Whenever I clean the inside of my car, I always am left with this film on the inside of my window. If I am driving into the sun, this is a problem, it gets kind of hard to see. I don’t know if it is cleaning product im using on the windows (windex) or if it because i armor all my interior and then the sun bakes it and it evaporates onto my windshield. Does anyone know what the problem is and a possible solution?
