There are two cases, one is on the surface of stone, which can be treated with household cleaner. Another is that the oil has penetrated into the stone, so it can't be scrubbed off. You can choose adsorption stone deoiling paste SINO3 10 for cleaning. Use a brush or scraper to coat the oil-absorbing paste on the surface of the substrate to be treated, with a thickness of 3-4 mm, and cover it with plastic wrap. The reaction can be left for up to 24 hours, based on the fact that the oil-absorbing paste is dry, crushed into powder, and then washed.
