After all, the custom-made materials of Souvenir Medal are all alloy or precious metal. As time goes by, protection is not appropriate and will naturally lead to its surface rust.

But the rusty commemorative medallion can also be processed by chemical method, there are commemorative medallion customized manufacturer for you to answer:

For the less oxidized MEDALS, we can use a slow reaction, such as 5% dilute sulfuric acid, to gently wipe the surface, after treatment, and then put into a dry box to preserve.

For the MEDALS with more oxidation, they can be soaked in solution for 3 days, and then stored in a dry box.

We can also make the commemorative MEDALS produce natural oxidation layer and increase the gloss through later treatment. The methods are as follows:

Soak the clean and greaseless medallion in 10% 2-sulfite for 15 seconds, remove it and dry it with a dry towel before putting it in storage. This way, the medallion will be very shiny and will not be corroded any more.
