Speeds up the time-consuming, labor-intensive job of cleaning automatic gas piston parts and choke tubes. All you do is soak, rinse, and wipe clean; it only takes 15 minutes or less! Plus, EZ-SOAK makes short work of carbon, copper, powder, and plastic wad fouling. Use it on barrels, bores, chambers, cylinder faces, bolt faces, and other hard-to-clean areas. For parts that are too big to fit in the jar to soak, just apply EZ-SOAK to the part with a nylon brush or rag. This is a non-caustic, non-petroleum product and requires thorough application of a rust-preventing oil after use.
