Abstract
The present invention provides for the use of activator complexes to enhance lower temperature cleaning in alkaline peroxide cleaning systems. Compositions including at least one of an activator complex, an active oxygen source, and a source of alkalinity are applied to the surface to be cleaned at temperatures between about 5° C. and about 50° C. The methods and compositions of the present invention provide for enhanced soil removal with reduced energy, water, and chemistry consumption.
Claims8
A method for removing soil from a surface in an industrial process, comprising:
- (i) preparing an activated use solution, comprising:
- adding an amount of an activator composition to an active oxygen source composition, wherein the activator composition catalyzes the production of oxygen gas, the activator composition comprising:
- 10-30 wt % alkali metal hydroxide, 0.1-10 wt % Fe gluconate or Mn gluconate, and water, wherein the Fe and Mn remain in solution in the presence of the alkali metal hydroxide;
- and
- (ii) applying the activated use solution to a soiled surface at a temperature of between about 5 to about 50 degrees C. in a clean in place process, wherein the oxygen gas mechanically breaks up soils on the surface.
