When I first got my car I had an issue trying to keep the film off of the inside of the windshield. Even with Windex it would leave streaks. I found out that old newspaper worked best. I then read where others were just using a damp cloth to clean their dash and not any interior protectant. Ever since I quit using any type of interior dash protectant I have not had any further issues with this film. A couple of weekends ago I noticed that the dash part closest to the windshield looked like it was beginning to discolor ever so slightly. I grabbed a bottle of the ArmorAll interior spray, wet a rag and applied a thin film to this part of the dash and then the rest of the dash. After the first day of sitting in the hot sun in an asphalt parking lot at work I again have a film on the windshield. Does anyone know of a good dash protector that will not give off an oily film but will help with the dash fading ?
