Metal trophies and medals often represent the honors obtained, and have high commemorative price and collection significance. However, metal trophies and medals have a lot of care. In order to summarize and sort out the following five common and practical methods:



1. The dust on the metal cup and medal should be wiped off with a clean and soft cloth, and those details that need special care should be brushed off with a soft brush or vacuumed or blown away;



2. To prevent metal trophies and medals from mechanical damage, they should not collide with each other and should not be stacked;



3. The space for placing metal trophies and medals must be kept dry and free of dust and air pollutants. The temperature is 18 ℃ - 24 ℃, and the relative humidity is 40% - 50%;



4. Prevent contact with harmful chemical substances produced by metal trophies, such as acids, grease, chlorides, etc.



5. After the metal cup and medal are placed for a long time, some dullness will appear more or less according to the environment. At this time, you can use cotton and silk fine cloth to gently wipe back and forth to achieve the polishing effect, so that the protective wax layer on the surface will glow again.
