A friend has one of these that i had talked about borrowing.
What media/solution did you use?
How full did you fill the bath? Coins on coins or a single layer? 3 or 5 or 10 layers thick? Roughly?
Thanks!!
I have a Hornady sonic cleaner...I used the Hornady solution with DI water per the instructions, I didn't have a lot of coin...maybe 3 dozen...they came from a vehicle drink cup holder and they were pretty nasty...gunked up with dried soda and cigarette ash...The bath can be set for intervals of 90 seconds, after each 90 seconds I stirred the coin in the basket. I did this maybe 5 or 6 times. The coin came clean enough to spend.
I have tried it on silver quarters...with not impressive results...the tarnish was still there, the flat areas were still flat but the smoothed/polished areas were pretty shiny after running through the sonic bath.
If you got some really nasty coin give it a shot....Good Luck.
