You should strongly AVOID using back to black and other petroleum "shine" products. They deteriorate the rubberized material and will ultimately lead to severe cracking and/or fading.

The ABSOLUTE BEST product to use on the wing, and any other rubberized or vinyl surface (such as the soft interior surfaces) is Dawn dish soap and a soft brush. On foamed surfaces, like the wing, if you want it to be "darker" use a liquid dye like Rit, or use 400g sand paper and wet sand the surface.
