I just got a new BMW Z4 with Cerium Grey wheels. They have a matte finish that gathers brake dust very readily and it sticks to them more than to shiny finish wheels. I’d like suggestions on what would be best to use to clean them and particularly to coat and protect them so they’d be easier to clean in the future. Thanks in advance!
I’d try Brake buster as it is pretty mild but has some bite. I’ve read a lot normal coating won’t change the look a lot and wheel coatings are suppose to be better for higher temperature.
Dr Beasley’s has a matte sealant for wheels which I would use for maintenance and would use C5 which Gtechniq says is suitable for matte and satin wheels.

Griots Garage Wheel Cleaner (the green one) is a really mild wheel cleaner and does a great job on that sticky BMW brake dust. When I owned a 435 MSport, it easily cleaned up the wheels.
Agree the coatings shouldn't have any affect on the appearence. The wheels on my car a satin gray metallic and when I used some left over Gyeon Mohs EVO on them, I noticed no change in the look of the wheel.
I'd say coat them as a first pass - of the Cerium is exactly like their Cerium trim, love the finish but it shows water spot very easily
Re: Brake dust.
To eliminate that brutal, wheel-destroying, Brembo brake ash, I've been using these pads for years now.

As long as you're only street-driving, these work great. Even on my 4600lb. Charger. The 6-piston Brembos are dust generators.
