IOSSO Bore Cleaner is a concentrated paste formula. IOSSO Bore Cleaner reduces cleaning time and results in a cleaner bore than what you would get using ordinary solvents. It removes copper, lead, powder, fouling, plastic wad residue, surface rust, and carbon burn which occurs at the neck portion of the chamber.
Because of the paste formula, IOSSO Bore Cleaner cannot spill or run into wood stocks, grips, or mechanisms therefore eliminating the potential for chemical damage. This Green Bio-Based formula is made from plant extracts.
