摘要：
A cleaning composition for a hard surface is disclosed which provides for initial cleaning of the hard surface and provision of a hydrophilic coating or barrier layer on the surface which provides residual cleaning to the hard surface for an extended number of rinsings. The composition includes a hydrophilic polymer, at least one nonionic surfactant, at least one solvent, an acid and water, wherein the acid provides the composition with a pH of about 2 to 3.5 and the composition is provided in the absence of any anionic, cationic or amphoteric surfactant.
