Don't forget about weather stripping!
I don't know about you guys and gals, but when I clean the interior and use vinyl/leather conditioner, I always go over weather stripping around the doors top and bottom. It's important because that is one of the first things to go as your car ages. It tends to dry rot so add life to it by using what you use on your dash and vinyl accessories and do your weather stripping. It only takes a couple of minutes, but can add years to it so you won't get water leaks or unwanted new wind noises coming in to your interior.
