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...

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
