How to use the online timer
Stay beside the car while the demister works on a frosted windscreen, watching for clear patches rather than leaving the vehicle unattended. Ninety-six seconds gives you a brief window to check the glass, brush loose frost from the outside and keep an eye on areas around the wipers and mirrors. A cold, damp British morning may leave some sections clearer than others.
As the windscreen begins to clear, the remaining time shows whether the chosen interval suits the frost in front of you. The duration can be changed directly on the page if a thin coating disappears early or a harder layer remains. Adjusting it to what you can see keeps the countdown tied to this particular morning, while you remain close enough to notice changes across the glass.
With cold hands and your attention on the windscreen, a phone is usually easier to keep within sight beside the car than a laptop. Place it somewhere dry and stable, with the display visible but away from the work area. A laptop may suit a garage or driveway setup where it can remain sheltered, though carrying it outside adds distraction when you need to watch the glass.
Common questions
What could make this interval too short for clearing frost from the windscreen?
A thicker frozen layer, shaded parking or a particularly cold UK morning can mean the glass needs longer. Keep watching the windscreen and extend the duration on the page if opaque or icy areas remain.
What should I do if the windscreen clears before the set interval ends?
Stop the countdown and inspect the whole windscreen, including the edges and the area around the wipers. If visibility is clear across the glass, there is no reason to wait for the remaining time.
