This might be the most ridiculous question

While I'm waiting for a flywheel re-surface, the torque tube's driveshaft splines are getting rusty (car is outside in a tent-garage and it's pretty cold out). Before installing the clutch parts, I'm supposed to put MOS2 grease on the splines. I suppose I should clean off the surface rust that has formed first. Question is, with what?

If I use, say, WD40, would some of it remain and interfere with the MOS2 grease? Oh man, this sounds really silly lol

Wire brush does the trick well.

Not silly at all. It's the little details that add up and make the difference between and old car that runs ok and an old car that runs like new.

Whenever storing steel parts like that, coat them in WD-40 or other oil so they can't rust. But if it's already rusted, then I'd put a little Rustoleum rust dissolver on there and wire brush it clean (or try just a wire brush first to see if that's all you need). Then coat it with WD-40 until you're ready to use it. Then, once you're ready to use it, clean off the WD-40 with brake cleaner and a clean brush, and then use the moly. Use the moly very (very) sparingly, or else it can spin off and ruin your new clutch disk.

You probably won't find it but Corrosion X works well.

Tektyl 846 works well too.......it's like cosmoline

This is if it's sitting for a while. And of course a glob of grease works and is probably the easiest to find.

Thanks gentlemen. All I needed to know. Also thanks for the tip on using the moly sparingly!

wire brush to get the big stuff off.
then get a piece of green scotch brite, spray the shaft with WD40 and scrub between the splines, this combo knocks away surface rust like nobody's business.
clean off with brake cleaner and clean cloth/paper towel and then re-WD40 or apply grease to prevent further rust.
