Soapstone countertops are easy to polish or oil. When the previous oil coating starts to lighten, it means that the mineral oil has evaporated. This is a good time to apply oil again to your soapstone countertop. Then again, you can oil soapstone countertops as often as you want.
Oiling is done to hasten its natural darkening process. Soapstone does not need to be sealed, because it is non-porous, unlike granite and marble.
Step 1 - Pour Mineral Oil
Pour a moderate amount of mineral oil on your countertop, or dampen the cloth with oil. Too little or too much oil has no side effects, so don’t worry about measurements.
Step 2 - Wipe
Spread the oil using the cloth. Notice that once you’ve applied the oil, the stone starts to darken to a dark gray, and sometimes even black.
Step 3 - Remove Excess
Since soapstone is not porous, you don’t have to think of anything like letting the oil sink in. Dry the countertop of excess oil. Wipe it completely, and do not leave any greasy feel.
Step 4 - Keep Your Cloth
Store your cloth in a plastic bag, and use it the next time you need to oil your countertop. This is advisable because a cloth that is already saturated with mineral oil is a better polisher for soapstone countertops.
