    This is not specific to Teles, but I figured I'd get a better than average answer here. What's the best way to clean a pot (volume) that makes a bit of a "scratchy" sound when the volume knob is turned at a certain point in the volume range?

    Cheers, Jared.

    get some Caig DeOxit spray, open up the control cavity so you can spray inside the body of the pot, and give a couple shots into the body while rotating the knob from 0-10 and back. I used to use automotive electrical cleaner (the quick-dry stuff) but I have heard that it can dry out the pots and cause them to prematurely fail. DeOxit contains a lubricant that helps your pots stay alive longer.

    Thanks!! I knew I'd get a reply here!! It's actually for a pot in a 60th Anniversary Les Paul R9 that I bought last winter. It's still under warranty, and I could take it to the store to have them do it, or I could do it myself, and not have to wait days, or possibly weeks to get it back.

    Do you know where I would buy that spray? An automotive store, or hardware store?

    WD-40 has an electrical contact cleaner that works pretty good for me. Got it at Home Depot. Use Gregulator’s method.

    Plus you end up with lifetime supply of cleaner for later use.

    Saves time, money and aggravation :)

    DeOxit is harder to find since Radio Shack went out of business. You can google Amplified Parts and order it online, or if you're lucky enough to live somewhere near a big box electronics store like Frys Electronics you should be able to find it there. I think Guitar Center stocks it too.

    I did Google it, and two large guitar/amp shops near me carry it. One being the store where I bought the guitar.

    This is something the store should be able to do while you wait.

    Yup. Takes less than five minutes, including removing and reinstalling the control cavity cover. Have them clean it for you and let you watch (under warranty, of course), and then buy a can of DeOxit on the way out the door.

    I'll ask them about it. $7500 guitar, less than 8 months old.

    I made my own from a piece of aquarium tubing


    P1012015.JPG

    but more importantly and with less wastage I use a # 10 hypdermic syringe and inject the De oxit into the pot it uses less cleaner and no over spray , same with cleaning jacks I use a q-tip soaked in De-oxit and swab th the jack contacts, also a 1/4 inch jack that has been covered in de oxit and exercise the jack( plug it in and pull it out.)

    Conventional wisdom is that the oil residue WD-40 leaves behind will attract dust and make an even worse problem. Pros use zero-residue contact cleaner, but that's not as readily available, and more expensive, and is more for switch contacts than pots. I've used WD-40 without any problems, and if it gets even gunkier later, well, I know how to safely open up a potentiometer and de-gunk it, so I don't worry too much. Tuner cleaner and De-Oxit are pretty much the same thing and they work well. In any case, a little goes a long way.

    WD-40 will gunk it up and require you to use it more & more often as it gets gunkier & gunkier till it's just a filthy slimy thing you won't want to touch. Doesn't sound like much of a solution, does it? Just get the right stuff to begin with.

    BUT - a new R9 shouldn't be having this problem to begin with...Gibson strikes again.

    Heard the problem with WD as a lube is bad due to the fact that it evaporates over time... either way should use what the pros use... thanks

    Every time I use this stuff, the pot becomes a low-friction wonder that changes position with the greatest of ease. I don't like that. Maybe I'm doing it wrong, if so, somebody help me :confused:
    Get a warranty service, is my vote. Deoxit isn't cheap up here. My can works great on switches, though.

    And WD stands for water displacement, so it's not a lubricant after all.

    Agreed. I'm going to call the store where I bought it today (they also apparently sell the detoxit stuff) and see what they say about an on the spot cleaning. Otherwise, I'll just buy a can and do it myself.
