Homebrew PCBs

I'm neither particularly meticulous, nor do I use solvents :-)

I've found fine grit wet and dry paper and normal detergent (for  
dishes) cleans the copper perfectly, and leaves a surface to which the  
toner adheres very well.

For taking off the toner after etching, exactly the same process - I  
just scrub the toner off with the same bit of wet and dry and soapy  
water that I used to clean the board.

Pinholes can still be a problem, I've found it depends a lot on the  
paper (some paper seems terrible for it, with others there's hardly a  
problem), and 8/8 is as low as I tend to want to go (10/10 is an order  
of magnitude easier to do than 8/8, I find. But then again, I do use a  
clothes iron to transfer the toner).
