A unique, multifunction cleaner easily removes dirt and stains on bahroom fittings, glazed surfaces, terracotta, shower cabins and plastic surfaces not scratching the cleaned surfaces. Its active ingredients perfectly cope with soap scum, waterstains, greasy stains and other dirt, and the unique polishing and protective agents give a beautiful luster to bathroom fittings and ceramics. The silica nanoparticles, contained in the cleaner, penetrate the tiniest unevenness of the structure separating particles of dirt from the surface being cleaned.
