I have yet to receive my car so I am not sure but it looks like a pretty straightforward wheel to clean. I use Klasse AIO followed by Klasse Sealant Glaze on my wheels which will make the surface slick. I repeat this treatment every 3-4 months. I use a sponge to clean the wheels with the same wash solution I use on the rest of the car's paint, except in a dedicated bucket. I have a paint brush in this wash bucket to get around the lug nuts, and other difficult to reach places. On my M5 wheels I used a painter's stick with a microfiber towel to clean out the groove in the spoke.
I find it very helpful to have a detailers stool so when I am cleaning the wheel, dressing the tire, and cleaning and dressing the wheelwell I am sitting down and comfortabale.
There is no cure!
