including cleaning and degreasing purposes, because they possess
the superior characteristics listed below.
have high mutual solubility with other organic solvents and also

using plastics and rubber as they tend to dissolve or swell them.
stabilizers are added to methylene chloride, trichloroethylene,
and tetrachloroethylene used for cleaning purposes to suppress their
decomposition during usage, neutralize the acids produced by their
decomposition, and prevent corrosion of metals.
conditions of temperature and pressure, methyl chloride is a colorless
