DeSalin SG is a special cleaner, developed for treating eﬄorescence deposits on porous surfaces like ceramic bricks, roof tiles, stones or other absorptive surfaces. DeSalin SG acts as a salt grabber: Its ingredients exhibit high chemical aﬃnity to metal cations. The resulting reaction products are highly water soluble; thus salts get eliminated from the porous surface. Chemical aﬃnity is even more expressed in the cases of calcium (Ca2+) and magnesium (Mg2+), which are most often responsible for the hardest deposits to clean. In combina-tion with SurfaPore C the penetration of humidity or water content in the mass of the clay/stone mass is blocked and protection is enhanced.
