“Invisible wipers” significantly improve visibility in the rain: after spraying it onto glass, a long-term nanosurface is formed, which provides an escape of water drops. It also prevents the glass from sticking residuals of insects or dust onto it. “Invisible wipers” facilitate the operation of wipers - they slip through the glass surface easier and therefore less wear and tear.
Spray liquid on a clean surface. Softly polish it with clean and dry tissue.
