Abstract
Removal of water-insoluble organic residues from inorganic surfaces can be accomplished in aqueous cleaning solutions containing an oxidant at a preselected temperature wherein the pH is adjusted with respect to the isoelectric point of the surface material to be removed so that the pH is above the pK, and the isoelectric point of the surface for acid materials, and below the PKa and the isoelectric point of the surface for basic materials. Surfactants can also be added to the cleaning solution.
