Hi, I've been doing a lot of reading about how to wash my new Model S and I think I'm comfortable with my current choice. Two bucket method, Optimum No Rinse Solution and a CG Microfiber Mitt. I've owned the car for a month and washed it once, the interior has been cleaned with microfiber towels and plain water. I'm wondering at this point if I should add a protective coat of wax and whether anyone can recommend anything to clean the seats, the dash and MCU.
