Why Is There Black Film on My Windshield?
Q. I have a 2010 F-150 and I have a problem keeping my interior windshield clean. Neither I nor my passengers smoke in my truck, but within a few days after washing my windshield, there is a film back on it similar to a smoke film. I’ve tried various cleaning solutions but none keep it clean any longer than a few days. This is the only vehicle I’ve owned that this happens with. Any suggestions would be appreciated.
A. This film on the inside of the windshield is from the outgassing of all the plastics and foam in your truck. I have found that there isn’t much you can do other than clean the windshield periodically. My favorite glass cleaners (approved by my wife) are ZEP Glass cleaner, Invisible Glass and Sprayway. Once the window is clean, follow up with a microfiber cloth. This should get the windows nice and clean. Leaving the windows open just a bit will help too.
