Phosphoric acid (85%)/1 Mix the solvent with the "Igepal" CO-730. Add the phosphoric acid with stirring. These formulations, diluted (1:40 to 1:50) with hot watr (120 to 140'F), will readily remove the alkali-resistant, acid-sensitive polishes. use in a manner similar to that employed with ordinary alkaline-based wax strippers. For example, apply the hot solution of diluted stripper to the floor. With brushes or stripping machines, work the stripping solution into the polish film. The film readily disintegrates. Mop up the residue without allowing the floor to dry. Rinse the floor thoroughly with warm watr and mop dry. One gallon of dilute stripper will remove approximately 500 sq. of old polish.
