There are some components that can be damaged by water and/or cleaning 
detergent.  For example, you may need to re-lubricate the bearings of 
variable capacitors and other components with moving parts.

If water gets inside a power transformer it can be hard to dry it out.  
A method some use is to power up the transformer with low voltage, 
perhaps from a variable-voltage (Variac) transformer.  Make sure the 
power transformer has a big enough load to cause some self-heating 
(perhaps the filaments of the equipment that the transformer is 
powering) and leave it for a few days to dry out before applying full 
voltage.  Place the equipment in a safe spot (concrete floor) and make 
sure it is well-fused in case a short does occur.
