I find the grooves on the OEM 19s a PIA to clean, then on top of the the little gap between rims annoying as well. I looked for awhile and counldnt find a good tool for cleaning them. Then one day walking around our local buchheit (farm store) I ran across the perfect tool. Its amazing how well it works and only 2 bucks..

Thanks for the recommendation. I find that it takes me about 50% of the time to clean the wheels and the other 50% to clean the rest of the exterior of the car. Anything that can help speed up cleaning the wheels is a welcome addition.
My local detail shop sells Sonex Full Effect wheel cleaner. Spray on and hose off, and it really works well. Handles 90% of the wheel dirt. I'm sure there is a similar product you can get at more places, but till I find it, this works well. It's worth trying a bottle if you can hunt it down.
I have the wheel cleaner and 2 types of brushes from Griot's Garage. Spray on, let it sit, then blast off with a full-jet setting on the hose. Finish with the brushes and a quick rinse.
+1. But you don't have to hunt it down, just use your keyboard. It's available online from lots of places.
Amazon has them for $6.96 + $6.26 S&H for 6 of them! Buy a couple for yourself and sell the rest to your friends. Amazon.com: 2/1 Detail Brush, Pack of 6: Home Improvement
