WD-40

Doesn’t WD-40 just remove water and then it leaves behind some lube?

WD-40 can protect against rust and help prevent it, but I wouldn’t try to ‘fix’ rust with it.

whatisfear - Any oil is going to ‘add’ response. The trade off is that your bearing will last longer and spin more quietly. If you want ‘less response’ at the cost of a shorter bearing life and more noise, clean the bearing with solvents like mineral spirits and don’t add anything back to it. Most people find that a few drops of oil is well worth the tradeoff.

I’ve fixed 2 rusted bearings with it.
