Water washing of electronics is standard procedure in most industrial
electronics shops.
At Tektronix, HP, Military and most large industrial electronics repair
houses. We use dish washing machines or even pressure washers for
cleaning. Ultrasonics in some cases.
The trick is to know what needs to be protected or removed prior and how
to properly dry a unit prior to power up. Any modern surface mount
board was likely washed in original production.

While they didn't use bathtubs, the HF shop across the parking lot from our
VHF/UHF "and more" shop, they did hose down and let air dry KWM-2
transceivers and accessories at Incirlik AB Turkey. The gear came from
remote sites around Turkey without maintainers. The users didn't care
about how dirty the gear got, only that it worked.
There was no electricity involved until after gear was thoroughly dry.
After that, they performed the required periodic maintenance inspections
(PMI's) to ensure it was ready for future deployment.

Thank you, Kurt.? Brilliant advice/great reminder about dust.? Much
appreciated.
I grew up on rumors about how the Henry Radio repair shop would take a
Collins S-Line in for repair, throw it in the bathtub, and take a hose
to it.? It always amazes me how "we as a society" somehow automatically
assume water is bad near "electricity" without knowing more of the details.
