Gather all necessary materials: ice scraper, de-icing solution, and a microfiber cloth.
Ensure the vehicle is in a well-ventilated area.

2. Apply a Protective Coating

Sub-steps:
1. Clean the windshield thoroughly with glass cleaner and a microfiber cloth.
2. Apply a silicone-based water repellent product designed for automotive glass to the exterior of the windshield.
3. Follow the manufacturer's instructions for application and drying time.

3. Use a Windshield Cover

Sub-steps:
1. Purchase a windshield cover made for winter use.
2. Place the cover over the windshield each night, securing it to prevent wind displacement.
3. Remove the cover in the morning and store it properly.

4. Optimize Parking Location

Sub-steps:
1. If possible, park the vehicle in a garage or under a carport to shield it from frost.
2. In the absence of a garage, consider parking the vehicle facing east to catch morning sun exposure.

5. Use Anti-Freeze Washer Fluid
