Abstract
Stripping solution compositions which avoid the problem know as 'brown staining' are provided. Relevant stripping solutions are those that are free from phenol and chlorinated hydrocarbon compounds and comprise a surfactant alkylarylsulfonic acid having 12-20 carbons, a hydrotropic aromatic sulfonic acid having 6-9 carbons and a halogen-free aromatic hydrocarbon solvent with a boiling point above 150.degree. C. To suppress brown staining, a water soluble sulfone is incorporated into the stripping solution. The stripping compositions effectively remove organic polymeric substances from inorganic substrates and are substantially clear water rinsable.
