Alcohol General Information Alcohols are commonly used as drying agents for intricate assemblies. Methanol and isopropanol have fair degreasing capabilities. Methanol is incompatible with Viton®. With brief exposure, isopropanol is compatible with most elastomers. Isopropanol is commonly used as a wipe solvent in precision cleaning. Alcohols are not good for removal of nonpolar soils, e.g., waxes and oils. Alcohols are incompatible with many polymers and elastomers and are photochemically reactive. Isopropanol (IPA) may be used in an azeotrope of 88% IPA and 12% water. This azeotrope has a boiling point of 178 ° F; IPA is a flammable liquid at 65 ° F.
