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 sits in the surface of porcelain rather than soaking in. Wash with warm soapy water, then gently work a paste of bicarb soda and water or a non-abrasive cream cleaner over the yellow mark and rinse. 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
- Bright yellow mark after cooking: turmeric or curry.
- Yellowing that is brownish and near the cooktop: possibly heat scorching instead. See the heat marks guide.
What you need
- Dish liquid
- Bicarb soda or non-abrasive cream cleaner
- Soft cloth
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 porcelain.
Gently lift the colour
Make a paste of bicarb soda and water (or use a non-abrasive cream cleaner), rub gently in small circles for a minute, then rinse and dry.
Let the sun help

What not to use on porcelain
- Scourers, steel wool and abrasive creams on a polished surface.
- Mixing cleaning chemicals, especially bleach with anything else.
When to call a professional
A porcelain repairer can fill chips with colour-matched resin; scratches through the printed layer cannot be polished back.
Understanding turmeric and curry stains on porcelain
Porcelain is fired to a dense, non-porous body, so liquids stay on the surface and nearly all marks can be cleaned off.

Good to know
Turmeric on porcelain sits entirely on top. A cream cleaner removes it, and anything left fades in daylight.
