Ozone generator? That sounds like NASA designed it or soemthing haha. I remember trying to clean my 91 LS after 3 student drivers grew up on this as their "1st car" so I had melted lipstick on the carpet, spilled food/drink, I even had what I was told was a spilled "protein shake" that once dried caused the rear carpet area to become cemented to the metal below it. I solved mine with this trusty "bissel steam cleaner for pets" and after a bottle of solution and an hour I could eat dinner off my floorboards.
I also hear orange pumice hand cleaner + vacuum can do wonders for carpets that are abused.
