Founded in 1939, Graymills Corporation has become a leading U.S. manufacturer of parts washers, coolant tanks and centrifugal pumps. A small women-owned business located in Chicago, Illinois, we have recently focused on aircraft cleaning needs with multiple processes, custom-built to fit parts and specific contaminants. From front and top load spray cabinets to immersion units, we have worked with Army, Navy and Air Force units to clean wheels, engine parts and general equipment.

Our products are built to last, developed to withstand the roughest treatment. We manufacture parts washers/degreasers and cleaning fluids, filtration and fluid treatment systems for industrial, automotive, aircraft maintenance manufacturing and service applications. Offering bench-top to large tank solvent and aqueous washers, we specialize in immersion units with or without lift agitation, and high-powered pump turbo action units. We also provide jet-spray cabinets, bio-based environmentally friendly systems and ultrasonic cleaners from ½ to 183 gallons.

We have an established testing laboratory and engineering department that can help with design or application needs. We encourage our customers to send sample parts for testing to ensure that product they are ordering is the most efficient, cost effective and safe process available for their specific needs.
