ok .. 17% peroxide ..
34 % muriatic acid ..
mixed 3 : 1 ..
never seen copper come off a board that fast .. ever ..
did it outdoors .. respirator .. goggles .. gloves ..
anyways.. should the solution be bubbling even AFTER I take the
board out ?? whats it mean .. I put more 3 % peroxide in it ..
calmed it down .. is it safe?
