So far as I know, you should not clean the electrical portion of any sensors.

On the following link about 3/4 the way down is a picture of the inside of a "variable resistor". I would suggest going to a second hand store and buying an old radio or something with a volume control like this, then measure the resistance (ohms) as you turn it back and forth using the middle contact and one outside contact.

Then take it apart and clean it with your cleaning solution, let it dry, then put it back together and measure the resistance again. See if the cleaning fluid damaged it.
