Invisible Windscreen Wiper – What Is It and How Does It Work?


While traditional wipers have been a real lifesaver for many drivers and their passengers for decades, helping them navigate through rain or snow on the road, they are far from an ideal solution. In light rain or heavy downpours, especially when accompanied by strong winds, conventional wipers may not efficiently clean the windscreen from water droplets and snow. To reduce reliance on this conventional solution, the automotive industry has introduced the concept of an invisible wiper or a glass coating, such as Glaco offered by the Japanese brand Soft99. If you are curious about how it works, read this article for more information.

What is a glass coating?

A glass coating is a specialized product applied to the surface of a windscreen to create an invisible layer based on chemical compounds, including siloxanes, PTFE, and alcohols. Its purpose is to fill the tiny pores on the glass surface, which, while invisible to the naked eye, can effectively trap water, leading to the formation of droplets. These droplets can significantly reduce visibility during rainy weather.

Furthermore, a glass coating acts as a barrier against dirt.

What are the advantages of using a glass coating?

Thanks to its water-repelling properties, a glass coating can significantly enhance visibility during rainy conditions, which is crucial for safety on the road. Additionally, products like Glaco can improve nighttime visibility as well.

Since the application of a glass coating reduces the need for windscreen wiper blades, it can lead to cost savings by decreasing the frequency of wiper blade replacements.

Another significant benefit of applying a glass coating to the windscreen is the time saved on cleaning. With less frequent cleaning required, cleaning sessions become noticeably shorter.

Soft99 also offers Glaco Mirror Coat Zero, a product designed to enhance side mirror visibility, further improving safety in adverse weather conditions.

Key considerations for glass coating selection

The effectiveness of a glass coating application depends largely on the brand of the product you choose, as well as the quality and cleanliness of the windscreen.

While price is an important factor, it is crucial to select a product from a reputable manufacturer to ensure it performs as intended. Keep in mind that it is not only the hydrophobic and oleophobic properties that matter but also the longevity and durability of the product. Higher-quality coatings are less likely to require frequent reapplication. Additionally, the ease of application should be taken into account.
