Plastic shift knob too clean...

...appears to now show the wear. Anyway to restore the black on the plastic? Cleaned with Blackfire APC @ 4:1

Blackfire APC diluted 4:1 and microfiber cloth. Quick rub on the 'ol knob.

Blackfire APC did that to my exterior trim when I tried the sample I got. I had to use Mothers heavy duty trim cleaner to fix what Blackfire APC did. The good thing is it was only the front cowl I used it on. I chucked the remaining blackfire APC into the trash. I usually like blackfire products but I did not like this one.
