Hello Guys,
I recently purchase the copy cad/zinc set and after doing a few items I have a few questions. I know theres no stupid question but these may be close.

First and biggest problem I have currently is a motorcycle axle I actually forgot about and when I realized it was in the plating solution I pulled it out rinsed it off and the plating got so thick the nut no longer fits it. Whats the best way to remove the zinc coating so that I can start over?
Second important question is that after noticing impurities in my solution I decided to filter it through some coffee filters, clean my tupperware and restore it all. When I filter the solution I'm getting a yellow sandy/very fine layer of particle on my filter. I'm almost sure this is the (Needed) zinc additive in the solution since it looks like what came in my original bottle. Is there another way to 'clean' the solution without using filters? I have read to do it through charcoal but what would I use other than a coffee filter?
I'm new to these forums but am sure I'll be here reading as much as I can to get this down pat. Thanks for any and all help on these matters.
