All advice appreciated. Trying to save $ 65.

Salt in the silt will be conductive, and would screw up the operation of
any analog circuitry (which there surely is) on the board.

Swish it (the circuit board) in distilled water, maybe brush it all over
with a tooth brush to get any clinging gunk off, then bake it at about
150 degrees for a few hours to drive out any water.

Then don't be surprised if it still doesn't work. You may not clear the
problem, or the problem may have damaged the batteries.

What Tim said.
In addition, you can use your Water Pik with a gallon
of distilled water to dislodge silt from between
component legs.
