[R-390] Cleaning Potentiometers

[Brad Huff]

Hello,
I apologize if this has been discussed before but sometimes it's the simple things like this that can cause us the most trouble. What are you guys using to clean and take the noise out of carbon potentiometers? I've heard horror stories about the different brands sold for this purpose. I've even heard of the value of resistance changing after using some cleaners, this in fact has happened to me and I'm still waiting to see if it will return somewhat to what it was before cleaning. I've been told that the stuff Radio Shack sells is not good for carbon pots and that the mineral oil in it will attack the carbon element. Any thoughts?-Brad
