IOSSO bore paste
NEW BIO-Based Formula. Highly effective concentrated paste formula that lasts longer and takes less time to clean with than ordinary liquid or aerosol type cleaners. Because it is a paste it cannot spill or run into wood stocks, grips or mechanisms causing chemical damage. Iosso Bore Cleaner removes copper, lead, carbon burn, powder fouling, plastic wad residue, and surface rust. It is non-corrosive, non-flammable and has no offensive odors or mists. Use with the Eliminator Brushes and Eliminator Triple Action Oil Solution for complete cleaning.
We find this product very good at removing powder fouling in the throat area.
