Tutorial on cleaning with Deoxit (sticky in General Audio):
The Idiot's Guide to Using DeOxit (revisited)
http://www.audiokarma.org/forums/showthread.php?t=207005
These are tips from various threads:
Pot/potentiometers are the rotary knobs. If you use Deoxit D5 recommended to followup with Faderlube F5 to replenish lubrication.
Switches can be levers or buttons. Use Deoxit.
Sliders are knobs that slide like on equalizers. Recommended to use Faderlube only on these.
Some will recommend only Faderlube F5 or Deoxit 100% on rotary knobs to play it safe and not lift and damage sensitive membranes or coatings.
I don't use the Radio Shack twin pack of Deoxit DN5 and Gold GN5 because it's uneconomical. And the 14 gram quick drying breath sprays seem more suited for cleaning RCA jacks and connections rather than for fully flushing switches, pots and other contact cleaning.
So I prefer the 5 oz (142 gram) Deoxit D5 (which has more solvents for cleaning) and Faderlube F5 (for more lube) for just about all my cleaning applications. Just my preference.
Radio Shack DN5 GN5 twinpack about $15
Deoxit D5 5oz $13.99 Faderlube F5 $11.99 at Fry's
14 grams v 142 grams: You get 10 times more product for less than half as much more dollars.
