How to quickly clean copper parts, wires, coins
We take two glass containers. Pour plain water into one and add a teaspoon of baking soda. Stir well. This solution will serve to neutralize the acid.
Place a teaspoon of table salt in another container.
Add vinegar and mix well.
Place the copper piece in a vessel with a solution of salt and vinegar.
We wait 5-15 minutes. After this we take out the copper part.
You can immediately see that the copper has brightened and cleaned up.
Next, to neutralize the acid, place the conductor in the soda solution for a couple of seconds.
Take it out and wipe it with a dry cloth.
If the copper part is not sufficiently cleaned, you can repeat the operation and immerse it in a vessel with vinegar and salt for a longer time.
