Comments.Text: peanut butter and toothpaste. rub them onto the windshield, and then wipe of and wash with water and soap. (the soap doesnt really matter, it will just get the smell off) that solution works for most scratches, i think it works for plastic. ;)

  Haven't tried this with Lego, but here are the first two things that come to mind.

  About the transparency, I would try the standard headlight cleaning solutions for a car.

  You've got three different approaches: 1) products that fill the scratch, 2) products that essentially dissolve the plastic material so that it re-hardens smooth, 3) products that help you polish the scratch away.
  
  1. A silicon-based lens cleaner can do this and works for small scratches or some "cloudiness", but it won't be perfect. For example [Bausch & Lomb](http://www.northernsafety.com/Product/4190/Bausch-Lomb-Sight-Savers-Large-Disposable-Lens-Cleaning-Station-with-Silicone-Spray) or [a furniture polish with wax](http://www.ehow.com/video_4791118_remove-scratches-plastic.html).
  2. It is likely that the Novus and similar products fall into this category, but they rely on polishing for the finish... similar to CD or DVD repair.
  3. Here is [a step-by-step method](http://www.ehow.com/how_5013183_remove-scratches-polycarbonate-lenses.html) using household toothpaste.
