DEKRA: The wrong windshield washer fluid can become a safety risk
I can see!
Drivers must have a clear view in every situation. If dirt or water stains on the windshield hinder visibility, this can impair drivers’ concentration and increase the risk of accidents, warn the safety experts at DEKRA. Suitable windshield washer fluid, intact windshield wipers, and a working windshield washing system are important safety factors.
- Winter washer fluid is unsuitable in spring and summer
- Household cleaners can corrode plastic and paint
- Defective wiper blades: Major problem in German statutory inspections
“An unsuitable windshield washer fluid or just water in the washer reservoir can represent a true safety risk,” warns Kunst, the DEKRA expert. “Especially in the dark or when the sun is going down, light coming from up ahead and passing through a dirty windshield can cause glare, which impairs the driver’s vision, increasing the risk of accidents.”
Anyone who wants to be absolutely sure can rely on all-weather products with less antifreeze during the transition from cold to warm weather. These will clean well in the summer while also providing protection against frost. The DEKRA expert advises people to stay away from putting dish soap and other household cleaners in their washing fluid reservoirs. “Unsuitable cleaning or washing fluids can cause paints or plastics to blister, dissolve material, and cause stress cracks in headlamps that are made of polycarbonates.”
“Fogging” and “magic dust” are names for another effect that can significantly hinder a driver’s vision. If the inside of the windshield is not cleaned regularly, matte films of debris consisting of dirt, cigarette smoke, or vaporized plastic can often form unbeknownst to the driver. These also reduce transparency and can easily cause undesired light dispersion on the windshield.
