Because salt vinegar water is an acidic solution, it can dissolve dirt, so the stains on our coins can be dissolved by soaking in salt vinegar water, so the stains are easy to clean.
Wash washing powder. If it really doesn't work, soak it in white vinegar for a long time, which is easier to clean. But not for ten days and a half. After all, the plum blossom fifty cents are metal, and long-term immersion will make the plum blossom fifty cents corrode. If there are many plum blossom coins, I suggest soaking them in salt water before brushing them with a brush. This effect is more obvious.
Cleaning method of coins:
Preparation materials: salt, vinegar, small pot.
1. Pour the salt and vinegar into a small basin according to the ratio of 1 ratio 10, and stir until the salt is completely dissolved.
2. Pour the coins into the mixed liquid, and the amount of water should not completely exceed the coins.
3. Soak the coin for five minutes, which shows that the dirt on the surface of the coin is much less.
4. Take out the coin and scrub it with a clean soft cloth. Let it dry for 5 minutes, and then it will become very bright.
