Rimfire barrels are notorious lead fouling traps, and keeping them clean without harsh chemicals or lengthy scrubbing sessions is exactly what the Bore Tech Rimfire Blend 16oz is designed for. This purpose-built bore cleaner is formulated specifically for the demands of .22 LR and other rimfire calibres, targeting lead deposits, bullet wax, powder fouling, carbon, and corrosive residue in a single application. Bore Tech's exclusive blend of surfactants, penetrants, and releasing agents penetrates and lifts fouling efficiently, meaning less time on the bench with a brush and patch and more time shooting. At 16oz (473ml), this bottle gives you serious cleaning capacity, whether you're running a high-volume pest control rifle that sees heavy lead-fouled use or a precision rimfire that demands consistent barrel condition for repeatable accuracy.

Bore Tech Rimfire Blend 16oz Key Features

• Rimfire-Specific Formulation: Engineered specifically for rimfire barrels, addressing the particular fouling profile of rimfire ammunition including lead, bullet wax, powder residue, carbon, and corrosive salts that accumulate quickly in high-volume rimfire use.
• Exclusive Surfactant and Penetrant Blend: Uses a proprietary combination of surfactants, penetrants, and releasing agents to break down and lift fouling from the bore with minimal mechanical effort, reducing the number of brush strokes and patches required per session.
• Safe for Overnight Soaking: Can be left to soak in the barrel overnight without risk of damage, which is particularly useful for heavily fouled barrels or bore-snakes that benefit from extended dwell time.
• 100% Barrel Safe: Safe for use on all rifled and smooth bore surfaces and will not harm the bore. Also confirmed safe for use on polymer and sealed stocks, so there is no need to mask components during cleaning.
• Corrosion-Inhibiting Residue: Leaves a thin protective film on metal surfaces after application, providing short-term rust and corrosion inhibition between cleaning sessions.
• Ammonia-Free and Odour-Free: Contains no ammonia, making it pleasant to use in enclosed spaces such as workshops, cleaning rooms, or gun safes. The absence of ammonia also means no risk of stress corrosion on copper or brass components.
• Non-Hazardous, Non-Flammable, and 100% Biodegradable: A genuinely user-friendly formulation that does not require special ventilation, protective equipment beyond standard precautions, or hazardous waste disposal.
• External Barrel Use: Can be applied to the outside surface of a barrel to remove external carbon and lead fouling, not just for bore cleaning, making it a versatile part of a rifle maintenance routine.
• Bottle and Cap Design: Supplied in a treated HDPE plastic bottle with a twist open/close dispensing cap fitted with a foam gasket seal, giving controlled dispensing and a secure closure to prevent leaks during storage and transport.
• Wood Stock Caution: Not suitable for direct contact with oiled wooden stocks, as the formula may strip the oil finish. Re-oiling will be required if contact occurs, so care should be taken during application.

Bore Tech Rimfire Blend is a no-nonsense, chemically sound cleaning solution that makes rimfire barrel maintenance faster, safer, and far less unpleasant than older solvent-based products. The 16oz (473ml) bottle ensures you will not be running short mid-session, and the biodegradable, non-hazardous formula means it is as practical for the environment as it is for your barrel.
