Can Wd 40 Clean Potentiometers?

Yes, I have been using WD-40 to clean potentiometers for 50 years with good results. My experience has been that if WD-40 does not render a pot serviceable, usually no other cleaner or solvent will do the job either. It's time to replace it.

How do you clean and lubricate a potentiometer?

After you have cleaned it you should put in some dielectric grease. Isopropyl alcohol works well too - You can submerge the pot and give it a good soaking, then just turn the wiper backward and forward a few times to make sure it's well worked in.

Can you use WD-40 on pots?

No, absolutely dont use it. Go to any store with electronics supplies and get electronic cleaner or tv tuner cleaner if they have it. Spray in the pot between the lugs and twist the knob back and forth several times. Repeat as needed.
