Hello Jeremy, A bit of contact cleaner/isopropyl alcohol on a cotton bud is perfect for cleaning the wiper and board, followed by a drop of inox/super lube.

I am sure you already know this, but, try to avoid adjusting the knobs under power,......adjust the knobs, try the car, stop/adjust, and try again until you are happy,......the "pots" are quite sensitive, and are susceptible to failure , if adjusted under power.

Cheers
