Sterling Perak Peringatan Pingat - Bagaimana Harus It Be Dikekalkan?

The silver commemorative coin is soft and will leave traces once it is hit by hard objects. Therefore, when maintaining silver commemorative coin, first of all, avoid direct collision and friction with hard objects. Do not put several coins in one pocket at the same time so that they can rub against each other. Therefore, each each silver commemorative coin should be sealed with a acrylic sleeve.

Firstly, avoid contact with acidic and alkaline substances, which can oxidize the silver surface. Silver commemorative coin should be stored in a ventilated and dry place.
The method of cleaning silver commemorative coin first depends on the oxidation degree and quality of silver coins. If silver coins with high silver content are only slightly oxidized, it is best to use ammonia solution, sodium carbonate solution, and toothpaste to make a paste for cleaning, or mix edible white vinegar with a small amount of water, soak the silver coins in their solution for a few minutes, or gently wipe the coin surface with a cotton ball dipped in the solution. After the oxide layer on the coin surface dissolves, rinse it with water or clean it with silver washing water.
Anyway, stay away from dampness and avoid direct contact between hands and commemorative badges!
