I use Bilt Hamber's AutoWheel active cleaner, thats the stuff that turns purple when its done the job, probably similar to the product you mention, and yes it brings things up really well and is also gentle on the finish.

Only need to use it maybe twice a year for a deep clean because i use a high flow pressure washer and Bilt Hamber's detergent (not snowfoam) meant for pressure washer dispensers, a few minutes soak on the wheels with now and again a bit of gentle agitation and they come up spotless anyway.
