LOL..M3 dual spokes are the same way, or worse.
Mine have slots that the brush won't fit into…about ¾" while it still base the big slots too.
It's a bit ****, but removing the wheels twice a year (I have snows but only use the M3 when I have to, like when daughter uses S6 and wife is out in the A5) and cleaning them helps a lot, plus Rejex or Wheel Wax keeps brake dust from sticking too badly.
Once that brake dust stays on more than a few weeks and combined with road dirt, chemicals, and acid rain etches the wheel paint and makes the brake dust very difficult to remove.
I've found that new or refinished wheels retain a lot less brake dust and are a lot easier to clean than 5-8 year old wheels even if the old wheels have been maintained well. If I can talk the refinisher into using it I like to clear coat with Imron or another aircraft-grade two-part clear epoxy or catalyzed urethane. Of course Imron has drawbacks, toxicity, etc., but I used it 30+ years ago on Datsun 280Z wheels and they still haven't yellowed in the Michigan winters.
I understand MB no longer uses ceramiclear coating, the one with the SiO2 particles in the top .2mm for a variety of reasons. Apparently more modern coatings are sufficiently (??) harder, isocyanate cross links, etc., but IIRC that's what was in Imron in the first place!!! FYI, I used a simple PreVal sprayer and mixed enough Imron to do the wheel and then cured it in an old kitchen oven at 160F for a couple hours.

Received my Wooly's Brush today. Can't wait to see how it works.
