I found this useful.

Has anyone tried cleaning the rear wheel rim with a high pressure cleaner?
I spent about 40 mins trying to clean it while it was off the bike... I did a 60% decent job and mostly just got a fuzzy head from petrol fumes, and petrol smelling hands.

You only need to remove 4 nuts! :D

Dont' use petrol to clean the wheel! Thats very bad.

Use Kerosene / Parafin if anything.
