Abstract
A polyacrylic resin which can be a polyacrylic acid or a mixture of a polyacrylic acid and an acrylic polymeric complex with a phosphinate or sulfur containing moiety is used as a builder in an aqueous glass cleaning composition of the spray-on wipe-off type containing an organic solvent system and at least one detergent surface active agent. Cleaning efficiency is comparable to and even superior to tetrasodium pyrophosphate built compositions.
