Used it for the first time yesterday, as mentioned above it seems to clean well, i mixed it approx 1-3 as my wheels never really get that bad as i clean the car most weekends and thought that would be strong enough, it seems to leave the wheels with quite a nice shine even before wax etc once dried, the undiluted liquid smells putrid!

But once it's mixed and sprayed out it's lovely!

I'd recommend the megs spray bottle and chemical resistant head, works a treat and it's adjustable.

hope this helps.
