Hoppes No 9 Blast & Shine Cleaner Degreaser 11oz (SKU: HPCD1) is a heavy-duty, high-performance cleaning aerosol engineered to forcibly clear and degrease metal firearm mechanisms without requiring complete disassembly. Formulated with a high-pressure, quick-evaporating solvent propellant, this cleaner physically blasts away carbon, caked-on grease, dirt, and heavy oils from assembled receivers and fire control groups. The eco-conscious chemistry is designed to deliver modern degreasing performance without the severe toxicity hazards associated with older chlorinated solvents, containing zero chlorofluorocarbons (CFCs) and no known carcinogens. It evaporates rapidly within seconds, leaving behind zero oily residues or films on bare metal components.

Key Features

• Disassembly-Free Action: High-pressure spray format physically clears carbon, dirt, and caked-on grease from assembled firearm receivers.
• Rapid Evaporation: Dries completely in seconds, leaving no oily residues, films, or moisture behind.
• Deep Solvent Penetration: Cuts through hardened packing grease, cosmoline, and old carbon build-ups on contact.
• Targeted Application: Includes a flexible straw extension to direct the high-pressure stream into tight tolerances and deep recesses.
• Eco-Conscious Chemistry: Formulated with zero chlorofluorocarbons (CFCs) and no known carcinogens.

Who is the Hoppes No 9 Blast & Shine Cleaner Degreaser 11oz for?

• Competitive shooters — requires a powerful 11 oz high-pressure aerosol solvent to rapidly strip carbon and debris from high-round-count bolt carrier groups and triggers, restoring metal surfaces to a completely dry state without full disassembly.
• Military surplus firearm collectors — relies on this 11 oz aerosol degreaser's deep-penetrating solvent action to cut through heavy, hardened cosmoline and packing grease on historical metal actions and barrels.
• Hunters — benefits from an eco-conscious formulation containing zero chlorofluorocarbons (CFCs) to perform quick, high-pressure field maintenance on gas pistons and choke tubes, blowing away carbon buildup on metal parts.

Less suitable for: Cleaning applications on sensitive synthetic stocks, polymer frames, or delicate optics, where a specialized plastic-safe cleaner is required to prevent material degradation. It is also not suitable for use near open heat sources or in environments exceeding 50°C, and because it strips all lubrication, it requires the immediate post-application use of a dedicated gun oil or rust preventative.
