Kitchen utensils, especially knives, can scratch the kitchen counter whatever the type of surface material. This is why a cutting board is always recommended. But mishaps can occur, particularly in a busy kitchen, and there are simple methods to restore a soapstone surface:
1. Sand the area with 150 grit sandpaper the same way you would sand a piece of pine.
2. Wipe the area clean with a wet rag and allow it to dry.
3. Once dry, use a rag and wipe the entire area with mineral oil (More about mineral oil below). If the scratch is small try wiping it with the mineral oil first, that may do the trick.
4. You are done!
Mineral oil can be purchased at any pharmacy. When your counter is newly installed, it will receive its first coat. Thereafter, we recommend wiping the counters twice a week for the first four weeks and then once every year. To oil an entire kitchen will take about 15 minutes. Mineral oil is perfectly safe.
You can clean your counters any way you choose - the stone is non-porous.
