I was initially very skeptical as well until I have the means sprayed. As some have said, you have to use quite a lot to be nice to cover the rims evenly and completely. Did it leave on for half an hour and then not rinsed off with a pressure washer, but quite simply with the water hose. And indeed, has any dirt, especially the places yellowed by the salt in winter, detached ... merely something to wipe with a sponge and lo and behold, the rims are like again "new". Do I buy now again, if the rims are so hard to come clean without remedies)
