What the myth says about lifting wipers in snow

There’s a long-standing belief that lifting windscreen wipers before a heavy snowfall prevents them from sticking to the glass and getting damaged. The idea is simple: when the blades are left resting on the screen, a heavy layer of ice or packed snow could freeze them to the surface, bending or tearing the blades when you finally try to move them. Proponents argue that raising the blades gives you a window of time to clear the windscreen without fighting with a frozen wiper arm.

Like most practical winter tips, there’s a grain of truth here. Wipers can become stuck if ice forms between the blade and the windscreen, or if snow compacts under the blade and freezes around the mechanism. Lifting the blades is a precaution some drivers take to avoid this sticky scenario. But lifting isn’t a cure-all. It also introduces its own set of considerations—wind, mechanical strain, and the odds of losing track of them when you return to the car after a session in the cold. The key is balance and sensible practice rather than a universal rule.

What actually happens to windscreen wipers in snow and cold

How wipers are built and where they rest

Windscreen wipers rely on a combination of a metal arm and a flexible rubber blade. They’re designed to press against the glass with enough force to clear rain and light sleet, but not so much that they scratch the windscreen. When the vehicle is parked, the blades rest at the bottom of the windscreen or in a small recess along the cowl (the area beneath the windscreen). This resting position is chosen to minimize wind resistance and reduce the chance of damage while the car is parked.

In freezing conditions, two things can happen: ice can form around the blade and the edge may become embedded in ice, or snow may accumulate and harden beneath the blade. If the wiper motor is then activated, the blade can be forced to move through ice or frozen snow, which risks bending the frame or tearing the blade. This is why people talk about lifting or protecting the blades in advance. It’s a cautionary tactic rather than an absolute rule.

Common winter mistakes

• Forcing frozen blades after a snowfall: If the blade is stuck, turning on the wipers can strain the motor and damage the blade.
• Using hot water to melt ice: Sudden temperature changes can crack the glass or damage the rubber.
• Neglecting proper de-icing around the blades: Ice can build up at the blade’s resting point, making subsequent use harsher on the blade and motor.
• Leaving blades up for days in snowy, windy weather: Strong gusts can cause blades to collide with the glass or detach.

These pitfalls aren’t universal warnings, but they show why a thoughtful approach is better than a blanket rule. The best choice depends on the severity of the snowfall, the size of the storm, and how easily you can clear the windscreen without forcing the blades into ice.

Practical tips for winter driving safety and windshield care

Here’s a practical playbook you can follow this winter, tailored to winter driving safety and windshield care. Think of it as a toolkit you can pull from when storm clouds gather.

• Prepare the night before: If a heavy snowfall is forecast, park in a sheltered spot if possible; consider covering the windshield with a snow cover or large sheet to keep ice at bay. This reduces the effort needed in the morning and can protect the blades from ice build-up.
• Inspect blades before the big freeze: Look for cracks, tears, or hard rubber. If the blade doesn’t glide smoothly across the glass or leaves streaks, it’s time for a replacement. Winter weather can magnify small issues into major visibility problems.
• Don’t rush to lift without a plan: If you decide to lift the blades, do so carefully and return them to their resting position when you’re ready to drive. Leaving blades up isn’t a guaranteed safeguard against damage, and it can create distractions or hazards in strong winds or if you forget to reposition.
• De-ice safely: Use a dedicated de-icer spray around the blades and along the glass edge. If you’re using a scraper, work gradually to avoid bending the blade or scratching the glass. Avoid prying ice with metal tools that could nick the rubber.
• Start with defrost and warmth: When you start the car, switch on the heater and the defroster. Let the glass warm gradually; this softens ice and reduces pushing or pulling on the blades.
• Test gently, then sweep: After clearing the bulk of the ice, test the wipers on a clear portion of the windscreen. If the blade grates or sounds strained, stop and remove more ice before you attempt a full sweep.
• Keep the battery happy: Winter driving can strain the battery. If the car struggles to start, don’t press the wipers aggressively until the system is ready. A weak battery can cause the wiper motor to stall mid-stroke.

These steps aren’t a guarantee that nothing will go wrong, but they substantially reduce the risk of damage and improve visibility when the snow starts to pile up.

De-icing: tools and best practices

Safe de-icing techniques

The key to effective de-icing is a combination of patience and the right tools. Here’s how to handle ice on the windscreen without harming the glass or the blades:

1. Use a purpose-built de-icer spray to melt ice along the edges where blades rest. This reduces the risk of damaging the rubber.
2. Apply gradually layer by layer. Don’t soak the glass in a single fast application; this can cause thermal stress.
3. Gently remove surface snow with a brush or soft scraper before engaging the wipers. A clear path makes wiping more effective and reduces blade wear.
4. Defrost first, sweep later: Allow the glass to warm and loosen the ice so the blades can move cleanly without tearing.

Choosing the right scraper

Opt for a scraper with a comfortable grip, a sturdy edge, and a soft touch on the glass. Cheap scrapers may crack or leave micro-scratches. If the ice is stubborn, don’t force the blade—stop, reapply de-icer, and wait a moment for the ice to loosen.

Other snow- and ice-related car care tips

Battery health in cold weather

Colder temperatures reduce battery efficiency. If your car struggles to start on frosty mornings, it may be time to test the battery or replace it. A healthy battery helps ensure the wiper motor gets the power it needs, especially when the defroster runs at full blast.

Tire condition and traction

Winter tires or all-season tires with good tread make a huge difference in stopping distance and grip. Proper tires reduce the chance you’ll need to rely solely on wipers to maintain visibility during a sudden stop. Keep an eye on tread depth and consider swapping to winter tires if you regularly face snow and ice.

Antifreeze and wiper fluid

Cold weather demands proper antifreeze levels and windshield washer fluid formulated for low temperatures. Low fluid can leave you with a cloudy view even after you’ve cleared the ice. Check your manufacturer’s recommendations and top up as needed to avoid a foggy or streaky windscreen mid-journey.

When to leave your wipers up: situational guidance

Short-term snowfalls vs. prolonged blizzards

For a light dusting that you can sweep away with minimal effort, there’s little advantage to lifting the blades. A quick scrape and de-ice often suffice. In contrast, during heavy, persistent snowfall with strong winds, some drivers prefer to position the blades away from the glass to prevent ice from pinning them down. The trade-off is maintaining visibility and protecting the blades against corrosion or damage when the car is exposed to the elements for extended periods.

Parking scenarios

If you park in a windy or open area, the wipers can become damaged by wind gusts when left in the up position. In most urban or sheltered settings, returning the wipers to their resting position after clearing is a safer bet. If you decide to lift them, do so for a limited time and ensure they’re moved back before you drive away.

Home winter readiness and why it matters this winter

Winter storms aren’t just about roads; they’re about your entire home environment too. Cold snaps can push heating systems to the brink and create a ripple of issues—from frozen pipes to reliability concerns with boilers.
