If your car does not have a demisting button, you can opt for other effective solutions:

Use a commercially available defrosting spray.
Protect the windshield with an anti-frost tarp placed the day before.
Make a homemade solution (mixture of water and isopropyl alcohol) to spray on the frost.
Conclusion

With this little-known button, winter mornings no longer have to be a chore. Defrost your windshield in the blink of an eye and leave in the warmth without stress. Adopt this tip tomorrow and say goodbye to the ice scraper for good!
