Rain-X® first becomes commercially available in 1972. In 1981, Howard Ohlhausen relocates the family business to Scottsdale, Arizona where he and his three sons continued to commit their lives to building the new family business and the Rain-X® brand.

Chicago, Illinois Ohlhausen of Unelko Corporation in Chicago, Illinois as a method for rendering nonporous surfaces water, soil and stain repellent. Following his acclaimed invention in 1971, Ohlhausen began to develop and market several innovative products.

You can even make homemade windshield water repellent by mixing a simple solution of half a cup of rubbing alcohol and a cup of water into a spray bottle. This solution will become warm, so wait until it cools to use it.

While touring the city of New York in a trolley car on a snowy day in the early 1900s, Mary Anderson conceived her idea of a windshield wiper blade that could be operated from the inside by the trolley driver.

How does it work? Rain-X Rain Repellent penetrates and seals the microscopic pores of the glass with a super-slick invisible barrier that helps to repel rain, sleet and snow on contact. The hydrophobic formula works with the natural airflow over the car to disperse rain-drops from the windscreen.

The rain repellent is a hydrophobic coating technology that forms a chemical bond and causes the raindrops to bead up and blow away from the windshield. This new innovative technology is designed especially for plastic Acrylic and Lexan windshields, and has no alcohol which can harm plastic.

Rain Sensing Windscreen Wipers / Autowipers Autowipers uses a rain sensor located in the area around the interior mirror. The rain sensor monitors the amount of moisture on the windshield and automatically turns the wipers on.

And a rain sensor the basic idea is that when it gets wet it has discs inside that expand. And when the discs expand it opens the circuit on the controller thus giving you your sensor off message.
