is the single most important maintenance task for natural stone floors. A quality penetrating sealer fills the stone’s pores, preventing liquids and stains from being absorbed while allowing moisture vapor to escape.
How to test if your stone needs resealing: Place a few drops of water on the stone surface in a high-traffic area. If the water beads up and sits on the surface, the sealer is still working. If the water soaks in and darkens the stone within 5 minutes, it is time to reseal.
| Stone Type | Sealing Frequency | Recommended Sealer | Cure Time |
|---|---|---|---|
| Marble | Every 6 – 12 months | StoneTech BulletProof Sealer | 24 hours |
| Granite | Every 1 – 3 years | Granite Gold Sealer | 24 hours |
| Slate | Every 1 – 2 years | Miracle Sealants 511 Impregnator | 24 – 72 hours |
| Travertine | Every 6 – 12 months | StoneTech BulletProof Sealer | 24 hours |
| Limestone | Every 6 – 12 months | StoneTech BulletProof Sealer | 24 hours |
Sealing process: Clean the floor thoroughly and allow it to dry completely (24 hours minimum). Apply the penetrating sealer with a clean applicator pad or microfiber cloth, working in small sections. Allow the sealer to penetrate for the manufacturer’s recommended time (typically 5 to 15 minutes), then wipe away any excess before it dries on the surface. Apply a second coat if directed. Allow full cure time before foot traffic.
Stain Removal for Stone Floors
The stain removal approach depends on the type of stain and the type of stone. The method that works for all stone types is a poultice — a paste that draws the stain out of the stone.
Oil-Based Stains (Cooking Oil, Grease, Cosmetics)
Mix baking soda with water to form a thick paste. Spread the poultice over the stain approximately 1/4 inch thick and extend 1 inch beyond the stain edges. Cover with plastic wrap, tape the edges, and poke a few small holes. Let it sit for 24 to 48 hours, then remove and rinse. Repeat if needed. This method is safe for all stone types.
Organic Stains (Coffee, Tea, Wine, Food)
For granite and slate, a poultice of baking soda mixed with hydrogen peroxide (12% solution) works well. For marble, travertine, and limestone, use baking soda mixed with water only (peroxide can lighten some calcium-based stones). Apply as described above.
Rust Stains
Rust stains on stone are among the most difficult to remove. Commercial rust removers for stone (like StoneTech Rust Remover) are formulated to remove rust without damaging the stone. Do not use generic rust removers — they contain acids that will etch marble, travertine, and limestone.
Etch Marks (Marble, Travertine, Limestone)
Etch marks are not stains — they are chemical reactions where acid has dissolved the stone surface. Light etching on polished stone can be removed with marble polishing powder (tin oxide) applied with a damp cloth and buffed in circular motions. Deep etching requires professional honing with diamond abrasives.
Polishing and Professional Restoration
DIY polishing is limited to light maintenance on polished marble and granite. Marble polishing powder restores minor dullness and light etch marks. Granite polishing creams add sheen and fill micro-scratches. Apply with a soft cloth, buff in circular motions, and wipe clean.
Professional restoration is necessary when stone floors have deep scratches, significant etching, uneven wear patterns, or stubborn stains that poultice treatments cannot remove. Professional stone restoration involves diamond honing (grinding the surface with progressively finer diamond abrasives to remove damage and restore smoothness) followed by polishing to the desired finish level.
Professional stone restoration typically costs $3 to $10 per square foot, depending on the severity of damage and desired finish. For a 200-square-foot area, expect $600 to $2,000. This service restores stone floors to near-original condition and is recommended every 5 to 15 years depending on traffic and maintenance quality.
Frequently Asked Questions
Can I use vinegar to clean stone floors?
Only on granite and slate, and even then, diluted vinegar should be used sparingly. Never use vinegar on marble, travertine, or limestone. Vinegar is acidic and will etch and dull these calcium-based stones permanently. pH-neutral stone cleaners are always the safer choice for all stone types.
How often should I clean stone floors?
Dry dust mopping should be done daily or every other day. Damp mopping with a stone cleaner should be done weekly for most households. Wipe spills immediately regardless of stone type. This routine keeps stone floors clean and prevents the grit accumulation that dulls surfaces over time.
Can I use a steam mop on stone floors?
Steam mops are not recommended for natural stone floors. The heat and moisture can break down sealers prematurely, force water into the stone’s pores, and potentially damage grout. Use a damp microfiber mop instead.
Why is my marble floor dull even after cleaning?
Dull marble is almost always caused by etching from acidic substances — even mildly acidic cleaners, spilled drinks, or cleaning products not designed for marble. The dullness is physical damage to the stone surface, not dirt. Light etching can be buffed out with marble polishing powder; extensive dulling requires professional honing.
What is the easiest stone floor to maintain?
Granite is the easiest natural stone floor to maintain. Its hardness resists scratches, its low porosity resists stains, and its acid resistance means more cleaners are safe to use. Granite floors need sealing only every 1 to 3 years and tolerate a wider range of cleaning products than other stone types.
How much does professional stone floor restoration cost?
Professional stone floor restoration costs $3 to $10 per square foot, depending on the stone type, extent of damage, and desired finish. A typical living room (300 square feet) costs $900 to $3,000 to professionally hone and polish. The result is dramatic — heavily worn and damaged stone can be restored to near-original condition.
