This subject has probably came up at some point. But I just found out about this combination....now do keep in mind. I'm thinking of heavily damaged / unidentifiable type coins. Drawbacks? Thoughts?
So you mean soaking the copper coins in the WCS liquid? It's PH is around 3.5 so it is acidic enough to clean/brighten copper but the smell will make you hungry for a steak - just use ketchup, it's about the same PH range, it will give you the same results, and save you money as you'll only want an order of fries.
