You would see that using baking soda to clean coins is both harmless and effective.



If using pure baking soda does not produce good results, you can try by mixing a little water. Clean the coins and repeat the procedure until all the stain is gone. Note that baking soda will serve as a perfect cleanser for cleaning silver coins than for copper coins. If normal rinsing doesn’t help, you can try dipping the coin in baking soda solution for a few minutes and leave it for some time. Then take one coin at a time and brush the surface gently with a soft toothbrush.



Usually, to clean silver pieces, you can use aluminium foil and very hot water mixed with baking soda. Water should be very hot as this is vital for this process. Using warm water will not serve the purpose. Water should be heated to higher temperatures until boiling point of water is reached or any point close to it. Mix baking soda with hot water and take a sheet of aluminum. Make sure that the size of the container you use is is adequate to immerse the coins. The coins should touch the base of the sheet.



You can remove silver tarnish with this easy process. For this, all you need is baking soda, aluminium foil, and salt. There is no need for a polishing cloth or silver polish. This will clean the tarnish right off.



Do you want to try more techniques? Take a black-toned coin. Get a dish and cover its bottom with aluminium foil. Pour baking soda on the foil and place the coin inside it. Now add boiling water and wait. In a few minutes, the black layer over the coin will be removed and the coin would look as if it’s almost new. The effect of baking soda removes away the black layer on the coin.

Note: Silver coins must be in physical contact with the aluminium foil.

Do not ignore cleaning high grade coins. Be aware of all the cleaning techniques that are available to you. If you use other chemicals to clean the coins, they may get damaged. Also, costlier coins should be least cleaned to avoid losing their character. If this happens, coin collectors may refuse to buy them.
