![]() One of the most common misperceptions about windshield wiper fluid is that it is essentially nothing more than glass cleaner. Many other manufacturers have employed electrically heated washer nozzles primarily to prevent them from freezing closed, not in an attempt to heat the fluid itself. Mercedes Benz has used a thermostatically controlled heating element, with the engine coolant as the heat source, since the mid-1980s on certain models. The company halted the production of these mechanisms after they found that it was prone to start engine fires. GM also claims heated washer fluid helps in removing bug splatters and other road accumulation. The system emits a fine mist of heated water that clears frost without damaging the windshield itself. For example, General Motors had begun equipping vehicles with heated washer fluid systems from the factory beginning in 2006 with the Buick Lucerne sedan. This is especially desirable in colder climates when a thin layer of ice or frost accumulates on the windshield’s surface, as it eliminates the need to manually scrape the windshield or pour warm water on the glass.Īlthough there are a few aftermarket preheat devices available, many automobile makers offer this feature factory installed on at least some of their vehicles. Washer fluid, also known as screen wash in most of Europe, can be preheated before being delivered onto the windshield. Chrysler started offering the feature in 1950 and Ford offered it in 1952. At first, it was only available as an aftermarket option that could be installed by owners (or their mechanics).īy 1946, however, General Motors was installing windshield washing machines on any vehicle they sold as an option, albeit with an extra cost attached. ![]() The first windshield cleaner apparatus was offered for automobiles in 1936. Some vehicles can also use a similar apparatus to clean the rear window or the headlights. This cleans dirt and debris off the windshield. In most vehicles, when the wiper fluid pumps are turned on, the windshield wipers are also automatically turned on. This pump utilizes jets mounted beneath the windshield or the wiper blades. Wiper fluid is typically dispersed using an electrical pump. Control within a vehicle turned on to spray washer fluid onto the windshield. Windshield wiper fluid is a cleaning solution that is sprayed directly onto the windshield of a vehicle. ![]() Is Windshield Wiper Fluid Toxic? What is Windshield Wiper Fluid?
