There’s easier ways to get the “fog” off your headlights. Don’t pay someone $10-$15+ to do it. This is a relatively simple job. Many ways: one I did that works fine,I mixed Simple Green with a little Dawn dish soap. Neither harms the environment. Dawn is what they use a lot of to clean oil off fowl when they get in oil. Dawn is also good for crud removal. Mix them together or do separate. Apply to inside of headlight lens. Rinse, wipe gently. This can also be used to clean your motor, wont harm the sea if that’s where your runoff goes. There’s other ways also, search the web.
