Iosso Products is an American manufacturer of specialty cleaning and maintenance compounds based in the United States. The company has decades of experience in metal cleaning and polishing for industrial, marine, and recreational markets, and that background eventually led to a dedicated line of firearms maintenance products that rely on their abrasive and bio-based chemistry.
Iosso Bore Cleaners and Paste
The Iosso bore paste is their signature gun-care product, a white concentrated paste that uses fine abrasives to remove copper, lead, carbon, and powder fouling mechanically. You apply it with a brush or patch, work it through the bore, then follow with clean patches until they come out clear. Because it is a paste rather than a thin liquid, it stays where you put it, which helps prevent runoff into stocks or internal mechanisms when you are cleaning indoors.
Many shooters pair the bore paste with less aggressive liquid cleaners or oils for regular maintenance, using the paste when they need a deeper clean. The paste is particularly useful for breaking up stubborn copper and carbon buildup in precision barrels, so you can restore accuracy without relying on harsh ammonia-based cleaners.
Brushes and Kits
Iosso manufactures their own bore brushes that are designed to work with abrasive compounds. The Iosso nylon bore brush is stiff enough to drive paste into the rifling but soft enough that it will not scratch steel, making it a good match for repeated mechanical cleaning. They offer bronze brushes as well, so you can choose between more traditional brush materials and synthetic fibers.
The Iosso AR-15–focused cleaning kits bundle caliber-specific brushes and their cleaning compounds into a practical package for owners of that platform. Individual Iosso brushes are available in standard rifle and pistol calibers, with brass cores and securely attached bristles so they hold up to repeated passes through the bore.
Case Cleaning Products
The Iosso brass case cleaner serves reloaders who want a quick way to clean brass using a liquid solution rather than relying only on dry tumbling. The brass cleaner is a liquid formula that removes fouling, tarnish, and residue from case surfaces, including areas like the primer pocket where tumbling media does not always reach effectively.
Iosso case polish is designed to be used with tumbling media to restore shine and a smooth surface to brass that has already been cleaned of heavy residue. The Iosso case cleaner kits typically combine the liquid cleaner with basic accessories such as a container and immersion bag so you can process batches of brass efficiently before polishing.
Why We Stock Iosso
We carry Iosso gun cleaning products at No Boring Guns because many European shooters are looking for effective alternatives to strong-ammonia or solvent-heavy formulas. Their bore cleaners and case-care products work well for precision rifle shooters who want thorough copper and carbon removal without harsh fumes, and for reloaders who inspect each case closely. Pricing for Iosso cleaners and pastes generally sits in line with other specialized gun-care products, and a single tube or bottle typically lasts through many cleaning sessions, which makes them a practical long-term choice.
