The removal of dried paint residues from difficultly accessible surfaces is substantially speeded up by using particulate solids, which are insoluble in conventional liquid solvent-swellant compositions for removing paint residues but are soluble in water, in the form of a slurry of the particulate solids in a conventional liquid cleaner composition for paint residues, contacting the paint residues with the slurry while it is maintained in turbulent motion, removing the slurry, and rinsing with water, so as to dissolve any remaining solids from the slurry that might later contaminate the cleaned surface.
