Water washing of electronics is standard procedure in most industrial 
electronics shops.

At Tektronix, HP, Military and most large industrial electronics repair 
houses.  We use dish washing machines or even pressure washers for 
cleaning.  Ultrasonics in some cases.

The trick is to know what needs to be protected or removed prior and how 
to properly dry a unit prior to power up.   Any modern surface mount 
board was likely washed in original production.
