The circuit boards I have must be different from regular copper plates
because there is something on (or in) them that will not clear up with
brasso, no matter how much I rub. What I am looking for is an elixir: I
drop the circuit boards in the elixir and 30 seconds later when I pull them
out they are as shiny as a mirror. No swearing or cursing involved!
