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
Oil sits on the surface of porcelain because it is non-porous. Wipe with hot water and dish liquid, then dry. For a stubborn greasy film, use a degreaser or non-abrasive cream cleaner.
First, check what you are dealing with
- Greasy film or smear: surface oil. Clean it off.
- Dull patch that persists: residue build-up, or chemical damage if a harsh degreaser was used.
What you need
- Hot water
- Dish liquid
- Microfibre cloth
- Non-abrasive cream cleaner
Step by step
Wash with hot soapy water
Hot water and a good squeeze of dish liquid dissolves most cooking oil.
Degrease stubborn areas
Work a non-abrasive cream cleaner over any remaining film.
Rinse and dry
Rinse with clean water and dry with microfibre so no streaky film is left.
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 oil and grease 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
Porcelain cannot absorb oil. A greasy film is residue, and on matte porcelain it can make the surface look darker in patches until degreased.
