What to do when Wheel Brightener is not enough?

[MrC]

I detailed a 2001 Mercedes today and the brake dust on the front rims were baked on. I was on a tight time schedule because she needed her car back. I sprayed the rims with a 4:1 ratio and that helped with the face of the rim but not on the outside edges and inside the spokes. I tried a 1:1 ratio and stiff nylon brush but that didn't really do anything. I didn't try it straight because I figured if a 1:1 ratio did very little going straight would do very little. Because I had to get the car back to her I told her that I would try again when she was free. She said I didn't need to, but I insisted because it really annoyed me that I couldn't take the break dust off. I'll post pics later tonight. Any suggestions.

Believe it or not you will need a aluminum type acid cleaner for that brake dust and a brush to work the product then you will have to neutrilize the acid cleaner after the rinse with a alkiline base cleaner after all of that a good protection over the wheel like wheel wax

NOTE: If the brake dust have etched the wheel just do your best and advised the customer GOOD LUCK

Thanks for the help. Any suggestion on products?

You can see how the face of the rim looks good but inside the spokes and outside edges have baked on break dust.

I have used Never Dull for this type of situation. It was not as bad as those though.
