Keep in mind that some faders shouldn't get lubed...or sometimes it's the other way around, cleaning with the wrong product removes the lubricant.
For non-lubricated faders, I've used the Caig DeOxit D100L...which has no solvent in it, like the DeOxit D5 does. It cleans, and leaves a very light film which acts as a lubricant. I've never used their fader lube, because it's only for specific faders that need that specialized lubricant.
These days...I use the Caig stuff primarily for contact cleaning...jacks, plugs and some switches...but for more critical cleaning, including faders...these days I prefer to use a product I discovered a few years ago called Contact Re-Nu & Lube, MS-738 from Miller-Stephenson. Its not easy to find, and it cost quite a bit more than the Caig D100L, which isn't cheap either...but the MS-738 is superior to the Caig stuff, has less detrimental effects, and is intended for delicate electronics (they use this stuff for hearing aid cleaning of contacts). It leaves no obvious residue, but it cleans great and there is a thin lubricant that doesn't over lube faders, like some lubes can.
I pro studio guy turned me on to the MS-738...and he said he's used it on everything, and you could spray it on liberally...unlike the Caig Deoxit which you need to use very lightly, as it will leave a gunky mess if over applied. With the Caig D100L...you apply it to clean, and then you wipe it off...and leave the smallest amount on the contact points.
