I washed a Colour Classic board in the dishwasher, dried it and then let it sit buried in rice for about 24 hours. It worked extremely well and I might end up doing that with this Q700 board if my attempt with isopropyl alcohol doesn't work out. I would consider it a 'last-ditch' effort, though. I think there are quite a lot of variables to consider when using the dishwasher. I didn't bother removing the CPU, but it would make sense to if it's socketed.
