Went to Tire Kingdom to ask them about my headlights. They told me that they are too foggy and need to be cleaned. I asked them if the covers just need to be replaced or what but they told me they just needed to be cleaned with a "chemical" they have. I asked autozone and they said they don't carry that acid. Tire Kingdom wanted to charge me 50 bucks to clean em so that certainly wasn't going to happen. Is there any way i can get ahold of this mysterious cleaning product and do it myself? Would normal ammonia or some acid wash work?
