Ok so 4 weeks ago I decided to buy a metal detector, I bought a X-terra 705 and hit the beach .
I got 10 or $12 dollars in gold and silver coins, only thing is most of them are stained black.... so I get online looking for some way to clean them.
I tried vinegar, salt , baking soda and worked my way to caustic soda .... I might as well used water lol , so I get on line and see electrolysis.. the answer .... so I thought... I made a bath and tried it out, some sites say the negative for the coins and some say positive.
I thought Ill try both... I let them go for about half an hour only to find the clamp had dissolved lol , no big deal I put another one on and left it again, only this time my black $2 coin was bright pinky copper colour ..... it must of worked to good so I put a twenty cent piece in and half an hour later it was clean but where the clamp was it was stained a copper colour which u guessed it.. wont come off ....
SO I could use any idea for cleaning them as long as they dont come out pinky / copper colour!!
