Believe it or not . Toothpaste works too. My lights had a film on the inside. I removed lense, cleaned inside of lense and the silver part of headlight housing....I used a watered down solution of windex, and lint free paper towels.. You need to rub it lightly so the silver backing wont come off. I resealed the lense with high temp gasket sealer.
