I picked this up from another site if it real bad and going to be thrown out it may be worth a try first.
I got sick of the faded and crazed look of the screen on the old girl and was getting close to replacing it, but decided to give a try to rejuvenating it. I figured I had nothing to lose by trying.
Step 1 was to wash the screen
Step 2 sand the whole screen with 600# wet and dry
Step 3 repeat step 2 but this time with 1200#
Step 4 buff with water rubbing compound
Step 4 buff with Meguires plastic polish
Step 5 Finish off with Vuplex
The buffing was done with a cheap lambs wool pad on my drill
