Definitely agreed on both counts Peter ...

BMW sells a wheel cleaner that is very similar to P21S which works very 
well, but seems to discolor the wheel over time (experience on cast motor-
cycle wheels).  I've had good luck with simple green as well.  I found 
some stuff at COSTCO called Grease Eater which I used to clean up a few
sets of Audi wheels not too long ago.  This stuff worked about as well 
as the BMW stuff, but it doesn't tend to yellow the finish.

HTH!
