Shooters Choice Foaming Bore Cleaner Features Shooters Choice Foaming Bore Cleaner works by expanding once sprayed into the breech so the foam reaches the full length of the bore and surrounds fouling rather than just the surface a patch happens to touch. The firearm should be unloaded and placed in a gun vise or laid on a horizontal surface with the breech slightly higher than the muzzle which keeps the expanding foam from seeping into the action as it works. Letting the foam sit gives it time to break down carbon and copper fouling before any mechanical cleaning is needed. This approach cuts down on the number of patches and brush strokes required for a thorough clean. Once the foam has broken down it is removed with whatever cleaning kit the owner already uses so no specialized tools are required to finish the job. The manufacturer recommends following up with a quality lubricant and protectant after cleaning to guard the bore against corrosion between range trips. Packaged in a compact 3-ounce aerosol can the product is easy to keep in a range bag or cleaning kit without taking up much space. Made in the USA Shooters Choice Foaming Bore Cleaner gives shooters a straightforward way to keep a bore clean and ready for the next outing.
