I copied this off a site (Can't remember which one) a long time ago:

1. When wet sanding, dip the paper in clean water often. You can also re-wet the lenses during the sanding process using a spray bottle.

2. Using straight horizontal strokes, wet sand the lenses with 400 grit wet/dry sandpaper to remove all deep pitting and even out the lens surface. If you have heavy pitting or severe clouding/yellowing, start with 240 grit. It will save you a lot of time and elbow grease. This phase is complete when all of the deep scratches and pits are removed. They should be very hazy at this point but consistently hazy.


3. Follow up using the same process but graduating through 600, 800, 1000, 1500 and 2000 grit paper. Depending on availability, you can skip some of the grits but it might require more sanding with the grits that you choose. They should be looking good now...shiny when wet but very hazy when dry.

4. Using a fine rubbing compound, buff the lenses to a nice smooth finish. Buff again with plastic polish following the instructions that come with the product. Meguire's PlastX and Novus will work well to polish them to a like new appearance. Try to use a polishing product that contains a UV protective finish.



A simpler way though is a cleaner sold on Amazon.com called Plexus. I've used it and it works well.
