In order to wash the inside of the lights, you would need to remove the headlights and pour a serious cleaning solution inside it, and used a wine decanter cleaning brush to dry it. However, it is very hard for the plastic to get dirty inside.
Rather, do this: Wet sand the lenses with 200+ grit sand paper. After they are good and sanded, I believe you wipe them off with either metal polish or scratch-x. The product is listed in the FAQ. You can also try a convertable window cleaner first, but it won't do the job nearly as well.
