I have some moderately severe scratches on the clear tail lights plastic cover. Probably from cleaning the snow/ice build-up this past winter.
What would be a good way to remove them? Polishers would scratch the lenses worst?
Any suggestion appreciated !

 

You can pick up plastic scratch remover / polish at most auto stores. Worth a try.

Try some of the stuff at the link MDRX8 gave you, or try some Novus (my personal favorite). If all else fails, you'll probably have to replace the lenses, but it's worth a try polishing them first.
