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 not meant to be glossy; what brings back its depth is oil. Clean the top, then wipe on a thin, even coat of food-grade mineral oil, leave it 30 minutes and buff off the excess. The colour deepens to a rich charcoal.

First, check what you are dealing with

  • Pale, dry-looking top: needs oiling.
  • Patchy colour: oil the whole surface evenly.

What you need

  • Food-grade mineral oil
  • Lint-free cloths

Step by step

  1. Degrease first

    Wash with hot water and a good squeeze of dish liquid, rinse with clean water and dry with microfibre. Residue from oils and cleaners is the most common cause of a flat-looking surface.

  2. Oil evenly

    Apply a thin coat of mineral oil to the entire top.

  3. Buff

    After 30 minutes, buff off the excess.

What not to use on soapstone

  • Stone polishes and waxes made for marble.

When to call a professional

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

Understanding dull surfaces and lost shine on soapstone

On soapstone, marks show as lighter scratches, dents, and uneven darker patches where oils have soaked into the surface.

Good to know

Soapstone is not meant to be shiny. What owners usually want is depth of colour, and that comes from an even coat of mineral oil.

Stop it happening again

Whether yours is benchtop-grade steatite, usually charcoal or grey-green, repairing it fixes today's mark; protecting it stops the next one. Our clear Stone Protection Film sits over the surface, so marks stay on the film, not the surface, and its self-healing top layer shrugs off fine everyday marks. Most soapstone is honed and oiled, so the Matte/Satin film is the usual match: it keeps the natural, low-sheen look. It is installed across Sydney with a 10-year written warranty.
