fingers and other plated boards

[Yggdrasil]

Hi Patnor
Thanks for the answer.
I did not mention my agitation, of course I have agitation
I'm using this nice little four port Sera aquarium pump.
I can keep 3 pots leaching and still have one spare for the stock pot
I was hoping that it was possible to leach out all the copper.
Some of the Ram sticks have quite a few through-hole plating which hold remarkably well together.
I can not flush them off with quite powerful water jets from a squirt bottle.
My guesstimate is that on some of sticks the area can be as much as a few fingers.
Oh well, I'll give them a couple of weeks more and then see how clean I can get them.

What about using h2so4 and fertilizer to get rid of solder and copper?
And yes it's also need too much safety acts working with h2so4 and filtering it is a nightmare,but weak h2so4 and fertilizer urea can work to get the clean gold ?
