To collect military aluminum kettles without oxidation, first check the surface coating to make sure there are no damaged areas. Secondly, place them in a cool and dry environment.
Military aluminum kettles are aluminum products with a layer of military green paint on the surface. As long as the paint layer is not damaged, the surface will not be oxidized. Do not put water inside the kettle, place it in a cool and dry place, cover it with a lid to prevent water vapor from entering. In the absence of water, the metal aluminum will not be oxidized, so it can be stored for a long time.
