From the performance but I am a bit disappointed. As I had expected me much more. For one thing I had to deal with double and even then were not all debris removed all tires. In particular, on a rim was very stubborn dirt, the the cleaner had not even "dissolved".
I suppose for someone who cleans his wheels regularly, the product does very well determined his service. For stubborn dirt, it is not with "spraying - spraying - Wait" done.
