Best way to clean and store 8 3/4?

Best way to clean everything up?

My plan is to sell the axles, brakes and housing so I figured I would just pressure wash them and wipe dry maybe some wd 40 on the bearings.

The center I'll use as is OR rebuild once the gunk is off. I was thinking of pressure washing the center then spraying it liberally with WD 40 or the like then bagging and store it in a sealed 5 gallon bucket it till I'm ready to use it. (6 months to a year.)
