Door Panel opinions needed

Wheres the before photo!! lol That panel looks great. Im afraid mine could be smoke and arm oil mixed. Gonna find out if it will come cleaner. I moved the car into the house garage so I can paint in the shed. Lots of room the work when i get home tomorrow.

Mine were not horrible looking, but they took a bit of work.
The 'arm oil' could be tough if it actually is in the vinyl. Smoke- no problem. Between the 2 products I mentioned. Pretty much ANYTHING on the surface, and some absorbed in WILL be removed.
