Glass wipers, also known as window squeegees, are cleaning tools designed to effectively clean and dry glass surfaces. They typically consist of a handle and a blade made of rubber or silicone. The blade is designed to fit closely to the glass surface, allowing it to remove water and cleaning solutions without leaving streaks or spots. Glass wipers may also have a removable blade for easy cleaning and replacement, and some models may have adjustable handles for extended reach or a pivoting head for cleaning at different angles.
