this takes me back some to a customer that was making TV converter boxes
(legit). Seems the boards were assembled in Mexico and then tested in
Texas. Then would fail after a few hours... seems fungus growing on the
board from the bad water (recirculated and reused excessively) used would
cause high resistance shorts that would affect the microprocessor crystal
clock. The fix was a was a wash in good Texas water.

Actually, a clean board has a lower fail rate as the cooling is better,
no dust or grunge.

Case parts can also be cleaned that way if they fit, me I take them
out in the driveway and use the hose and a bucket of soapy water.

With care you can clean most anything with soap and water... assuming
the object itself isn't water soluble. ;)
