for the whells try some neat tfr or some diluted whell acid, should shift all that better than APC because APC is better at de-greasing and general cleaning, TFR will attack the crusty backed on break dust/road grime, after you've got them how you want them give them a really good rinse off then wash with some soapy water well and rinse again, dry off and give them a good polish by hand then seal and wax them, they'll stay cleaner for longer and the sealant and wax will stop contaminents bonding to the surface.
