- 15. A cleaning composition according to claim 4 which additionally comprises from about 0.5% to about 15% by weight of an anti-corrosive agent.
- 16. A cleaning composition according to claim 15 wherein the anti-corrosive agent comprises:(a) a surfactant other than an alkyl acid phosphate; (b) at least one alkyl acid phosphate, in a surfactant-phosphate weight ratio in the range between 10:1 and 1:10, said phosphate having the general formula: wherein R is an alkyl group having 4 to 20 carbon atoms; m is 1 or 2; and n is 3-m.
- 17. A cleaning composition according to claim 16 wherein said phosphate is amine-neutralized with a tertiary amine.
- 18. A cleaning composition according to claim 17 wherein the anti-corrosive agent also contains from about 5% to about 40% by weight, based on the combined weight of said surfactant and said phosphate, of at least one carboxylic acid which has both a hydrophilic and hydrophobic portion.
- 19. A cleaning composition according to claim 15 wherein the anti-corrosive agent comprises:(a) from about 70% to about 80% by weight a nitrogen and sulfur-containing aryl heterocycle; and (b) from about 20% to about 30%, by weight, of an alkanolamine.
- 20. A cleaning composition according to claim 19 wherein the alkanolamine is triethanolamine.
- 21. A cleaning composition according to claim 20 wherein the aryl heterocycle is 10-H-phenothiazine.
- 22. A method for cleaning fabrics comprising the agitation of said fabrics in an aqueous solution comprising from about 0.25% to about 5% by weight of the cleaning composition of claim 1.
- 23. A method for cleaning hard surfaces comprising contacting said surfaces with an aqueous solution comprising from about 0.02% to about 5% by weight of the cleaning composition of claim 1.
