For a car that hardly ever requires braking, I sure get a ton of brake dust! I bought Meguiars All Wheel cleaner today (here), but then decided not to use it because I don't know if the wheels are factory coated or not. The bottle was very clear NOT to use the product on uncoated aluminum wheels; they have another product for that (here) Anyone know what I should use? Or is there a better way to clean them? Has to be pretty easy or I end up never doing it...just reality. Thanks!
