What you'll need
- Liquid dish soap
- Bucket
- Warm water
- Sponge
- 2 cleaning cloths
- 2 dry towels
- Mineral oil
Step 1 - Cleaning
While filling the bucket with warm water, add a couple drops of dish soap so it will begin to foam. Do not use too much as the soap film which can be left will dull the floors. Apply the soapy water to the tiles in areas of 2 by 4 feet. The water will not seep in, creating very slick floors. Be careful. Wipe any soapy residue away with a thoroughly wet sponge. Dry with a towel.
Step 2 - Maintenance
Apply a couple drops of mineral oil to a clean, dry cloth. Wipe the oil onto the soap stone tiles. The oils will not seep in—soapstone is non-porous. Use a dry towel to wipe away any excess oils so the surface does not feel slick. Apply the mineral oil every 2 weeks for the initial year in order for the stone to oxidize evenly. In subsequent years, every 2 months is good.
