 I always wonder if it is ok to clean a dirty bearing hub, like with WD 40 or
Kerosene. Will that screw up the lubrication for the bearings?

WD-40 is a water displacer that leaves a gummy residue. Kerosene will
float off lots of crud and leave a bit of lubrication. So the answer is
"It depends". But WD40 is rarely a solution unless your problem is
displacing water (or lubricating cutting tools for aluminum).

I use it all the time on dirty bearings, but you'll have to re-lube them
after cleaning.

And in addition, do not spin the bearings with compressed air.
