- (f) from about 30-85%, by weight, water; said liquid detergemt composition being substantially free of cross-linked polyacrylate polymers.
- 13. A method according to claim 12 wherein said nonionic detergent compound is a water-soluble C.sub.2 -C.sub.3 alkoxylated C.sub.10 -C.sub.18 alkanol.
- 14. A method according to claim 12 wherein said composition contains less than about 5%, by weight, of a surface active anionic detergent compound.
- 15. A method according to claim 12 wherin said composition is substantially free of a C.sub.10 -C.sub.18 alkyl benzene sulfonate anionic detergent.
- 16. A method according to claim 12 wherein said boron compound is an alkali metal borate.
- 17. A method according to claim 16 wherein said composition contains from about 3 to 7%, by weight, of said glycerine and from about 1 to 4%, by weight, of said alkali metal borate.
- 18. A method according to claim 12 wherein said alkali metal borate is borax.
- 19. A method according to claim 12 wherein said non-phosphate builder salt is present in the composition in an amount of from about 10 to 20%, by weight.
