    Next time something gets wet, put it in a pickle jar with a schraeder on the lid and draw a vacuum on it.

    Works very well for dehydrating phones and such.

    By doing that, you are boiling the liquid refrigerant, causing it to drop in temp.

    It will work, but simply removing liquid refrigerant from the tank works faster.

    Once the temperature stabilizes, remove the R22 AS A LIQUID.
