What do you recommend for black (unpainted) plastic that faded in the sun?

In reply to californiamilleghia :
Not certain if wide Sharpie uses exactly the same composition as regular. For acrylic ("Perspex", "Lucite", other names for PMMA) don't use alcohols which can craze crack the plastic. I do use isopropyl on non-plastic items for Sharpie marks with good success.
Polycarbonate such as "Lexan" can be cleaned with Joy, Palmolive, or Top Job according to one reference. That one also says you can use the extremely smelly butyl cellosolve for graffiti and paint removal, but I'd try it on a test piece or the always desirable inconspicuous area first. And don't use it on the acrylic either.
Coroplast seems to be a polypropylene sheet trademark, and PP is pretty resistant to all of those cleaners. "Inconspicuous area" time again.
