- (f) about 5-25% of a (C.sub.1 -C.sub.4)alkanol;
- (g) the balance water.
- 2. The glass cleaning solution of claim 1 wherein the copolymer is an ethylene-maleic anhydride copolymer.
- 3. The glass cleaning solution of claim 1 wherein the (C.sub.1 -C.sub.4)alkylene (C.sub.1 -C.sub.4)alkyl ether comprises propylene glycol monomethyl ether.
- 4. The glass cleaning solution of claim 1 which comprises about 0.1-1.0% of N-methyl-2-pyrrolidone.
- 5. The glass cleaning solution of claim 1 wherein the anionic surfactant comprises a fatty alcohol-polyethylenoxysulfate salt.
- 6. The glass cleaning solution of claim 1 wherein the (C.sub.1 -C.sub.4)lower alkanol comprises isopropanol.
- 7. The glass cleaning solution of claim 1 which has a pH of about 7.5-10.
- 8. The glass cleaning solution of claim 7 which comprises an amount of an alkanol amine effective to adjust the pH of the solution to about 8-9.75.
- 9. The glass cleaning solution of claim 8 which comprises about 0.05-0.75% of triethanol amine.
- 10. The glass cleaning solution of claim 1 which comprises an effective amount of a glycol plasticizer.
- 11. The glass cleaning solution of claim 10 which comprises about 0.1-1.0% of propylene glycol or ethylene glycol.
- 12. A glass cleaning solution comprising:
- (a) about 10-35% of an aqueous solution of about 0.25-1.0% ethylene-maleic anhydride copolymer and an amount of a basic compound effective to solubilize said copolymer;
- (b) about 0.04-0.25% of poly(acrylamidomethylpropane) sulfonic acid;
- (c) about 0.01-0.3% of an anionic sulfonate or sulfate surfactant;
- (d) about 0.05-1.0% of a (C.sub.1 -C.sub.4)alkylene glycol (C.sub.1 -C.sub.4)alkyl ether;
- (e) 5-25% of a (C.sub.1 -C.sub.4)lower alkanol; and
- (f) the balance water, wherein the pH of said glass cleaning solution is adjusted to about 8-9.5.
- 13. The glass cleaning solution of claim 12 wherein the pH of the solution is adjusted by the addition of about 0.05-0.75% triethanol amine.
- 14. The glass cleaning solution of claim 12 wherein the basic compound is ammonia.
- 15. An applicator for cleaning glass surfaces comprising a porous substrate impregnated with an effective amount of the glass cleaning solution of claims 1 or 12.
- 16. The applicator of claim 15 wherein the porous substrate comprises a nonwoven cellulosic sheet.
- 17. The applicator of claim 15 which is packaged in a moisture-resistant container.
