First find out if they are made of acrylic or polycarbonate , acrylic can be buff starting with 1000 sandpaper then 2000 and a good compound to finish(depending how bad they are) Do not try on polycarbonate.
If the answer to Steve's question is yes, 3M makes an awesome headlight lens cover restorer. You can also contact Bowmar at 1-800-628-5188 and ask for technical assistance. They have an excellent customer service department. MT
I used the cleaner that is recommended for glass cook tops. I think its something like ceramabrite but don't think I spelled it correctly. Regardless it worked like a charm!
