Solvent-Based Parts Washers come in a variety of types from one-gallon dip buckets and recirculating systems to large pressure- washing units. Parts Washers can contain these types of : • Citrus-based Solvents • Mineral Spirits • Xylene • Naptha and/or Petroleum Distillates • Benzene and/or • Trichloroethylene Aqueous Parts Washers can contain “nonflammable” & “nontoxic” chemicals when purchased; but as they are used, these chemicals are mixed with potentially hazardous constituents from the metal objects being cleaned.
