Sanding polycarbonate for frosty effect

I did this at TechShop Menlo Park. http://www.techshop.com

These large sheets of polycarbonate are to be sanded down for a frosted effect to be used in the construction of large art light-boxes.

Step 1: Peeling

The shiny surfaced sheets are revealed by peeling the protective layer from each side.

Have you tried using solvents and potscrubbers to haze the plastic? But then I don't know what is worse, getting dusted with plastic micro particles or breathing in chemical vapors.

 A Scotchbrite Pad and a garden hose works on acrylic. Not sure if it would work on polycarbonate though.

Also, a finish sander would work better than a rotating disk sander. (No swirl marks.)
