Abstract
The present invention relates to compositions and methods for removing soils, e.g., thermally degraded food soils, from surfaces. The cleaning compositions of the present invention can be activated using heat and/or an activator complex to generate oxygen gas in situ on and in the soil to be removed. Surfaces suitable for cleaning using the compositions and methods of the present invention include any surface that can be heated during use and/or cleaning, e.g., smokers, ovens, fryers.
Claims25
A method for removing soil from a hard surface comprising:
- (a) manually applying a cleaning composition to the surface, the cleaning composition comprising:
- an active oxygen source;
- a source of alkalinity;
- and about 0.1 wt % to about 4 wt % of a thickening agent, wherein the composition is stable for about 4 to about 72 hours at room temperature, and has a cling time of about 0.1 minutes to about 60 minutes;
- (b) activating the composition to generate oxygen gas on and in the soil;
- and
- (c) removing the composition from the surface after an amount of time sufficient to facilitate soil removal.

A method for removing a food soil from a hard surface comprising:
- (a) heating the surface to about 160° F. to about 210° F.;
- (b) manually applying a cleaning composition having a cling time of at least about 0.1 minutes to about 60 minutes to the surface, the composition comprising a peroxygen compound, an alkaline detergent, and about 0.1 wt % to about 4.0 wt % of a thickening agent, wherein the composition is stable for about 4 to about 72 hours at room temperature;
- (c) removing the composition from the surface after an amount of time sufficient to facilitate soil removal;
- and
- (d) rinsing the surface.
A method for removing a food soil from a hard surface comprising:
- (a) contacting the surface with an activator complex;
- (b) manually applying a cleaning composition having a cling time of at least about 0.1 minutes to about 60 minutes to the surface, wherein the composition comprises a peroxygen compound, an alkaline detergent composition, and about 0.1 wt % to about 4.0 wt % of a thickening agent, wherein the composition is stable for about 4 to about 72 hours at room temperature;
- (c) heating the surface to about 120° F. to about 210° F.;
- (d) removing the composition from the surface after an amount of time sufficient to facilitate soil removal;
- and
- (e) rinsing the surface.
