How to Make Blurry Car Glass Clear Again?
2 Answers
Here are methods to restore clarity to blurry car glass: 1. Apply anti-fog spray: When using a defogger, simply spray it evenly on the glass surface and wipe clean with a dry towel. This leaves a protective film that alters water molecules' surface tension, causing fog droplets to coalesce into larger beads that don't obstruct vision. This method also works for other car glass, especially side mirrors. 2. DIY detergent defogger: Mix dish soap and water in a 1:6 ratio, spray and wipe before driving. The effect matches commercial defoggers though with slightly shorter duration. Alternatives like soapy water, hand soap, or laundry detergent are less effective than dish soap.
I've experienced blurry car windows many times, usually due to dust and oil stains on the outside, or water marks left after rain. When cleaning, I first wipe with a clean, damp soft cloth. If that doesn't work well, I spray specialized car glass cleaner and then wipe dry with a clean microfiber cloth - avoid using regular paper towels as they can make it worse. Worn-out wiper blades that don't clear water properly can also worsen the blurriness; check the wiper rubber and replace it if worn. As for interior fogging, it's mostly caused by temperature differences creating condensation - turning on the AC with external circulation and defrost mode clears it quickly. Regular maintenance like periodic car washes or using a sunshade when parked to prevent dust buildup can significantly improve visibility. Don't delay these simple measures as they affect driving safety.
