When trying to make a pcb I messed up on the toner transfer... I have grayish traces on the pcb, and some of them didnt even transfer. I know you can supposedly get toner off with lacquer thinner, but i couldnt find any. Will paint thinner work? The pcb is fine, it has some white paper on it though too.. I have acetone too :)
Also, when ironing with photo paper, something melted and is all over the iron. Is this potentially hazardous? Probably not good to breath in.. Any ideas on how to clean that off and to prevent it from happening?
