DuraClean-612 is a non foaming and highly effective soak cleaner and excellent electrocleaner (direct or reverse) for steel, brass, copper, zinc, nickel, cast iron and stainless steel. Its medium alkalinity makes it ideal for these common metals in a job shop type operation. DuraClean-612 effectively removes all common types of fabricating oil and can also be used for electrolytic stripping of chrome deposits in a separate tank.
