Abstract
The present invention is a non-corrosive, low-fuming oven cleaning composition that can be used easily on vertical oven surfaces. The present invention is a cleaning composition containing a tripolyphosphate and a thickening agent to promote in adherence to vertical surfaces.
Claims35
A method of cleaning a hard surface, said method comprising:
- spraying a non-corrosive, low-fuming composition having a viscosity ranging from about 30 to about 70 Cps at 25° C. onto the surface, said composition comprising:
- (a) from about 3.0 wt-% to about 20.0 wt-% of at least one detergent builder selected from tripolyphosphates;
- (b) from about 0.1 wt-% to about 20 wt-% of an alkalinity source effective to provide a pH of from about 10 to about 14 to said composition;
- c) from about 0.0 wt-% to about 5.0 wt-% of at least one thickening agent to promote adhesion of said thickened, non-corrosive composition to the surface upon application;
- d) from about 0.0 wt-% to about 5 wt-% of fatty acid stabilizer to maintain a homogenous mixture of said at least one detergent builder, at least one thickening agent, and alkalinity source;
- e) from about 0.0 wt-% to about 5.0 wt-% of an anionic surfactant effective to provide detergency to the thickened, non-corrosive low-fuming composition said anionic surfactant selected from the group consisting of an alkyl sulfate, an alkyl sulfonate, a disulphonate compound, an alkyl ether sulfate, an alkyl ether sulfonate, an alkyl aryl sulfonate, and mixtures thereof;
- (f) from about 0.0 wt-% to about 2.0 wt-% of a metal ion chelator;
- and
- (g) a balance of water;
- wherein the composition is substantially free of chlorine.

A sprayable thickened hard surface cleaning composition comprising:
- (a) from about 0.1 wt-% to about 20.0 wt-% of at least one detergent builder selected from tripolyphosphates;
- salts of alkali metal borates, phosphates, carbonates and bicarbonates;
- and mixtures thereof;
- (b) from about 0.1 wt-% to about 5 wt-% of at least one thickening agent effective to provide increased viscosity;
- (c) from about 0.1 wt-% to about 3.0 wt-% of an alkali metal hydroxide to provide a pH of about 10 to about 14;
- (d) from about 0.5 wt-% to about 5.0 wt-% of an anionic surfactant to provide detergency to the composition;
- (e) from about 0.0 wt-% to about 5 wt-% of a fatty acid stabilizer effective to maintain a homogenous mixture of said at least one detergent builder, at least one thickening agent, and alkali metal hydroxide;
- (f) from about 0.0 wt-% to about 2.0 wt-% of a metal ion chelator;
- and
- (g) a balance of water;
- wherein said composition is substantially free of chlorine and has a viscosity ranging from about 30 to about 70 Cps. at 25° C.
