I use Chemical Guys total interior cleaner & protectant. Spray it on a microfiber towel, make a couple passes, and buff off excess with clean microfiber. Makes it glossy and looks deep. Plus keeps it protected.
If you would like to restores the plastic's appearance use a very light polish and then buff lightly with a microfiber towel. I used a motorcycle face shield plastic polish/restorer and it got all that fake wood plastic shining as if it was new. You want to find the most least abrasive polish you can and then only use MF towels.
My passenger side wood trim - right along the top of the glove box - has few cracks in the varnish (or plastic, whatever it is) from when I removed it to fit an aftermarket radio. I was also thinking to maybe polish it down and recoat it... but other than that, it keeps clean well enough with a damp cloth.
I'm not familiar with the various models and trims and whether they have real wood or not. But it should be quite easy to determine if it's plastic or wood. If it's plastic I would not be putting any sandpaper to it. As I stated earlier... a very fine plastic polish will remove all the spiderwebbing and other fine scratches and make it look like new. I actually get compliments on how shiny and new mine looks.
