ABSTRACT:
A solvent mixture for use in vapor cleaning degreasing systems. Dibromomethane is used as the principal component instead of such high ozone depleting chlorofluorocarbons as Freon and 1,1,1 Trichloroethane. Dibromomethane is mixed with other solvents including a number of low boiling solvents which prevent the mixture from becoming acidic on the release of bromine into the atmosphere.
