Same here, in fact when I had a dishwasher it was standard procedure.
Now I have to do it by hand!  I normally scrub with a tooth brush.  I
even use soap or some type of spray cleaner like Fantastic.  They get
rinsed with hotish water.  If the board has a lot of places to trap
water, I'll blow it off with my compressor, or R134a (canned air).  Then
it gets stood up on an edge in front of a box fan, and I'll rotate it
every so often.  Sometimes I'll leave it over night, but really a few
hours is all it takes.  Sometimes I'll put stuff in the oven.  I've even
done a  PC power supply or two this way, after I've taken it out of it's
chassis.  I'll get just about anything wet, that I feel I can get dry
effectively.
