Abstract

Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent; water; sulfonic acid, sulfate acid, phosphonic acid, phosphate acid or aromatic acid coupler in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking; and sufficient organic amine so that the composition pH is about 2 to about 11.
