Parts Washers Proper management of parts washer waste depends on the type of cleaning solution you use and what you are cleaning. Available cleaners include solvent, aqueous and semi-aqueous solutions. Never put parts washer cleaning solution down the drain. Some vendors provide a service that includes lease of a parts washer and regular disposal of the cleaning solution. Alternatively, you can buy the parts washer and cleaning solution separately and arrange for proper disposal yourself.
Most parts washers have a filter that is periodically replaced.
