Dam the black plastic in my 08 Tl is all scratched up and dirty with dirt from our shoes.
How can i clean it up and protect it. It makes the inside of the car look so nasty.

 

Maybe be a little more careful with the shoes?

A little simple green to clean the scuffs away, and then some Aerospace 303. Good as new, unless the scratches are really deep.

 

Try Mr Clean Magic Eraser.

Test a small area first.

Seemed to work well for our 2G door sills, etc.

 

clean the area first, a 5 to 1 mixure of water to woolite is what I use and it works perfectly. After that, treat it with some 303 aerospace protectant. If you are really worried about getting it scratched, you could buy some plastic film and apply it there.
