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
Porcelain is acid-resistant, so limescale comes off with an ordinary bathroom descaler or a 50:50 mix of white vinegar and water. Leave it a few minutes, wipe, rinse and dry.
First, check what you are dealing with
- White crust around taps: limescale.
What you need
- White vinegar or descaler
- Microfibre cloth
Step by step
Apply
Wipe on a 50:50 vinegar and water mix, or a descaler, over the scale.
Wait
Leave three to five minutes to dissolve the minerals.
Rinse and dry
Rinse with clean water and dry.
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.
