Necessary

  • - lemon;
  • - flour, salt and vinegar;
  • - vinegar and hot water;
  • - tooth powder or paste;
  • - liquid for cleaning jewelry;
  • - a cloth;
  • - Toothbrush;
  • - old newspaper.

Instructions

Step 1

Take a half of a lemon, stick a coin into its pulp and let it "soak" a little. After about 15 minutes, remove it and brush it clean. Rinse in cold water and dry with a soft cloth.

Step 2

Combine some flour, coarse salt and a drop of vinegar. Rub the coin well with the resulting mixture, wait a little and rinse in clean running water. Be sure to wipe the copper dry, otherwise dark spots will form almost immediately.

Step 3

Dissolve the vinegar in boiling water. The approximate concentration of acetic acid should not exceed 20-25%. Add 2-3 tablespoons of table or sea salt and dip the coin into the solution. When the water and vinegar has cooled down, carefully remove the coin and brush with an old toothbrush. Rinse in clean water and dry with a cloth. Be careful when working with a concentrated vinegar solution, you can get poisoned by fumes.

Step 4

If you have toothpaste, use it, if not, regular whitening toothpaste will do. Moisten a coin and rub it with paste or powder, brush it with vigorous movements. Rinse and look at the result, if it does not suit you, repeat all over again.

Step 5

Jewelry cleaner can also restore copper to its original appearance. Buy the product from a jewelry store or workshop, dip the coin for a few minutes, and wipe thoroughly with a clean cloth. If you are worried about the integrity of the coin and are afraid to clean it yourself, contact a jewelry workshop. You will be professionally cleaned and polished metal, and a special colorless coating will be applied to protect the copper from blackening.
