Nobody likes dirt it seems. They like it when it is clean. That said, remembered seeing that Kathy Bates movie at 16 twenty years ago. Still a chiller!
Just remember... They wash them, usually in a water/alcohol mix before they pack em'. I've thrown boards in the dw before. No problems. The only boards I would put in are my own boards that got dirty from use in my home. I wouldn't put crud from someplace else in my dw. But if I do, I put it on a quick rinse cycle, no soap.
Nice clean up though. Can't wait to see the other board.
I've not put one through the dishwasher, but I have washed some as dirty as those in the sink. After washing I rinsed with some 91% isopropyl acohol to make sure all the water was out and then dried in the garage (summer in Texas is nearly as good as the oven) for a couple of days before applying power.
The good thing about that much crud is that you know the EPROMs didn't get enough light to erase....
