Remington Solvent 40-X (Remington part no. 18397) is a bore cleaner built to cut through powder and copper fouling across rifles, shotguns, and handguns, giving shooters a single solvent that covers most of the firearms in a typical collection. Applied to a patch or brush, it breaks fouling down faster than a plain dry patch alone, cutting the number of passes needed to reach a genuinely clean bore. The 4 oz size is a practical, bench-ready quantity that lasts through many cleaning sessions without taking up excess storage space. A dedicated bore solvent like this remains one of the simplest ways to protect accuracy and prevent long-term corrosion.
