Do you use an ice-scrapper to defrost your windshield? Or do you prefer throwing hot water? If you answered yes, you’re not alone.
Many car owners have to deal with the frosty car windshields during chilly winters. But wrong defrosting methods can lead to significant damages and scratches on your windshield.
Here are some ways to de-ice your windshields the right way!
1. Avoid Water Shortcuts
An icy windshield can be frustrating when you need to leave, but do not pour hot or lukewarm water over frozen glass. The AA warns that sudden temperature changes can crack the windshield and that added water can refreeze. Use the vehicle’s defroster and appropriate de-icing tools instead. If the glass is already damaged, consult an auto glass specialist.
2. Use Suitable Winter Washer Fluid
Before freezing weather arrives, fill the windshield-washer reservoir with winter-grade washer fluid rated for the expected temperatures and compatible with your vehicle’s owner’s manual. NHTSA recommends a winter fluid with de-icer. Follow the product’s mixing directions, if dilution is required. Clear ice from the glass and free frozen wiper blades before operating the wipers.
3. Use Your Vehicle’s Defroster
Follow your owner’s manual to switch on the front defroster and any heated-windshield feature your vehicle has. Give the system time to loosen the ice; clearing is not instantaneous. Keep the wipers off while they are frozen to the glass. Never run the engine in an enclosed garage, and keep the exhaust outlet clear of snow. Wait until all windows and mirrors are clear before driving.
4. Use an Automotive De-Icer
Choose a commercial de-icer labeled for automotive windshield glass, and follow its directions and your vehicle’s owner’s manual. AAA recommends commercial de-icer as an option for loosening ice. Once the ice softens, gently remove it with a suitable scraper where your owner’s manual permits. Never force frozen wipers loose. If your windshield has sustained damage, contact Auto Glass in San Antonio for an inspection.
5. Prevent Your Windshields from Frosting
To reduce frost buildup overnight, here are some ways to prevent icing on your windshields:
- Cover your windscreens with cardboard(s) overnight;
- Park in a garage or covered carport when available;
- Wrap your side mirrors with plastic bags;
- Spread a clean, dry towel on your windscreen.
Following these prevention tips will save you from significant efforts and hassles of de-icing.
