The method of cleaning ancient coins with hydrogen peroxide
Those who use hydrogen peroxide are the treasures of time. It carries the history, literature and art of the past, and is of extraordinary value. However, after years of erosion, it is often dusty and damaged. Today there is a method of cleaning ancient coins with hydrogen peroxide, which is detailed below.
The first thing to check is the quality of the coin. Coins of different materials react differently to hydrogen peroxide. For example, copper coins, although hydrogen peroxide can remove part of the rust, you need to be careful when using it, because it may react with copper, which will damage the color and texture of the coin. Silver coins are relatively suitable, and hydrogen peroxide can effectively decontaminate and scale, restoring its shine.
The backup device is also necessary. A container that needs to be cleaned, preferably glass or plastic, to prevent reaction with hydrogen peroxide. Prepare another soft brush, such as a wool brush, for gently wiping the surface of the coin.
Take an appropriate amount of hydrogen peroxide in the container. The concentration should be 3% - 6%. If it is too thick, it will easily hurt the coin. Lightly place the ancient coin in the hydrogen peroxide and soak it. When soaking, it depends on the degree of stain of the coin. If it is light, it may take one or two days if it is heavy. During this period, you can observe its changes and adjust it in a timely manner.
After soaking, take the coin and buffer it with water to remove the residual hydrogen peroxide. Then use a soft brush to gently brush the surface of the coin to remove the loose scale. When brushing, use force evenly and lightly to prevent the lines of the coin
After brushing, wash it with water and wipe it lightly with a soft cloth to absorb moisture. Put the coin in a ventilated and dry place to dry, do not expose it to sunlight, and avoid discoloration.
Although this method can clean ancient coins, it is not applicable to all. Rare coins, or those of unknown materials, should be consulted with Fang's family first to avoid damage.
