How do we clean potentiometers??

I tried to clean the pots of my Russian Big Muff wihitout opening it and it worked yesterday, but today looks like it is dirty again :eyebrow:

I also opened my MOTU 828 sound card, sprayed almost everywhere, worked yesterday, but is dirty again today :eyebrow:

I used Asalco Cleaner and Lubricant "cleans and lubricates electrical and Electronical components"

It is contact cleaner from an electronic/audio store. I am shure that this stuff is good, i even asked the guy if it was good for cleaning pots.

What exactly are you spraying? Did you spray into the pots?

i sprayed from the "top" of the pots, just by removing the plastic knob. It worked for 2 pots out of three with my Big Muff.

AS you cannot only remove the plastic knob for the 828, i unscrewed the top, and sprayed everywhere on the pot, with the intention of getting the contact cleaner inside the pot!! ;)

The purpose of this thread was do wkow, how do we spray inside the pots!!?? Do you have to open the pot itself? Is the contact cleaner supposed to get inside the pot from the "top", or you have to remove the pedal's cover to spray from the "inside" of the pedal?
 
Technically, some brands of pots can be 'opened' (which requires opening up the pedal, bending back some tabs, and being VERY careful not to damage or upset the phenolic wafer inside). I know of at least a few people who have cleaned pots in this fashion.

However, I suspect fdeck might be right with the Big Muff. Especially playing in smoky clubs or just having dust around, pots wear out on occasion. I, for instance, need to replace the pots in my Big Muff, because cleaner does nothing for them anymore. If enough dirt and grime and dust gets inside the pot, it will eventually either a) mess up the resistive element or b) just never come out, and no amount of cleaner will remove it all.

So down into the shaft? If those knobs are what I'm thinking the spray would have just come shooting out the other end of the shaft inside the pedal - the shaft is just a tube.

You've gotta get the spray onto the resistance track and wiper, which is inside the main body of the pot. Usually there's a little notch with just enough room to poke the tip of the spray can tube into and squirt some in there. However, some pots are all sealed up.
