My LCS tests everything he gets, thats great for me as I'm sure I'm getting good silver from him.
Problem comes when the red residue is still all over the Bars/Rounds.
Iv had some luck with Vinegar but it still leaves a slight redness, will Acetone get it all off?

Someone on another forum suggested using Bicarbonate of Soda in a paste form rubbed onto the Round.

I tried it using a toothbrush and it worked, took all the Red Residue off.

Dont know if I would try it on anything like a coin, dont see any scratches on my rounds though,
