I No Doubt it worked as advertised, But I'm just to cheep.
I tried several Spray on, rinse off products, They all worked but I would find all to fast the bottle was empty and I was left wondering what kind of harsh chemicals I had just used and rinsed away with water wondering where it will turn up next. I also worry about what will spray off my wheels onto my car while driving after I use stuff like that.
I then took the time to WAX my wheels. Ever since them I just use standard car wash soap and the end of the car wash and a microfiber towel. I have yet to rub anything, I just need to wipe away the dirt. Splash some water from the end of my rinse bucket on them and they look really good. If I have the time I will dry them and give them a shot of Turtle wax Ice spray detailer to make the next clean up even easier. Oh, and I only wash the rears ever 4th wash or so because they seem to stay clean, I'm sure this will change in the winter.
