Bleche White ruins the tires. I have a big bottle that I used on someone else's tires once, and now I don't know what to do with it. It's bad and it turns the tires gray fast. Any tire cleaner with bleach is bad, unless it has whitewalls. But considering all the white walled tires we see, I have to say stay away from Bleche White. It's the NicSand MF of tire cleaners.
