Walther Valve Cleaning Cartridges 5-Pack

The cleaning cartridge is filled with a special lubricating oil, which greases the valves and the weapon itself. It is recommended to use after 10 CO2 cartridges. A maintenance cartridge is used instead of the CO2 cartridge and completely shot empty (Note: Remove the magazine beforehand). For this purpose, the gun should be kept upside down, so that the special oil can be better distributed. After cleaning one should directly de-oil the barrel with Walther quick cleaning pellets! It is recommended to clean outdoors as an oil mist escapes.
