Well then- I'll consider that a big compliment.
My process is vaccum with shop vac for the heavy stuff. I pre-treat everything with Johnson Wax extraction cleaner solution- mixed per the instructions on the container. I bought a yeard/garden sprayer to keep the solution in, and just pupmp it up and spray away. I hand scrub the carpets with a soft brush to avoid felting, then use the Thoro Matic extractor to get all the solution out. Depending on the car, I may use the JW solution in the extractor, or just straight hot-as-you-can-get-it water in the tank. I go over the areas a few times before moving to the next area. That's all for the carpets and seats.
I wipe everything down with Griot's interior cleaner, and then treat with Griot's vinyl/rubber dressing. I use their window cleaner also, but use a MF towel to dry the windows.
BTW- the car is a gift to his daughter for college graduation. He was very please, and she should be also.
