The barrel should be cleaned before storage, or at least after 500 shots. To clean the barrel, use a cleaning rod (for rifling preservation, avoid brass brushes) or cleaning pellets to be fired as a real pellet. You can apply a drop of gun oil into the breech. After every 1,000 shots, apply a drop of gun lubricant into the compression chamber. Blued parts, such as the barrel and compression cylinder, should be protected from rusting. Maintain protection by wiping these parts with a lightly oiled pad. All visible mechanical parts, breech, trigger and safety may be lightly oiled as need to maintain proper function.
