Tip for removing oxidation from plastic headlamp covers:

1. Wetsand with 400 grit using a circular pad for a few minutes. Depending on the amount and thickness of the oxidation layer, this might take a while.
2. Wetsand with 1000 grit same as above
3. Wetsand with 2000 grit same as above
For all three steps above, let the sandpaper do the work and keep it wet with a spray bottle.
4. Polish with a commercially available lens cleaner paste.

For the giant lenses on my E320 which were quite yellowed and actually crusty, this procedure worked well. I was ready to buy new lenses after trying some of the polish compounds alone. The wetsanding was necessary and sped the process.
