How should I clean my gun?
There are many procedures you can follow, but we have described two common ones below.
Soak a cleaning cloth with solvent or oil and pull it through the barrel. Pour solvent onto a suitable bronze brush. There are many different kinds that you can try out – different guns have to be cared for in different ways. Do not immerse the brush in the bottle, as the brush's ability to clean the barrel would quickly be impaired. Pull the brush through the barrel three to ten times, but be careful when pulling it back out of the muzzle. Once it is out of the muzzle, you can unscrew the brush to prevent it from scouring the muzzle. Leave the solvent on for at least 5 minutes and then wipe it off. Insert a cloth until just in front of the muzzle and check for tombac residue. Repeat the process, if necessary. If you use a cleaning rod guide, you can reduce contamination on the magazine and chamber to a minimum.
Another cleaning method involves using a paste, not carborundum but special, softer agents. After removing most of the residue with a cloth soaked in oil, wind a cloth round a smaller brush making sure it touches the sides inside the barrel. Apply the paste right round the brush and clean the barrel with the brush. As most deposits occur at the start of the barrel, rub this part with the brush about three to five times longer than near the muzzle. After a short time, you may have to apply more paste. Cleaning with paste is a somewhat messy affair and when you have finished you have to check that there is no paste residue left in the barrel. We have seen barrels that have been destroyed because their owners did not carefully remove all traces of paste after cleaning.
If you shoot so often with a barrel that hardened residue is difficult to remove, it is best to use paste. You should therefore clean with paste every now and again. Once you have gained some experience, you can tell what kind of cleaning is required. If you also have a bore-scope (endoscope), it is a great help – it means you can easily inspect the state of the interior bore.
