Solvent cleaning is used primarily to remove oil, grease, dirt, soil, drawing compounds and other similar organic compounds. Solvent cleaning may also be used to remove old paint by the use of paint removers or alkaline paint strippers. Inorganic compounds such as chlorides, sulfates, weld flux, rust and mill scale are not removed by cleaning with organic solvents.
