Some positions of the buckle lock are hidden, so it is not easy to maintain in the process of use. So how to maintain it? Since most of the metal rust is attached to the surface of the concealed buckle lock, it is a loose, porous solid material, which is not firmly combined with the metal. Under the action of external force, it can be modified to peel off the metal body, which is also the most important principle of physical rust removal. External force can be applied by shot blasting, sand blasting, polishing, polishing, etc. The corrosion products of metals are mostly composed of metal oxides and hydroxides, so they are easy to react with acids. The precipitation of hydrogen can reduce the iron oxide and magnetic iron oxide in the rust layer of the concealed buckle to ferrous oxide which is easy to react with acid, which is conducive to the dissolution of oxides, and can also promote the exfoliation of insoluble oxide cortex and accelerate the removal of oxides. However, hydrogen may also be absorbed by the base metal and cause hydrogen embrittlement. Ponadto bardzo ważne są codzienne czyszczenie i konserwacja.
