As a “shock treatment” for extremely soiled floors, use full strength or at a 1:1 dilution with HOT water. Apply solution with mop or brush, agitating thoroughly. Allow solution to stand on floor surface for a few minutes, then re-agitate with brush or mop. Pick up soiled solution with mop or wet-vac. Rinse well and allow to dry. For economical daily maintenance, dilute from 2-6 oz. per gallon of water and mop floor in usual manner. Rinse well and allow to dry. This product is excellent for use in foam-generating equipment. Always rinse food contact surfaces with potable water before use.
