How to use the online timer
With the windscreen heater running, leave the countdown to cover two minutes and fifty-four seconds while you clear light frost from the side windows and mirrors. That gives the warm air time to reach the glass without making you stand over the display. Keep the keys with you and stay beside the car as you work.
Frost thickness, outside temperature and the car’s heating system can all affect how quickly the windscreen clears. The duration can be changed directly on the page if the first patch of clear glass appears sooner than expected or the centre remains opaque. Adjusting it makes more sense than waiting through an interval that no longer matches the conditions.
While the glass warms, brush loose frost from the lights, check the mirrors and clear any ice around the wiper blades. These small jobs fill the interval without drawing attention back to the changing numbers. Before setting off, return to the windscreen and make sure the view is clear rather than relying on one thawed patch.
Common questions
Will the set interval be long enough after a heavier UK frost?
It may need extending when the frost is thick, the temperature is especially low or the heater starts from cold. Add a little time and continue clearing the other windows while the warm air works.
What if the windscreen clears before the set interval ends?
Stop the countdown once the whole viewing area is clear and the wipers can move freely. There is no need to wait out the remaining time when the glass is ready.
