Overview
- With Met Office snow and sub‑zero warnings in force, the AA says the quickest safe method is warm air blowers plus air conditioning to clear screens.
- Drivers are cautioned not to pour hot or even lukewarm water on glass and not to smear potatoes on windscreens, which can damage or obscure visibility.
- The RAC advises applying then wiping off a thin layer of shaving foam inside the screen to leave a temporary anti‑fog film that reduces misting.
- A widely shared ‘button sequence’ echoes official guidance: heater on high, A/C on, recirculation off, and windows cracked slightly to dry cabin air.
- The AA promotes prevention such as garages, proper covers or dry cardboard and approved de‑icers, while media continue to tout household tips like lemon juice, vinegar mixes and salt sprays.
