open discussion on cleaning clad coins.

	Because some of them coins change color when you clean them I can not count the times I had to explain to the store keeper that they were real and not fake.

Seems to me if someone was going through all the trouble to make fake ones they would look a lot better than our dirty old park coins.

A bad day at gold prospecting or metal detecting is better than a good day at work.

	Don't they think that it is easier to make paper money than minted Money, Turkey's  aren't they??

Yes they are.
Back to the coin cleaning.
You can try real lemon juice instead of vinegar.
It’s a stronger acid and works faster. Make sure you don’t mix copper with nickel

I think I will try that to see how it works. I looked it up and lemon juice is 5% to 6% acidic and vinegar is approximately 5%.  Also, it said lemons are native to Asia and that they are an evergreen.  Thousands of orange and lemon groves here in the valley, and never knew that. Makes me wonder what else they never told me.

James, I have only cleaned a little over two hundred, but I am seeing the same results. A word of advice on clad pennies though. It will eat through copper faster than it does nickel. I lost one penny that I accidently left in the solution for two hours. The back side was gone and the front side was eaten away on the edges. The back was blackened and the design was gone. I suppose if you clean a lot of clad coins you probably should not be throwing the solution down the drain. The nickel will enter into the solution and turning it blue. This is nickel chloride and sodium acetate now. Dispose of it properly. Don't store it next to the mouth wash.

Tumbler, Dish Soap, Aquarium Gravel works for me.  I do not mix coins.  Pennies one run and wanta be silver another.

Thanks for that input Homie and Arfie. I will remember those options if I give up on this vinegar/salt solution. I think I have discovered what causes the cloudy film on the nickel plated coins. It looks like it might be citric acid crystallization. And the good news is that anhydrous ethanol will dissolve it. Don't worry that stuff is safe cause it's in beer and wine and all booze.  Rubbing or wood alcohol are not the same type of alcohol. That may sound sacrilegious to some of you if I use it to clean my coins, but I am a non-drinker and I won't need much to clean the coins. 1 can should last awhile. If it was the last can on earth I would save it for you all.
