ABSTRACT:
A method for removing residues including waxes, oils, greases, resins, fluxes, diamond lapping compounds and solvent soluble resists from the surface of electronic components, optic elements, contact lenses and metals comprises the steps of contacting the surface with a solution consisting of from 60% to 100% of liquid n-paraffins, iso-paraffins or a mixture thereof having hydrocarbon chain lengths substantially in the range of from C.sub.9 to C.sub.16, from 0% to about 40% paraffin emulsifying agents and from 0% to about 25% d-limonene, allowing the solution to solubilize the residues and removing the solution from the surface.
