What type of cloth did you use to clean it?

Regular cotton t-shirt seem to put fine scratches on the plastic.

 

Foam pads to use the plastic cleaner and polish. Microfiber towels to wipe off.

Once I got mine clean, I put a piece of static cling window tint on the outside since the side windows were already tinted. The film also helped keep the outside from getting scratched and kept the wrinkles out.
