In this tutorial, we learn how to clean glocks. First, field strip your gun down, ten take your brush and place a clean cloth tightly over it. After this, add gun cleaner to the cloth and then push this through the barrel, it should be tight. Next, spray gun cleaner onto the brass brush, then run through the bore and go through the entire thing, don't switch direction while in the barrel. Next, install the patch tip onto your cleaning rod and thread the patch through. Leave it dry and make some passes through the barrel. When you are finished, piece the gun back together, then make sure the safety is on and enjoy your gun.
