- (d) 0.1 to 15% of a magnesium salt; and
- (e) the balance being water wherein said composition does not contain any anionic polymer, cationic polymer, cationic disinfectant or benzalkonium chloride.
- 8. The cleaning composition of claim 1 wherein the glycol ether is selected from the group consisting of ethylene glycol monobutylether, diethylene glycol monobutyl ether, triethylene glycol monobutylether, and propylene glycol tert.butyl ether, mono, di, tri propylene glycol monobutyl ether.
- 9. The cleaning composition of claim 8 wherein the glycol ether is ethylene glycol monobutyl ether or diethylene glycol monobutyl ether.
- 10. A liquid detergent composition according to claim 7 wherein ethanol is present in the amount of 5% by weight or less.
- 11. A liquid detergent composition according to claim 7 wherein said anionic surfactant is selected from the group consisting of C.sub.12 -C.sub.16 alkyl sulfates, C.sub.10 -C.sub.15 alkylbenzene sulfonates, C.sub.13 -C.sub.17 paraffin sulfonates and C.sub.12 -C.sub.18 alpha olefin sulfonates.
- 12. The cleaning composition of claim 1 wherein the anionic surfactant is a C.sub.9 -C.sub.15 alkyl benzene sulfonate or a C.sub.10 -C.sub.20 alkane sulfonate.
- 13. A liquid detergent composition according to claim 7 wherein said anionic detergent is a C.sub.12 -C.sub.16 alkyl sulfate.
- 14. An all purpose hard surface cleaning composition which having a pH of 7.0.+-.1.5 consists essentially of approximately by weight:
- (a) 1 to 30% of at least one anionic surfactant, one of said anionic surfactants being an anionic surfactant;
- (b) 0.1 to 10% of a grease release agent which is a polyethylene glycol which is complexed with said anionic surfactant;
- (c) 0.1 to 5% of a magnesium containing inorganic compound;
- (d) 1 to 15% of a cosurfactant, which is a monoalkyl ether or ester of ethylene glycol or propylene glycol; and
- (e) the balance being water wherein said composition does not contain any anionic polymer, cationic polymer, cationic disinfectant or benzalkonium chloride.
- 15. An all purpose hard surface cleaning composition according to claim 7, wherein said magnesium containing inorganic compound is magnesium sulfate heptahydrate.
