Cleaning compositions are disclosed that economically and effectively remove a variety of marking materials from many coated or uncoated substrate surfaces. The compositions contain a terpene compound, a pyrrolidone compound, an emulsifying surfactant, and water, the compositions being in the form of a microemulsion. Also disclosed are methods of cleaning marked surfaces with the microemulsion compositions.

Enzymatic detergent composition and method for degrading and removing

This invention relates to an enzymatic detergent drain cleaner composition comprising:

This invention relates to an enzymatic detergent drain cleaner composition containing: 0.015-20 wt % of an acid cellulase enzyme having hydrolytic activity specific to .beta.-glucosidic bonds; 1-70 wt % of a water soluble carbonate salt; 1-70 wt % of a water soluble acid that reacts in an aqueous medium with the carbonate salt to form carbon dioxide that dissolves in the aqueous medium; 0.1-10 wt % of a surfactant; and 0.05-5 wt % of a thickening agent. This detergent composition may be used as an enzymatic detergent drain cleaner or in a method for removing or preventing bacterial cellulose deposits in an aqueous system at a solution temperature of up to about 60.degree. C. and a pH of about 2 to about 7.

A method of removing from a stainless steel surface a difficultly removable soil originating from an animal or vegetable source comprising the step of contacting the soil adhered to the surface with an amount of a noncorrosive chemical composition effective to ultimately essentially chemically remove the soil from at least 51% of the surface. The difficultly removable soils that can be removed by the method of the invention are otherwise ultimately essentially chemically removable from at least 51% of the surface, at the temperature at which the above contacting step is conducted, only by contact with at least one corrosive chemical composition. The method is both safe for the user and highly effective to remove the above-described soils.
