Used oil fades plastics? How to fix?

Got a brand new ’16 foreman had some oil on my hands while doing an oil change one thing that made me mad was i broke a tab on the bottom near the foot shift while removing plastics to switch out the oil filter, then i stood up and touched the atv and oil got on part it was the used oil. Touched my plastics and tried to wipe it off and the piece I touched looks faded and dull now compared to the other side that never touched oil. I have that black deluxe color. I tried cleaning with detergent soap and i tried some vinegar, din’t make a difference. Now im worried my new ’16 foreman will look dull. Whats the best way to bring back that factory shine? Worst case scenario how much are new black (deluxe) plastics for the ’16 model?
