DIRECTIONS FOR USE & APPLICATION Step One - Strip Firearm Unload and field strip firearm according to the manufacturer's instructions. Wipe parts with a rag or quality paper towel. To degrease the gun, rubbing alcohol works. Shake product bottle and remove (and retain) red stopper. Apply FIREClean™ oil to fouled parts. It extracts fouling like you won’t believe. Allow to soak in overnight if possible. Wipe fouling off. Fouling may continue to "weep" out of the metal for a period of days, depending on the porosity of the metal and amount of fouling. Wipe the fouling as it comes out of the metal. You may see machining marks in upper receivers, bolts, etc that have been previously camouflaged by carbon fouling.
