UK drivers are being advised by the RAC to refrain from using their windscreen wipers to clear ice from their vehicles this winter. The motoring organisation highlighted that attempting to dislodge frozen ice with wipers can lead to costly damage, not only to the wiper blades but potentially to the windscreen itself.
When temperatures drop below freezing, wiper blades can become stuck to the glass, or the rubber can stiffen and become brittle. Activating them in this state can tear the rubber, rendering the wipers ineffective. Furthermore, the motor mechanism that powers the wipers can be strained or even burn out if forced to operate against a layer of ice, leading to an expensive repair bill.
Beyond the damage to the wiper system, there is also a significant risk to the windscreen. Using stiff, frozen blades to scrape ice can scratch the glass, impairing visibility and potentially leading to a need for professional repair or replacement. In extreme cases, applying pressure to a frozen windscreen could even cause it to crack, especially if there are existing minor chips or imperfections.
The RAC recommends safer and more effective methods for clearing icy windscreens. Drivers should use a dedicated de-icer spray, which works by dissolving the ice, or carefully pour lukewarm (not hot) water over the glass. Once the ice has softened, a plastic scraper can be used to remove the slush, ensuring the windscreen is completely clear before setting off.
Ensuring full visibility through the windscreen, rear window, and side windows is a legal requirement and paramount for road safety, particularly during challenging winter conditions. Drivers are also reminded to clear all snow and ice from their vehicle's lights and roof before starting their journey to prevent hazards for themselves and other road users.
