This is a good point for the masses. I've done enough design(20+ years)
so transformer design and the like are familiar to me.

But then again I've cleaned boards in the dishwasher! Works great too.

Also while In has I made a business of salvaging and repair marine gear
that had been dunked in salt water which is very nasty to electronics.
Part of the repair process was to very throughly wash out the unit in fresh
water as no salt could be left (it's very hydroscopic) then repairing any
damage if any. I've had marine equipment work better for this due to
residual salt and dust accumulated being cleaned out!

A good temp to bake at is just under 200f, it's slow but works and most
plastics and semis are ok at this temp! Do monitor it though.
