Keep in mind that the problem with pots is build-up of fluff... and some of that cruft comes from wear and tear of the control itself; which means you get carbon dust building up inside, on the wiper and track, affecting the resistance.
The idea is thus that a small amount of WD40 will get to this and remove it from the wiper path and wiper contact, while leaving the track generally unharmed- it's easier/faster to dissolve a powder than it is a solid block of something!
Yes, drenching things in WD40 won't do them any good, but a little bit probably won't hurt.
