while D-143 is certainly an effective degreaser alternative to wheel acid, but not my first choice on powder coated wheels. If you are interested in a mild degreaser that you can use to effectively cleans wheels, tires, wheel wells, paint, etc. Optimum Power Clean diluted anywhere from 3:1 to 7:1 depending on how maintain the wheels are is a really effective and relatively mild degreaser. Another great cleaner that is mild enough to safely use on every surface of a vehicle and is nice because you don't need to wear gloves to use is Nexzett 1z Blitz APC. I dilute it 30:1.
