Metal Guard 820 is a water-soluble alkaline liquid concentrate specifically formulated to
provide temporary rust protection of steel indoors. It leaves a dry, invisible, non-oily film that
will not hinder subsequent operations. Metal Guard 820 solutions can be used as a final dip
in tumbling or soak operations to prevent possible oxidation of steel parts. Being a water
solution, it does not present a fire hazard, nor does it present a toxicity problem.
