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
Coffee rarely soaks into porcelain because it is non-porous, so the mark sits on the surface. Wipe with warm soapy water, then use a non-abrasive cream cleaner for anything left. No poultice is needed.
First, check what you are dealing with
- Brown residue you can feel or see on top: dried coffee. Clean it off.
- A faint yellowish tint after cleaning: a stain in the surface. Use the cream cleaner step and give it time.
What you need
- Warm water
- pH-neutral dish liquid
- Soft cloth or sponge
- Non-abrasive cream cleaner
Step by step
Blot, do not wipe
Soak up any liquid with paper towel straight away. Wiping spreads it across a bigger area.
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.
Lift what is left
Apply a little non-abrasive cream cleaner with a damp soft cloth, work it gently in small circles for a minute, then rinse and dry.
Check in daylight
Look at the area in natural light. It should now match the rest of the surface.
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
If a mark will not shift after gentle cleaning, ask a repairer before trying anything stronger. A porcelain repairer can fill chips with colour-matched resin; scratches through the printed layer cannot be polished back.
Understanding coffee 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
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.
