Re: How do I clean very hazy instrument lens plastic?

Mine looked similar to that. I had a small amount of a 3M headlight restoration kit left after I used it, so I figured it wouldnt hurt to try that out.

It didnt remove it all, but it is 100x better. You could do the same with some regular sandpaper and plastic polish. If I remember right the 3M kit goes 500, 800, 1000, 3000 wet then polish. The damage is all the way through the lens, but by doing a sand and polish on both sides it will make the gagues much more visible.
