Must have been an old penny. The US mint stopped making solid copper pennies in 1982.

Don't know what year it is , the KG12 dissolved it and best of all it doesn't stink or destroy bores if left in them.


I used to use KG12, but if memory serves, it etches the bore.


Nope no ammonia


Must be thinking of something else I used in the past. I will give KG12 credit, it's a good copper remover.


It's the best , nothing even close. I use Wipeout when I don't want to use brushes and patches.
