ACIDIC CLEANING COMPOSITIONS

摘要

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.
