Hey guys I have old mud stains that I havent been able to get out of my plastic trim on my doors and dash. Like right below the window and drive dash etc, and no matter how hard or what i use to scrub, the mud stains wont come out. Any ideas how I could get it clean? thanks

 

On something like that use some gool ol' fashioned 409 APC with an old tooth brush. Won't hurt the plastic at all, just try not to hit any leather with it (if you have leather)
