Rim Magic by Shinybike is billed as a “safe and effective chrome or polished wheel cleaner”. It’s similar to other automotive wheel cleaners; after you spray it on, a foam appears which is designed to clean the grime and brake dust from wheels.
The directions say to let it sit for a few minutes and that you can also use a brush or sponge to remove the tough stains.
Although Rim Magic works pretty well, it doesn’t seem to work any better than other wheel cleaning products I’ve used in the past.
I’m still waiting for some magic potion that when sprayed on a wheel will remove all of the stains with little or no manual effort. Rim Magic does carry a “100% money back guarantee” though, and you can’t beat that.
Here’s a photo of some grime around the valve stem prior to the application of Rim Magic.
Here’s the same valve stem area after 2 applications of Rim Magic and some rubbing with a sponge. You can see there are still some pretty tough stains around the valve; Rim Magic removed most, but not all of the staining.
