Cleaning metal... (Hey! LarryF)

[Richard Wagner]

Hi all.

This sounds amazingly like it could be what I've been looking for!

But Larry, you didn't mention what voltage you applied with your battery
charger and how many amps actually flowed through the "soup."

I'd like to try this with a power supply but it's only fused at 3 amps.
(I have no battery charger.) 

Also, I've been experimenting with a small plating kit from another source
to see if I could do small parts or maybe a pedal or two.  I'll have to
look into the "Caswell" kit as well and compare the two.

Thank you both for the info.
