So I've heard a lot of good things about this Sonax stuff from BMW guys, and figured I'd pick some up at the local retailer and try it out.
Well, this stuff is nothing short of amazing. I literally spent less than 30 seconds with a wheel brush on the inside of the barrel, and did not TOUCH the outside of the wheel (though it wasn't bad to begin with like the inside), and only the super stuck-on stuff is still on. Pics (last one is blurry, I'll grab a better one later):
Now a small bottle is 20 bucks, and only does 2 sets of wheels (big container is 100 and does about 20 sets), but the results I found were worth it. Remember, I spent less than 30 seconds agitating the inside barrel with a brush, and did not touch the outside. Had I taken off the wheel, I would have made these wheels look brand new. Oh yeah, the stuff also sprays green but turns red when it binds to brake dust.
