Hi we have a new 220 M sport with 18“ M light alloy wheels Y-spoke style 975 M Bicolour. Can anyone suggest the best option for cleaning the wheels, as already seeing a build up of dirt, looks like brake dust after only 2K miles. Wheels have been cleaned a couple of times with a general Wheel cleaner but i dont want them to get to the point that i cant remove the dirt/ brake dust.
 
	any help or guidance would be much appreciated
