Online timer for 115 seconds
You have started a second 115 seconds while the car’s heater continues clearing overnight frost from the windscreen. The first interval may have softened the icy film without opening a clear view, so this repeat gives the warm air more time to reach the glass. While it runs, you can watch the remaining opaque patches rather than scraping at glass that is still firmly frozen.
Repeating the same countdown keeps each warming period consistent when one interval is not enough. After this second run, compare the cleared area with what you saw after the first: a thinner frost layer may release, while a hard freeze can need another measured spell. If visibility becomes fully clear before the signal, the repeated interval has already served its purpose and there is no need to wait beside the car.
With the engine fan, passing traffic and doors closing on a cold UK morning, the ending signal may be difficult to hear from outside the car. Keep the phone somewhere dry and visible, with vibration enabled if available, so the screen or movement can mark the finish too. If you miss the sound, check the windscreen itself before starting another round; the changing frost is a more useful guide than an unheard alert.
Common questions
Could the second interval be too long for light frost on a UK morning?
Yes. A thin coating may clear before the interval finishes, especially when the air temperature is only just below freezing. Stop using the countdown as your guide once the whole windscreen is visibly clear.
What if the windscreen is still frosted when this interval ends?
A harder overnight freeze or thicker ice can need more warming time. Check whether the cleared area has expanded, then use another equal interval if the glass still blocks your view.
