Disclosed is a method of removing limescale and soap scum from a surface comprising: (i) applying a cleaning composition to a surface selected from the group consisting of a shower, a bath tub, and a sink, and (ii) rinsing the cleaning composition from the surface, wherein the cleaning composition comprises: (A) a hydrophilizing polymer, wherein the hydrophilizing polymer is a water soluble or water dispersible copolymer comprising a reaction product of: (a) at least one monomer having the following structure (I) wherein R1 and R4 independently represent a hydrogen atom or an alkyl group; R2 and R3 independently represent an alkyl, hydroxyalkyl or amino alkyl group and m independently represent integers between 1 and 3; X" represents a counterion; and (b) at least one hydrophilic monomer having an acidic function which is copolymerizable with (a) and capable of ionizing in the medium of use; and wherein the molar ratio of monomers (a)/(b) is from about 60/40 to about 5/95, (B) a surfactant, and (C) an acid. Also disclosed is the cleaning composition used in the method.
