Stone care & repair
Coffee stains: how to fix them on every surface
Coffee and tea contain tannins, brown plant pigments that soak into porous stone and set quickly. Coffee is also mildly acidic, so on marble, travertine and limestone a coffee ring can be a stain and an etch at the same time. How you remove it depends entirely on whether your surface is porous.
Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.

Every surface compared
| Surface | What is different on this surface | Difficulty | |
|---|---|---|---|
| Marble | On white marble such as Calacatta and Carrara, coffee usually leaves two marks at once: a brown tannin ring and a faint dull ring inside it where the acid in the coffee has etched the polish. | Easy to moderate | Read fix |
| Travertine | Coffee is the most common stain on travertine coffee and dining tables. The tannins soak into the stone and the filled holes at different rates, so a ring can look uneven. Treat the whole ring, not just the darkest part, and check the fills once the poultice comes off. | Easy to moderate | Read fix |
| Limestone | Limestone often needs two or three poultice rounds for coffee because the stain sits deeper than in marble. Each round should leave it noticeably lighter. | Easy to moderate | Read fix |
| Onyx | Coffee on an onyx bar or table is easy to see with the backlight on. Onyx is soft and often resin-backed, so keep poultices gentle and short, and leave anything stubborn to a restorer. | Easy to moderate | Read fix |
| Dolomite | Dolomite resists coffee's acidity better than marble, so a quickly wiped cup often leaves no etch at all. The brown tannin ring is the part that usually needs the poultice. | Easy to moderate | Read fix |
| Granite | Coffee rarely stains dark granite, but light granites such as Kashmir White are porous enough to take a brown ring overnight, especially beside the kettle. | Easy to moderate | Read fix |
| Quartzite | Coffee rings on quartzite usually appear in the more porous veins or patches of a slab rather than evenly across it, a sign the rest of the stone is dense. | Easy to moderate | Read fix |
| Quartz | Coffee almost never penetrates quartz. If a ring will not wipe off, it is usually dried residue, and a non-abrasive cream cleaner will lift it. | Easy | Read fix |
| Porcelain | On matte porcelain, dried coffee can sit in the fine surface texture and look like a stain. A soft brush with the cream cleaner reaches into the texture. | Easy | Read fix |
| Terrazzo | On terrazzo, coffee tends to stain the cement binder around the chips rather than the chips themselves, leaving a brown halo. | Easy to moderate | Read fix |
| Concrete | On concrete, a coffee ring usually means the sealer has worn through at that spot. If rings keep appearing in the same area, the surface needs refinishing or protecting. | Easy to moderate | Read fix |
| Soapstone | Soapstone will not take a coffee stain, but milky coffee can leave a darker oily spot. It disappears into the colour the next time the top is oiled. | Easy | Read fix |
Rules that apply to every surface
- Act fast. The sooner you blot or wipe, the less there is to fix.
- Test first. Try any method on a hidden spot and check once it is dry.
- No acids on calcite. Vinegar, lemon and most descalers etch marble, travertine, limestone and onyx.
- Protect after repair. A clear film stops the same mark happening again.
Frequently asked questions
Porous and acid-sensitive stones such as marble, travertine, limestone, onyx need the most care. Non-porous surfaces like porcelain and quartz are usually the easiest.
Always. Try any chemical or poultice on a hidden spot, such as inside a sink cut-out or under an overhang, and check the finish once dry.
A clear protection film over the surface keeps spills and acids off the stone. Stone Film Sydney installs it across Sydney with a 10-year warranty.
