Abstract (en)
[origin: EP0758017A1] Compositions are described which are aqueous cleaning compositions for removing limescale on hard surfaces which comprise maleic acid, an acid which has a first pKa not exceeding 5, or mixtures thereof, and an acid-stable thickener. Said compositions exhibit improved limescale removal performance and improved surface safety when used to treat hard-surfaces. Said compositions are particularly suitable to be used for removing limescale in large appliances like automatic dish washers and washing machines.
