Abstract
The present disclosure relates to a concentrated acidic floor cleaner and methods of using it to clean floors. The concentrated acidic floor cleaner can be diluted to form a use solution that is effective at removing polymerized grease, including animal and vegetable fats and non-trans fats, and other soils from floors. The use solution is especially useful for cleaning floors in commercial kitchens of full service and quick service restaurants and is effective on a variety of floors, including quarry tile.

A method of cleaning floors comprising:
- (A) forming a use solution by mixing water and from about 1 to about 0.5 ounces per gallon of water of a concentrated acidic cleaner, the concentrated acidic cleaner consisting of:
- (i) from about 1 to 60 wt.% of acid selected from the group consisting of citric, isocitric, tartaric, malic, monohydroxyacetic, acetic, gluconic and salts and mixtures thereof;
- (ii) from about 0 to about 80 wt.% of a buffering salt;
- (iii) from about 0 to about 40 wt.% of a surfactant;
- (iv) amine;
- and
- (v) caustic
- wherein the concentrated acidic cleaner has ratio of total acid to free acid of at least 2.5:1 and
- (B) applying the use solution to a floor.
