This product hands down is the very best for wheels. Wish it was cheaper.

Excellent, very strong against the contamination... the odor is not good but works and works very well.

It definitely does the job but as mentioned before in the previous review, the smell is brutal. You must use this outside. It worked well for my wheels but was overkill for my particular application. I'll be keeping it on hand for when I get a customers car with tons of caked on brake dust. For light cleaning duties, I'd look elsewhere.

Every other Einszett product I have tried has been superlative, even their prior formulation wheel cleaner; it did a beautiful job removing brake dust, grime, and left my wheels and red brake calipers beautifully shiny. I figured this new recipe (ColourTec) might be even better. It is not. The smell is truly awful, which I could get past if I liked the result, but it took the shine off my formerly slick looking calipers and seemed way too harsh. No way would I recommend this cleaner. If the old formula (called simply Einszett Wheel Cleaner, I believe) returns, I will jump to purchase it again as it did a great job without the brutality and stink of this one. Why, Einsett, why?
