A frozen windscreen is the most predictable British winter problem there is, and every year it still catches people out — scraping with a bank card, pouring a kettle of hot water over the glass (a good way to crack it), or driving off with a letterbox-sized hole cleared in the frost. None of that is necessary. A small, cheap kit kept in the car turns a freezing, late-for-work morning into a two-minute job.
These picks cover the whole cold-morning routine and the problems that ride in behind it. A can of de-icer spray and a proper scraper clear the glass fast without damaging it; a magnetic frost cover fitted the night before means there's often nothing to scrape at all; winter screenwash stops the washer jets and reservoir freezing and clears road grime and salt on the move. We've then added the two things a frosty morning most often turns into: a slip on an icy driveway, and a car that won't start after a cold night — so a pair of ice grips and a compact jump starter round out a genuinely winter-ready car.
