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
Light scratches on soapstone often vanish with a rub of food-grade mineral oil. Deeper ones sand out: work 220-grit sandpaper along the scratch (start with 120 or 80 for deep gouges, then step up), finish with 400-grit, then oil the whole area so the colour blends.
First, check what you are dealing with
- Light, pale line: surface scratch. Try oil first.
- Scratch you can catch a fingernail in: sand it out.
- Dent or chip: see the chips guide.
What you need
- Food-grade mineral oil
- Sandpaper: 120, 220 and 400 grit
- Sanding block
- Lint-free cloths
Step by step
Try oil first
Rub mineral oil into the scratch. Light scratches often disappear as the stone darkens.
Sand deeper scratches
Sand along the scratch with 220-grit (or coarser for deep gouges), feathering out past its edges.
Refine
Step up to 400-grit until the area feels as smooth as the rest of the top.
Oil to blend
Wipe away the dust and oil the whole surface so the sanded area matches.
What not to use on soapstone
- Power sanders, which can dish the surface.
- Oiling only the repaired spot.
When to call a professional
Most soapstone repairs are DIY: fine sandpaper and mineral oil. A stonemason can smooth chipped edges.
Understanding scratches on soapstone
Soapstone is rich in talc, the softest mineral, so it scratches and dents easily, but scratches can usually be sanded and oiled out at home.
On soapstone, marks show as lighter scratches, dents, and uneven darker patches where oils have soaked into the surface.

Good to know
Soapstone is the one stone where fixing scratches is genuinely a DIY job. Most light scratches disappear with a rub of mineral oil; deeper ones sand out.
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.
