We have seen failures on a crystal oscillator when cleaned in our aqueous 
cleaning system.  As you mentioned, water entered through the hole and shorted 
something when powered up.  Apparently, any conductive liquid entering the 
component will cause havoc.  One possible solution would be to bake out the 
assembly prior to powering it up.  Although we opted to install this component 
and hand clean after the normal assembly process.
