Oiling or greasing the jog wheels/e-dials?

[Matjazz]

Some time ago I had my K220D in a cave and was too confident about it's water, dust etc. resistance. The result was a sticky back dial and I was quite annoyed with it. Took the camera to the service and they said they found sand and of course cleaned it. Now the dial feels better but still sticky and I can't help to think that some oil or grease might help. On the other hand it might do some damage to sealing and might be conductive. I bet there is something out there that is safe to use. What would you recommend?

Any grease or oil will definitely trash the dials. They have to be perfectly clean to make contact properly.

SuperLube is a silicon based product that does amazing thing. I never tried it on a command dial, but I would be confident using it. It won't damage rubber or neoprene seals. You can get it in syringe type applicators. And it is dielectric.

I have no idea whether it would work, but RadioShack sells something called like "tuner lubricant" made for devices with contacts. perhaps worth talking to them about.

Oh, man, be careful with that stuff in the spray can. It can go everywhere when you press the spray tip on the can and I'm not really sure what it does to different plastics over time.

Well I've had several Pentax digitals open to replace shutter switches. There is not one drop of a lube on any of the rotating dials. Most of what I have read, says to keep the contact surfaces as clean as possible.
I had a problem with my DS dial. I took the top off and cleaned the contacts with a swab and contact cleaner. Works fine now. For supposed non oxidizing metal, it sure had a nice layer of gray crud.
