Abstract
A cleaning solution comprising a water-alcohol mixture, an anionic surfactant, a glycol ether, an anionic polysulfonic acid and an anhydride compound comprising an olefin-maleic anhydride copolymer, a monomeric cyclic anhydride or mixtures thereof, is disclosed which is employed to impregnate absorbent substrates to prepare applicators useful for cleaning glass surfaces.

A glass cleaning solution comprising:
- (a) an anhydride compound selected from the group consisting of about 0.03-0.25% of a co-polymer derived from (1) a maleic anhydride of the formula:
- ##STR2## wherein R and R.sub.1 are independently selected from the group consisting of H, (C.sub.1 -C.sub.4)alkyl, phenyl, (C.sub.1 -C.sub.4)alkylphenyl, phenyl(C.sub.1 -C.sub.4)alkylene and (2) a (C.sub.1 -C.sub.4)olefin;
- (b) an amount of ammonia or an amine effective to solubilize said anhydride compound;
- (c) about 0.025-0.5% of poly(2-acrylamido-2-methyl propane) sulfonic acid;
- (d) an effective amount of an anionic surfactant;
- (e) an effective grease-solubilizing amount of a (C.sub.1 -C.sub.4)alkylene (C.sub.1 -C.sub.4)alkyl ether or a (C.sub.1 -C.sub.4)dialkylene (C.sub.1 -C.sub.4)alkyl ether;
- (f) about 5-25% of a (C.sub.1 -C.sub.4)alkanol;
- (g) the balance water.
