Before I bought this I used 409 and a rag to clean my wheels. It worked just as well as this. Clearly I need to buy a wheel brush to use along with any cleaner. When you think about it any cleaner that could REALLY remove all that brake dust and road grime would probably be unsafe to be spraying around and rinsing into the gutter. Think I'll use up this bottle (with a wheel brush) and go back to 409 or the car wash bucket. Nothing worth doing is ever easy.
