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

Soapstone is chemically inert, so a 50:50 mix of white vinegar and water dissolves limescale without harming it. Wipe it on, leave a few minutes, rinse, dry, and re-oil the area if it looks lighter.

First, check what you are dealing with

  • White crust around taps: limescale.

What you need

  • White vinegar or descaler
  • Microfibre cloth
  • Mineral oil

Step by step

  1. Apply

    Wipe on a 50:50 vinegar and water mix, or a descaler, over the scale.

  2. Wait

    Leave three to five minutes to dissolve the minerals.

  3. Rinse and dry

    Rinse with clean water and dry, then re-oil if the area looks lighter.

What not to use on soapstone

  • Scourers, steel wool and abrasive creams on a polished surface.
  • Mixing cleaning chemicals, especially bleach with anything else.

When to call a professional

Most soapstone repairs are DIY: fine sandpaper and mineral oil. A stonemason can smooth chipped edges.
