How often do you clean your Condor/Talon barrels?

The easiest way to clean the barrel is to take a lenght of line from a weed eater (.080″ diameter X about 3′ long), sharpen one end, then for the other end…heat it with a lighter and press the softened end (not too hot or it will melt it completely) onto a piece of metal to make a little ‘nail head’ shape small enough to fit down the barrel. Take a .22 cleaning patch and pierce a corner with the sharp end of the line and slide the patch down to the formed nail head end. Thread the sharpened tip trough the barrel out the muzzle, then pull it through with a little denatured alcohol soaked into the patch, or some 90% anhydrous rubbing alcohol if you can find it at the local drug store. This will clean it well, and will not damage the metal.
This is form a guy I met over the holiday. He has multiple weapons and trains athletes for the Olympics for airguns. He said that is the best way to clean airguns. They don’t need lube.
