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.
Quick answer
Turmeric stains in travertine come out with a hydrogen peroxide poultice: wipe up the spill, wash the area, then cover the yellow stain with the poultice for 24 to 48 hours. Curcumin, the yellow pigment in turmeric, fades under UV light, so a few days of direct sunlight on the stain often finishes the job.
First, check what you are dealing with
- Yellow or orange mark: turmeric or curry. Follow the steps below.
- Yellow mark with an oily halo: curry oil too. Do a solvent poultice after the peroxide.
What you need
- pH-neutral dish liquid
- Hydrogen peroxide
- Flour, talc or diatomaceous earth
- Plastic wrap and tape
- Plastic scraper
Step by step
Wash the area
Clean with warm water and a few drops of pH-neutral dish liquid, rinse and dry with a soft cloth so you can see what is left on the travertine.
Test first
Try the mixture on a hidden spot of your travertine (inside a cut-out or under an overhang) and check the finish after it dries.
Mix the poultice
Stir an absorbent powder (plain flour, talc, diatomaceous earth or whiting) into hydrogen peroxide (3% from a pharmacy for fresh stains, or 12% from a hairdressing or pool supplier for older ones) until it has the consistency of peanut butter.
Apply it
Spread it 5 to 6 mm thick over the yellow stain, extending about a centimetre past the edge. Cover any filled holes inside the stained area too: fills hold stains as well as the stone does.
Cover and wait
Cover with plastic wrap, tape the edges and poke a few small holes so it dries slowly. Leave it 24 to 48 hours until completely dry: the drying is what pulls the stain up into the powder.
Remove and rinse
Lift the dry poultice with a plastic scraper, rinse with clean water and dry the travertine. If the yellow stain is lighter but still there, repeat up to three times.
Let the sun help
Curcumin, the yellow pigment in turmeric, fades under UV light, so a few days of direct sunlight on the stain often finishes the job.
What not to use on travertine
- Vinegar, lemon juice or "natural" citrus cleaners: they etch travertine.
- Scourers, steel wool and abrasive creams on a polished surface.
- Mixing cleaning chemicals, especially bleach with anything else.
- Bleach, which can leave a pale patch in the stone.
When to call a professional
If a yellow shadow persists after poulticing and sunlight, a restorer can treat it. A stone restorer can refill open holes, re-hone the surface and blend repairs into the surrounding stone.
Understanding turmeric and curry stains on travertine
Travertine is full of natural cavities that are filled with resin or cement, and the stone between them is porous. Coffee, wine and oil soak in quickly, and fills can take stains differently from the stone.

Good to know
Turmeric on a travertine table often stains the fills more strongly than the stone, leaving bright yellow dots. Poultice the whole area and give it sunlight.
Stop it happening again
Whether yours is ivory, beige, walnut and silver travertine, vein cut or cross cut, repairing it fixes today's mark; protecting it stops the next one. Our clear Stone Protection Film sits over the surface, so acids cannot etch it and liquids cannot soak in. Most travertine is honed and filled, so the Matte/Satin film is the usual match: it keeps the natural, low-sheen look. It is installed across Sydney with a 10-year written warranty.
