Hi Andrew, I throw my completed and tested new boards straight into the ultrasonic bath, with plain water. I usually leave then there for 30 seconds. It removes any and all flux, even the flux left residue underneath the chips (on smt packages). It works great to remove the flus, even if the flux is not the water soluble type. It sure beats the heck out of drowning the board with toxic and expensive flux remover::> Enjoy.
