I’m pretty sure that this is a basic resolution, but just want to through it out here. The volume knob on my T5S has a strong tendency to be noisy. When it’s acting up, just touching it is all it takes.
So, I have some DeoxIt. I just pull the knob off and spray that in there, correct?
Wait, not sure if I understand correctly: if "touching" the pot (metal knob or not?) silences your noise, then you have a grounding problem, and this has nothing to do with a pot's innards. DeOxit is marvelous stuff for cleaning connections, but if what you describe is the case, you need to dive deeper:
1. Is the noise you hear when plugged in with hands off all metal parts? Then when you merely touch the vol knob that noise goes away?
2. If the above is true, will touching another metal part silence the noise?
3. If the knob is not metal, then is turning the knob inducing scratching noise, or maybe lots of turning silences the noise? ...if so then here is where you do, indeed, have a dirty pot whose guts could use a spritz of DeOxit. If this is the case, spraying through the top of the pot is a tough call as to whether enough solvent will get into the pot such that the wiper and carbon trace on which it rides will get cleaned off. The proper method is spray through the lugs area to ensure the insides get fully cleaned and coated.
