I was VERY disappointed with this product. I've seen all these YouTube videos showing how great it cleans rims and tires. I used it on 4 rims/tires (3 were a bit dusty and dirty, 1 was very dirty and even a different color). The 3 that were a bit dusty got clean (no surprise) and the 1 that was very dirty didn't change much. Let's just say there is NO difference between day and night. All these people need to get money from this company to promote them as much as they do. In all videos you can see that it turns purple (decontamination). Don't go here :( I even used a foam gun and pressure washer! It was a waste of money for me. My advice. GO.
