[AMRadio] Best product for noisy potentiometers?

[Kimberly Elmore]

I have some noisy potentiometers on a Yeasu FRG-7700 receiver, along with a 
noisy RF gain pot on my HQ-170. What's the best stuff to apply to it to help 
clean and quiet these pots? I have two flavors of DeoxIt --D-series and 
S-series. Do I need the F-series for this, or is one of these a good choice, or 
is there something else better?
