Precautions:
(1) The packaging should form a closed space.
(2) The metal surface must be dry and free of any residue that may cause rust, such as sweat stains, or any substances remaining on the surface after cleaning processes, such as acids or strong alkalis, which can affect the actual anti rust effect of the packaging.
(3) Do not directly contact wood or acidic substances on the metal surface.
(4) The rust prevention time is related to climate conditions and the sealing effect of packaging.
