1. Effective Double-sided Magnetic Cleaning Tool: With its double-sided magnetic design, this glass cleaning tool can reduce the risk of distortion. It performs better than previous ordinary glass cleaning tools, cleans more quickly, and is a good companion for glass cleaning. 2. Quality Features: It offers double-sided magnetic glass cleaning, with a built - in water storage sponge so there's no need to refill water. There is a 2m long safety cord to prevent accidental unwinding. The white cotton cloth can be freely removed (turn the buckle 90 degrees to remove it), and the white scraping strip made of natural latex makes it easy to scrape off excess water on the window after cleaning. 3. Triangular Design: This double - sided magnetic glass cleaner uses a labor - saving triangular design to ensure comprehensive cleaning. Triangular friction is better than four - corner friction, which can clean any dead corners more effectively, so there's no need to worry about not reaching the corners. 4. Suitable Glass Thickness: The double - sided magnetic glass cleaning tool is suitable for cleaning double - sided glass with a thickness of 15 - 24mm. Make sure that the total glass thickness (2 layers of glass + vacuum) does not exceed 24mm to avoid the glass being broken by the strong magnetic force. 5. Safety Precautions: Due to the strong magnetic force, if not used carefully, it's easy to pinch fingers, so safety must be paid attention to when using it. When using it on multi - story glass, a rope should be held in hand and attached to the outer glass to prevent it from falling and hurting others.
