An outside window cleaner comprising mixtures of one or more polyvinyl alcohols with water, or preferably, polyvinyl alcohol, a cationic polymer, such as trimethylol melamine, and water, alters or modifies window or other hard surfaces such that water drains off in uniform sheets, leaving virtually no residue or spots caused from the deposition of dirt, cleaning compositions or a combination of the two. In a further embodiment, a selected cationic or nonionic surfactant is added to the formula of this invention to improve detergency while retaining the uniform drainage advantage in rinsing.
