STON is an acid detergent free from inorganic mineral acids made specifically to clean soft stone; its acid strength acts on the surface without penetrating the material. STON specifically removes saltpeter patches, salt of limestone origin and grouting residue from surfaces and cleans limestone on sanitary ware and floors.
Any rough stone material and deteriorated stone. Ideal for floors, coatings and monuments since it is acid-resistant.
Dilute with 30% water or 1:1 according to the dirt and the material that is to be cleaned. Apply the compound on the surface, scrub with a brush or green, blue or white scouring pad. Leave for a few minutes and rinse.
