Thanks. So does acetone remove it after you are done etching? And does
anybody use Tinit?
I've found that while acetone removes the toner, it also tends to
stain the board. I've used very fine (1000 to 2000 grit) wet/dry
paper which works reasonably well. It also cleans the board for the
next step, which is using the MG chemicals tin plating solution.
Please note that this is NASTY stuff, that you want to use outside,
and not allow anywhere near food. Wash your hands afterwards, use
gloves, etc. Dedicated trays....
(and that's from reading the label).
