I have just got around to cleaning the rust on my spindle today. Here is what it looks like now:
What I did was apply a light amount of WD-40 to a Scotch-Brite® Heavy Duty Scrub Sponge and gently touched it against my spindle while it was rotating and it seemed to get rid of the rust pretty quickly.
My question now is, should I apply the Boeshield T-9 using the same method: Applying it to a rag and rub it against the rotating spindle, or should I apply it to the spindle when it is not moving? I would think the moving spindle would help produce a more even coat and help air dry it at the same time, but I am not familiar with T-9 so I may be wrong.
Another thing is do I need to remove the WD-40 completely before using the T-9 or can there be a small amount of WD-40 still on the spindle?
