Actually, yes, you can wash electronics in the dishwasher. But only stuff that won't be hurt by water, the PCBs themselves. Speakers, mic elements, mechanical stuff like tuning knobs and displays cannot. So don't wash your CB unless you disassemble it. OTOH, I've run cell phones through the laundry and they weren't ruined...
