I live in California and my Honda Civic gets a build up of gunk on the inside windshield, had to remove and hard to see, remedies please?
Hello, thank you for writing in. The first thing you can do is use a window cleaner that creates a "water-proofing" effect. These are typically used on the outside of the window to make the rain bead up and run off smoother. You can use is sparingly inside to make the window easier to clean. The only way to truly solve the issue is to find out what the "gunk" really is. If someone in the car smokes cigarettes or E-Cigs, this would definitely leave a strange film that clings heavily to the interior. Other contenders may be air fresheners or anything that is sprayed inside, exhaust fumes (which are dangerous to your health, and means you have an exhaust leak), or something coming from outside of the vehicle from the environment around you. If that is the case, upgrade and change your air filters (both the engine air filter and the cabin air filter) for a short term fix. Good luck.
