There have been a few threads describing the issue here, but never a good "solution". Many of the pots I'm getting in the mail these days are a little tough to turn and seem coated in a sticky residue. IMO, a pot should turn freely without much effort. So, I'm asking you all here, and this may open a debate or not, what would be the best way to clean a new potentiometer to get rid of the stickiness?
The old engineer's adage "if it doesn't move and it should, use WD40". I've opened up a few pots and cleaned it with a small burst of WD40 and spun it a few dozen times and it makes a HUGE difference. There's some debate on other forums whether or not WD40 is a good long term solution. I guess my follow up question is should I use regular WD40 or do I specifically need contact cleaner to preserve the resistive surface inside?
