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.
