Overview
- With Arctic air entrenched, the Met Office keeps an amber warning in place and forecasts sub-zero nights and further wintry hazards, according to chief forecaster Neil Armstrong.
- Motoring expert Ben Welham of Cinch advises slipping old socks over wing mirrors overnight to prevent icing and save time on frosty mornings.
- Green Flag and Which? warn against pouring kettle-hot water on frozen glass because rapid temperature change can crack or weaken windscreens and spilled water can re-freeze.
- Recommended options include a sealed ziplock bag filled with warm (not boiling) water glided over the screen, a rubbing-alcohol-and-water spray, commercial de-icers, and in-car demister settings.
- Experts caution against viral food hacks such as rubbing potato or onion on the windscreen, noting these can be ineffective or leave a gunky residue.
