Like I said - sometimes there are some stains on the backside of your headlight glass. This video gives you a idea how easy to clean them. You can do the process with steel wool or with second magnet wrapped inside cotton tissue.
I would add a piece of microfiber rag between the headlight and the magnet to prevent any scratching assuming the outside of the headlight has been washed before that.
Lol...that was cold...😆 He tried though at least and I guess if it's not that bad inside, it would work but the inside of my headlight would rip the cotton off that wool and violate it and the thread would come back with nothing on it except a note saying "help" lol...
@@greathey1234 Acetone will melt a layer of the plastic inner surface.. + the fumes may affect other plastics inside. Will it remove debris, marks etc? You need to try it & let us know
