I've always had good results using Pro-Gols or Deoxit in open pots. I don't know what a "Command 8" is, but I imagine the pots may be sealed? If you canm get the spreay in there then I would certainly go for it. I like the Pro Gold (mostly lubricant) for lighter stuff and if that doesn't do the trick I'll go to the Deoxit.
You can spray if you wish and it will help, certainly in the short term.
You say the pot is 'reknowned' for getting scratchy, this sounds like a design fault as even the 'cheap' ALPS pots are usually good for 7 years or more of 'twiddling'.
You could check if there is ANY DC appearing on the pot, either wiper or top end. This will accentuate the crackle from any dirt on the track.
