This approach is safer and more effective than many common shortcuts. Pouring hot water on frozen glass can cause sudden temperature changes that lead to cracks, while aggressive scraping can damage the windshield surface and waste valuable time. The defrost setting also reduces interior fogging, helping maintain clear visibility once you start driving.
For best results, keep the windshield clean, allow airflow to circulate freely, and avoid leaving the vehicle running unattended. Drivers of older cars without a dedicated defrost function can prepare ahead by using frost covers, commercial de-icing sprays, or safe homemade solutions. By taking advantage of the tools already built into your vehicle, winter mornings become simpler, quicker, and far less stressful—letting you start the day with clearer vision and less frustration.
