How do I get these white marks off of my souvenir pennies after leaving them in vinegar for a year?

Question

I was told that vinegar would clean pennies, so I left my hard-earned souvenir pennies in vinegar. I ended up with white marks on my pennies. Help!

Answer 1

That is permanent I think. Try some pure acetone from the hardware store a quick dip and then rinse withclean water and pat dry.

Answer 2

Whoever said vinegar was wrong. Vinegar contains about 5% acid if you check the label. The white marks are corrosion build up, the same effect that happens to your battery terminals on your car after a while.Car batteries contain acid.I would suggest boiling a pot of hot water, then put all the pennies in it for a while.The boiling water should dissolve most or all the corrosion build up. As far as cleaning them, I would try using jewelry cleaner. I hope this helps some.

Answer 3

In the future you should never clean any coins with any cleaner natural or chemical.

It reduces the value of them. I had 25 Silver Dollars that were cleaned by someone. They basically worthless now.

They could of been worth 500 to 5000 dollars and I got $10.00 each.

Good Luck in the future.
