Set the timer to 64 seconds

Online timer for 64 seconds

With the windscreen still misty at the edges, you have started the 64 seconds again and left the car’s heater working on the frosted glass. The second run gives the remaining haze a little longer to clear while you stay inside the vehicle. Instead of watching the display, check the mirrors and settle anything loose beside the driver’s seat.

As the windscreen warms through the second countdown, your phone may darken its screen before the time has finished. That does not necessarily stop the countdown, so there is no need to keep tapping the display with cold fingers. Leave the phone somewhere dry and stable, with the sound loud enough to hear above the fan when the final alert arrives.

While the last patches soften, use the brief wait for one small task that does not distract you from the glass. Fasten your seat belt, put your gloves away, or choose the demister setting you will keep for the first part of the journey. When the alert sounds, look across the whole windscreen rather than assuming the second run has cleared every corner.

Common questions

Why might the second countdown leave frost on the windscreen?

A colder morning, thicker frost or a heater that has only just begun warming can make the glass take longer. If any opaque or misty areas remain, continue clearing them before setting off.

What if the windscreen clears before the countdown finishes?

You can stop the countdown and use the remaining moment to check the view through the side windows and mirrors. If the glass begins misting again, keep the demister running until visibility stays clear.
