I have those wheels and my detailer hates them! They are so difficult to get into the nooks and clean. Mine have also got some defects on them as well as a little curbing so I'm going to have to just get them refurbished.I have the same wheels as OP, there is some corrosion in every "spoke" on the black surface in the corners. I'll try and get some photos, but any idea how I can get that off? It looks a bit like brake dust but it's very hard and baked on.
I use an EZ detail brush, a mitt, some light citrus degreaser, followed by regular shampoo for the wheels.
The bilberry wash is very good and does not smell too evil.
