It's actually one of the few things I've been so amazed with on QVC (or one of those shopping channels) that I bought it. I use Proshine Tyre Trim and Shine. I'm not sure where you can buy it on it's own but you usually buy it in a pack with other ProShine products which now I'm on the subject Proshine Spray and Clean is simply amazing stuff. Spray on to a dirty car - use a microfibre cloth to wipe it off then polish with another microfibre cloth - it's one of those thing that you've actually got to use to it to believe it - it doesn't scratch your car and you don't need to use any water. Sorry, slightly off-subject there! Try this link:
