Abstract
Mixtures comprised of the compounds trans-1,2-dichloroethylene and/or cis-1,2-dichloroethylene and perchloroethylene are disclosed; as is a method for cleaning a solid substrate which comprises treating the substrate with said mixtures. A method for precision cleaning is disclosed, comprising the steps of showering the contaminated surfaces with said mixtures and then rinsing said surfaces with said mixtures that have been cleaned by distillation in-system. A method for dissolving and reconstituting polymers, waxes and oils by use of said mixtures or by use of mixtures consisting essentially of trans-1,2-dichloroethylene or cis-1,2-dichloroethylene is also disclosed; as is a method for delivering polymers, waxes, oils paints, pesticides, insecticides and fungicides to a surface by use of said mixtures or by use of mixtures consisting essentially of trans-1,2-dichloroethylene or cis-1,2-dichloroethylene.
