See if you can find a slurry blasting company. Basically, they use recycled crushed glass and water to blast. This creates very little dust, does not waste as much media, will not warp the metal (in your case not issue with wheels). Soda is not really aggressive enough to use on wheels and can lead to paint issues, also it leaves a very smooth surface. You want a little roughness for the primer to "bite'' into.
I wish you were closer, I have a slurry blaster and would gladly do them for you.
