Which Cleaning Products Are Safe for Natural Stone?
One rule covers most of it: pH-neutral only. Vinegar, lemon, bleach, and tub-and-tile cleaners can permanently etch marble in seconds. Here’s what’s safe, what isn’t, and when to bring in a pro.
The One Rule: pH-Neutral
Natural stone — marble, travertine, limestone, and onyx — is calcium-based and reacts with acids. The single rule that prevents most damage: use only pH-neutral cleaners made for stone. Acidic and strongly alkaline products etch the surface, leaving dull marks no polishing fully removes.
What to Never Use
Keep these off natural stone: vinegar and lemon (common “natural” cleaners that are acidic), bathroom and tub-and-tile cleaners, bleach, ammonia, and abrasive powders or pads. Many all-purpose sprays are also too harsh. If a product doesn't say it's safe for stone, assume it isn't. See natural-stone tile care for the full picture.
What to Use
A dedicated pH-neutral stone cleaner, or simply warm water with a drop of mild dish soap for routine wiping, plus a soft microfiber cloth. Blot rather than scrub, and dry the surface to avoid water spots on polished finishes.

Handling Spills
On stone, spills are a race — wine, citrus, coffee, and anything acidic should be blotted (not wiped) immediately, because etching happens fast. Sealing helps buy time against staining; see sealing explained.
When to Bring a Pro
For deep cleaning, restoring etched or dull stone, or sealing, a specialist is worth it — the cost of a mistake on stone is far higher than on tile.
Stone by stone: what each tolerates
Marble, travertine, limestone, and onyx are calcium-based and etch on contact with anything acidic — vinegar, lemon, wine, tomato, many bathroom cleaners. pH-neutral only, no abrasives, and seal on schedule. Granite is silica-based and far more acid-tolerant, but it’s porous and its polish is still dulled by abrasives and harsh alkalines; treat it as pH-neutral too and keep it sealed. Quartzite is hard and largely acid-resistant, with one caveat: some stone sold as “soft quartzite” is actually marble and etches like it, so test an inconspicuous spot with a drop of lemon before assuming. Slate handles neutral cleaners well but should never see acids, oils, or wax, which build up in its layered surface. Engineered quartz isn’t natural stone at all — it’s quartz bound in resin — and the resin is what fails: no bleach, no abrasive powders, no hot pans, and no solvents.
Sealing: how often, and how to test
A penetrating sealer slows absorption; it doesn’t stop etching, which is a chemical reaction with the surface. Test rather than guess: put a few drops of water on the stone and wait ten minutes. If it beads, the seal is working; if it darkens the stone, it’s time to reseal. Polished marble is dense and may go years between sealings; honed marble, travertine, and limestone absorb faster and are usually resealed every one to three years, kitchen counters more often than bathroom vanities. The sealer types and the grout side of the question are in grout sealing explained.
Etch or stain: telling them apart and fixing each
They’re opposites. An etch is a dull, lighter spot where acid has dissolved a little of the polished surface — it’s physical damage, no cleaner removes it, and the fix is repolishing: a marble polishing powder for a light etch, a professional re-polish for anything deeper. A stain is a darker spot where something was absorbed into the pores — oil, wine, rust — and the fix is drawing it back out with a poultice matched to the stain. A spot that is both dull and dark is both, and gets the stain treated first.
A routine that keeps stone right
Daily, dry-dust or dust-mop floors and wipe counters with a damp microfiber, because grit is what scratches polish. Weekly, clean with a pH-neutral stone cleaner and dry the surface so minerals in the water don’t spot it. Use coasters and trivets, wipe acidic spills immediately, and keep mats at entrances. Periodically — typically every one to two years — a professional deep clean and polish resets the sheen and is the moment to reseal. Routine care for stone floors and showers, including the coastal and hard-water factors that speed wear across the region, is covered in natural stone tile care.
Common questions
Is vinegar safe on marble?
No. Vinegar is acidic and etches marble, travertine, limestone, and onyx on contact. The same goes for lemon, citrus cleaners, and most bathroom sprays.
Can I use baking soda or a scouring powder on stone?
No. Both are abrasive and baking soda is alkaline; either dulls a polished surface. Use a pH-neutral stone cleaner and a soft cloth.
Is dish soap safe for natural stone?
A drop of mild dish soap in warm water is fine for routine wiping, but rinse and dry — soap left behind builds a film that dulls polish and attracts dirt.
How do I remove etch marks from marble?
Light etches respond to a marble polishing powder worked in a small circle; deeper or widespread etching needs professional re-polishing. Cleaners won’t remove an etch because it isn’t dirt.
How often should natural stone be resealed?
When the water test fails — typically every one to three years for honed marble, travertine, and limestone, longer for dense polished marble and granite.
