The #87 Degreaser Solution is a highly concentrated liquid cleaner and degreaser used for cleaning glass, plastic, metal, and other substrates. It has been shown to erase hard-to-remove oils, organic residues, and fingerprints from various surfaces. The #87 cleaner is a strong industrial solution that can clean surfaces before or after applying Permalac. It can be used to prepare the surface for optimal adhesion or clean up substrates coated with Permalac without worrying about disturbing the lacquer finish or causing visible streak marks, which other cleaners may sometimes produce.
