I don't think the details are pertinent so I'll just get to it. I applied too much voltage to a diode bridge which I didn't build that was intended to withstand high heat. I am trying to replace the bridge and I realized my digital soldering iron won't melt the stuff at 850 *F. I know I can just clip it but I would like to remove all that build up, if possible. What could they have used and should I re-attach my diodes with the the same? Thanks.
