If your soapstone sink sees any use, it will eventually get dirty. Fortunately, soapstone is a durable material and is easy to clean. By using these techniques, you can keep your soapstone stain free.
Step 1 - Setting Up
Soapstone will stand up to a mild non-abrasive cleaner, but usually, just using soap and water will do just fine. To begin, mix a few drops of ordinary dish soap into a bucket of warm water. Stir the ingredients together until they form a lather.
Step 2 - Cleaning the Soapstone Sink
Dip your sponge into the mixture of warm water and dish soap. Use the sponge to apply the mixture to your sink. You can scrub your sink relatively hard as long as you do not use an abrasive pad. Focus your efforts on stains, discolorations, and grime. You should be able to remove them completely with this simple mixture and a little bit of work. Once you have finished, rinse away the soapy water.
Step 3 - Dealing With Tough Stains
Sometimes, your soapstone sink will have stains that cannot be removed by scrubbing with soapy water. In such situations, you can use mineral oil by pouring it onto a clean cloth and rubbing it over the soapstone. Cover the surface with a layer of oil and let it seep into the surface.
In extreme cases, you can use a strong paint stripper, but only after doing a test patch first. Apply a small amount to the stain with a cloth, then wait a few minutes before wiping it away.
