The plastic pieces that surround the door handle, window controls, and the heate seats switches are all and ugly dark peanut butter brown and I can't get it back to black. I even tried meguiars super degreaser which I used on all interior pieces that were discolored such as the steering wheel fading and the black rubber piece that surround the ignition switch (it turned greyish white) an turne it dark blak again. What to do? Or is that the correct color?

 

clean very well and paint them is what i would do.
