No...running it though your dishwasher is fine. The bad part is having electricity running though it when it is still wet. So make sure it is dry.
Did you know that most electronic repair shops usually run the parts though the dishwasher. Radio, voltmeters, computer motherboards, but nothing with a capacitor. I use to work at calibrating house they did it all the time. It freaked me out the first time I seen it.
Also it works great with remote controls. Take the battery out, disassemble it and run it though the dishwasher. I have a little basket for little items that is perfect for sticking in these disassembled parts.
