If you've got at least $10 and an hour, it is easy. Your local auto parts store has several Headlight Restoration Kits. Essentially, the clear coat on the plastic or acrylic headlight begins to break down after years of use. That is when oxidation and wear begins to set in. The kits polish or sand away this top layer to reveal a fresh clean layer underneath. The key is to ensure you get a kit with a protective coating to put on top of the freshly polished headlights. Yellowed, dull, or fogged headlights are a safety risk, so when you have a chance, get them clean!

**NOTE: The plastic on the headlight is usually part of a housing and can't be removed individually, but the entire housing can if it needs to be replaced.**

Using Deep Woods Off, which is an insect repellent, to clean a headlight lens is not recommended. While it may temporarily remove some grime, the chemicals can potentially damage the plastic lens and affect its clarity over time. It's better to use a dedicated headlight cleaner or a mixture of soap and water for safe and effective cleaning.
The answer to how to clean your headlight lens depends on how dirty your lens is. If it just has bug juice and road grime any good car soap will clean it, just be carefull not to scratch the plastic. However if your lens is really yellowed or the clear coat cracked then you will need kit designed to clean the lens.

On my 2001 Jetta 1.8T, the outside of the plastic headlight housing gets yellow, probably due to UV light. I use Mother's Mag & Aluminum Polish, which removes the very thin layer of plastic (probably less than 0.001") that has yellowed.
