Exclamation RE: AMAZING method for cleaning ancient SILVER coins

Hi,

Please NOTE: This method can be VERY DANGEROUS if done carelessly or improperly. EXTREME CAUTION is highly recommended.

Here is an AMAZING method for cleaning SILVER coins (only works with solid silver coins, as it will be destructive on bronze coins):

1.) Boil Water

2.) Wrap SILVER coins in aluminum foil. You can wrap several coins by first wrapping one, then folding, and adding another coin, then adding another, etc., each time separating the coins from one another by wrapping each one entirely in foil.

3.) Pour boiled water in glass bowl that you won't want to use again for eating.

4.) Add the foiled coins to the water so they are covered in water

5.) Add SULPHURIC ACID (beware of toxic fumes from the reaction).

6.) After reaction has ceased in a few minutes and the mixture is relatively inert (i.e. no more smoke will be seen coming from the mixture), you can remove the coins.

7.) Dip each one quickly in baking soda both sides.

8.) Rinse with water and repeat, scrubbing with toothbrush and/or finger if necessary.

The above method takes silver coins that are tarnished and nearly black in color and turns them into brilliant silver in 10 minutes, no scrubbing. However, if you want to make certain the whole coin will brilliantly shine, it will be necessary to scrub with the toothbruth and baking soda in order to clean those tiny crevices and grooves on the coin.

This only works with SILVER coins exactly as above.

Enjoy!

If you have an ancient coin that is tarnished, and then clean it, you have killed the coin.

Ancients are better with tarnishing and color...It is prefered over the shiny silver ones.

I have to caution, again, to begin with only distilled water and gentle brushing. Then, eventually, graduate to picking. This really seems like overkill, especially considering that the few uncleaned silvers I've seen have come out quite nice without this method.

sulphuric acid reacts bad with water so I'd suggest having alot of baking soda around to nutralize it


I dont recomend this but.... I'd rather use lime away to clean it and ciggerette ashes to shine it.
