Gets gun bores squeaky clean and shining but is harmless to all metal surfaces, including titanium, aluminum and stainless steel. Actually breaks down carbon so copper and lead fouling float free; completely odorless, non-flammable, non-toxic, biodegradable and environmentally safe to use. Penetrates hydrocarbon-based greases, oils (will damage oil-based stock finishes) and gun powder residues; strips the metal completely clean but leaves a thin, rust inhibiting film with no oily feel. Heat and agitation will accelerate the cleaning action. Can be used as a tank solvent. Not a lubricant. Mfg: M-Pro 7 SPECS: 4 fl. oz. (118 ml), 8 fl. oz. (237 ml) pump spray bottle, 32 fl. oz.
