Step 1: Stuff You Need

The things you need :
- a few copper coins
- a cup
- a tweezer
- a measuring cup
- salt
- vinegar

Step 2: Measure

You'll need 5 cc/ml salt and 15 cc/ml vinegar

Step 3: Mixing

First put everything together in the cup and then mix everything very good

Step 4: Coins and Waiting

Throw the coins in the cup and wait for 2 hours

Step 5: Finishing

Now the last step you need to take the coins out of the cup with the tweezer and now we have shiny shiny copper

Step 6: Why?

When salt and vinegar are mixed together, you get hydrochloric acid. This acid is often used to metal objects to clean. The coin is made of copper. After a bath in the copper salt-vinegar solution is clean again.

    just a quick note here..... if you have old collectable coins you don't want to clean them. If you do the coins loose their collective value. Most serious collectors want to see the natural patina on the coins.

    That being said, it is fun playing around with highly corrosive compounds!

    Or you can use some tomato ketchup/mayo.

    Just put a drop of ketchup or mayo on the coin and wipe with a cloth. Simple and quick. No instruments required!!

    Job done!!

    As soon as you clean a coin it looses it's value completely.

    Do not clean old coins or silver and gold this way. But yes this vinegar salt works fine for brass and copper.

    You explanation at the end does not explain why the coins get clean very well.

    Maybe you should reword it.
