I had that same problem trying to remove that baked on brake dust. I thought it was brake dust but it actually was the alloy starting to pit. I used my commercial wheel acid that detailers used and I could not get it to come off. I did try using steel wool and light sand paper and it didn’t help that much. This is how I washed my wheels and tires in this order.

Pick up the following items: a bottle of Bleach White (at any auto parts store) or commerical grade white wall cleaner from a car detailing supply company, a regular stiff brush (square shape with a handle on it), a brush that is cylindrical with a handle on it, a grill scrapper brush with a handle on it, Latex cloves (optional),a mesh bug sponge, a can of wheel wax.( any brand)

2. Spray wheel and tire with bleach white 10-15 squirts
3. Let is sit for 15 seconds.
4. Take the square brush and brush around the wheel crevices, and tire.
5. Take the grill scrapper brush and brush hard around the white walls to make them shine.
5. Take the cylindrical brush to get in those tight crevices better
6. Take the mesh bug sponge and attack those tight crevices even better
7. Spray wheel and tire off.
8. Apply some wheel wax. I prefer American racing wheel wax $12.
9. Take a microfiber rag after the wax has somewhat hardened on the wheel and proceed to wipe it off.

Note: that brake dust will stick to wheels a lot more for a while. Just take a rag about every week of or every other week and just simply wipe then off.
