I had been hearing of all sorts of media blasting and kept hearing about soda blasting. After looking around on the interweb I found a home made one. These guys just stuffed a hose into the box of baking soda. I took a nalgene bottle and put a port in the bottom of it to feed the gun. Real easy stuff.
So I figured I would try it out on the wheels. I used 100psi and I am amazed how good it took off the paint and wasn't so intrusive like sand blasting. This is the shit.
