Keeping firearms clean and properly maintained will not only add to their overall lifespan and performance, but can also keep the weapons more accurate and able to hit targets at maximum distances. Kano Kroil is a penetrating oil that has gained a large following for its quality performance when it comes to keeping a firearm in optimum condition. Kroil is adept at getting into the micro-crevices of some of the tougher firing residues found inside of the barrels of firearms and loosens them up to allow for quick and easy removal during the cleaning process.
Unload the weapon and clear the chamber.
Attach the bronze bristle brush to the cleaning rod and apply generous amounts of Kroil. Pass the bristle brush through the gun barrel in a back and forth motion for approximately 20 strokes.
Remove the bronze bristle brush and wipe the cleaning rod clean with a clean rag.
Install the patch jag on the cleaning rod and attach a cotton patch to the jag.
Soak the patch in Kroil and pass the jag from the chamber end through the barrel and out the muzzle. Do not pull the jag back through the barrel; allow the patch to fall off once it has breached the muzzle opening.
Wipe the cleaning rod clean and attach a new cotton patch. Repeat the previous step until the powder fouling has been removed, wiping down the cleaning rod between each cotton patch. Three passes are generally sufficient.
Wipe down the cleaning rod and attach a new cotton patch to the jag.
Apply copious amounts of copper solvent to the patch and pass the jag through the barrel, taking care to never pass the jag back through the barrel once the cotton patch has breached the muzzle. Follow up the first cotton patch with a second cotton patch, prepared in the same fashion, immediately after the first pass.
Wait five minutes and repeat this procedure until the cotton patch no longer has a blue/green color (copper residue) when it exits the muzzle.
Wipe down the cleaning rod and attach a dry cotton patch.
Pass two or more dry cotton patches through the barrel, using the same techniques as before, to remove any traces of the copper solvent.
Wipe down the cleaning rod and attach a new cotton patch with a rust preventative compound applied and pass it through the barrel according to the manufacturer's instructions.
The last step is only necessary if the weapon will be in storage for a long period of time without being fired.
Never leave the copper solvent in the barrel for more than four minutes to avoid pitting and other serious damage. The drying step of the cleaning process will help avoid leaving solvents in the barrel and should be done with attention to detail.
