Ron, the buffet of products that Deoxit offers can become confusing.  F5 is Faderlube with a solvent to clean and a 5% solution of lubrication.  F100 is 100% lubrication with no cleaning properties.  So I use D5 for switch contacts, F5 for potentiometers and maybe add a drop or two of F100 (mine is in a needle dispenser) to keep them smooth.

Mike's TrolMaster might be found on eBay or a lucky garage sale find and later versions were called a goesinta,  Below is a link to all the details:

Mark Oppat sells a cleaner only and a cleaner with lube that I'm sure is cheaper than Deoxit. I do google searches for the best Deoxit price and usually find them at guitar/music shops online for the best price.
