So, things to try, Plexus, olive oil, toothpaste, Magic Eraser, Deep Woods Off!! Lots of suggestions! The neighbours are going to think I've gone crazy!!
They very likely used a "Window Marker", they are made for drawing decorations on glass windows
. Easy to find at the stores. They do come in the color white as well as other colors. Here is a link for how to remove that stuff. http://www.crayola.com/faq/stain-rem...as-or-mirrors/
Don't use the Magic Eraser, it is too abrasive and can scratch the plexi. I use a Magic Eraser to remove heavy oxidation on fiberglass but if you rub too hard it will sand through a gel coat.
If after trying the recommended cleaning procedure you still have a problem....
Go to your local auto parts store and pick up one of the kits made for cleaning up plastic head light
and tail light
covers. It should do the trick without doing any harm and the leftover product will be useful for polishing up your tail lights
so they shine brightly. Always good to get further use out of something you buy rather than just a one time deal where you don't use it all up.
