Damp, drenched, or dunked?
If it was salt water I'd dunk them in fresh water for a bit.
I'd remove the covers and use a blow dryer, place near heating vents for a few days, etc. Airflow is needed for evaporation.
Oil steel, agitate rust, and re-oil, etc.,
But thats it....evaporation and tending to steel.
The effects of salt changes things, rinsing it clean a.s.a.p. would be very necessary.
I have run motherboards through dishwashers after spills, a transformer new or old, should be no big deal.
To be safe, once dry, power them from a gfi outlet and or a power strip with a breaker. Let them get good and warm for a long time to further expell any trapped moisture.
