‘Magic’ button defrosts car windshield in seconds
Winter Driving Made Easier
Winter mornings can be frustrating with frozen windshields and
stiff fingers, but most cars have a feature designed to help: the windshield defrost.
How It Works
Pressing the defrost button directs warm, dry air onto the glass.
Heat loosens ice, while dry air reduces moisture, clearing frost
and preventing fog. It’s safer and faster than pouring hot water
or aggressive scraping, which can crack or scratch the glass.
Maximizing Effectiveness
Keep windows clean, reduce interior humidity, and avoid leaving
the engine running unattended. For older cars without defrost settings,
frost covers or de-icing sprays help prevent morning delays.
A Calmer Start
Using the defrost properly “restores visibility without force or risk”
and can turn a stressful winter departure into a smoother, safer start to the day.
