No, I didn't buy the cleaner from them. The only time I clean the inside (or the outside, for that matter) of my Jeep is when it gets too much mud and dirt accumulation from offroading. I just hose it down on the inside. I did manage to screw up my radio and my turn signals that way. I don't understand why the interior of Jeeps, especially the dashboard, isn't waterproof in the first place. That would make them really easy to clean with a water hose.
