Noisy crackling volume pot on amp?

[Linus27]

I have a Genz Benz Shuttle 6 amp and the volume dial crackles when I turn it, mostly from zero volume (7 o clock) up about 4 notches (9 o clock). I am assuming that its just dirty. Is there any thing I can spray onto it to clean it?

If yes, whats the best way to go about this? The volume dial cover can pull off revealing a peg with a nut on the end. I am sure if I undo the nut, the peg will fall into the amp casing. So is it better to see if the amp cover comes off and approach it that way?

Any help really appreciated.

It's better to get access to the body of the pot in question - there's usually a gap in the casing where you can squirt in some switch/contact cleaner. Servisol Super 10 is the cleaner I use, there may well be other products but that's the one I know and trust. Squirt some in the hole then turn the pot back and forth several times to (hopefully) work the magic.

Take the cover off the amp, locate the noisy pot, and use the "straw attachment" to spray a little Servisol inside the pot.

Most people would call this ''snake oil'', but I think it actually works, it apparently fills the microscopic pores in contact surfaces making them one, good for jack sockets etc, not sure its meant for Pot's though.
