Meguiar's Ultimate All Wheel Cleaner, G180124, 24 oz, Spray

This product works as advertised. It removes brake dust and road grime with minimal scrubbing required. Application is straightforward: spray it on, wait for it to change color, and then rinse off. The wheels were noticeably cleaner after use. A solid product for wheel cleaning.

This is the easiest and best wheel cleaner I've ever used. If you have baked on brake dust on your wheels this is the product for you. Simply spray it on and watch as it turns purple letting you know it's dissolving the brake dust and grime. Some extremely dirty wheels will require a little agitation with a soft brush and possibly some more product. I keep up with my wheels, so I usually just spray it on, let it turn purple, then hose it off. Don't let the product dry on the wheels. Wipe off the water with a microfiber cloth for the best results. Always use separate tools for your wheels and the cars body.
