Abstract
A process for the stabilization of perchloroethylene which contains known epoxides as stabilizing agents which is characterized by addition of an effective amount of 1,2-epoxycyclooctane and/or 1,2-5,6-diepoxycyclooctane. As a result of this addition the cleaning effect of the perchloroethylene on metals is maintained for longer periods, corrosion phenomena are avoided and formation of greasy deposits on the goods to be cleaned will no longer take place.
