DeSalin C is a special cleaner, based on a concentrated, natural acid. It is an eﬀective formulation for removing residues from cement surfaces, mortar, grout, stucco, natural or artiﬁcial stones. It is ideal for the removal of salt deposits, created due to eﬄorescence. Mould and mildew can also be succes-fully removed. Suitable for food production, as residues do not remain on the surface (thorough rinsing with water is required). Readily biodegradable formulation, without organic surfactants.
