It does its job as it should. It removes quite a bit of dirt and with a little scrubbing it works perfectly. As for the smell that most people mention, yes, it smells like the others of its kind, nothing particularly special.

Very powerful product, does exactly what it says! Cleans every dirt of the rim. Just be careful when spraying....a mask is needed for protection from inhalation.

It does what it promises. I helped it with a brush because it had a lot of stubborn dirt. I also did all 4 wheels and used more than half the amount.
