That's why I parallel ported the T/C's. Now I can use a calibrated hand help thermocouple and plug into the T/Cs on the oven. If they're within about 3 degrees of each other, then they're considered within our specification. Paper work on the hand

If your pots are open you then just need to dry them. Don't hide them. Are they rated for water clean? If not hand solder after cleaning with no-clean wire. Hand cleaning with IPA is dangerous - you really just push the flux around and don't was
