Immunol® AC-11 is a cleaner/brightener for usage in vibratory finishing or tumbling operations. A mildly acidic compound, it brightens steel, copper or brass parts. It provides detergency and wetting to suspend and carry off oils and smut from the surface of the metal parts being cleaned. It will not rust steel media. It is inhibited against attack on aluminum, so it will not etch the surface. This product is compatible with plastic, steel or ceramic media.
