Magnetic Window Cleaner Wiper Key benefits Clean windows, aquariums and hardtoreach glass surfaces from both sides without climbing or external access. Strong magnetic coupling keeps the two halves aligned on thicker, doublelayer, or vacuum glass so cleaning is safe and effective. Replaceable inner cleaning cotton and durable materials extend product life and reduce ongoing costs. What it does and why you need it Removes dirt, watermarks and grime from interior and exterior glass surfaces while you work from the inside. Designed for thicker or doublelayer vacuum glass where strong magnetic force is required; use the unit correctly to ensure full magnetic contact and safe operation. Includes an antifalling safety rope and wrist security thread to prevent accidental drops when cleaning exterior panes. Materials and performance Construction: quality ABS body, natural latex components, and a permanent magnet with strong magnetic force that resists demagnetization. Cleaning pad: removable and replaceable inner cotton sponge for longterm use. Durable build for repeated use on windows, shower doors, aquariums and other flat glass surfaces. Compatibility and fit Suitable for single panes as well as thicker, doublelayer or vacuuminsulated glass where strong magnetic attraction is needed. Designed to work as a squeegee and scrubber for standard residential and most commercial glass surfaces. (Refer to your glass thickness and magnetic strength requirements to confirm suitability.) How to use 1. Separate the two halves by rotating each side 90 degrees to unlock the magnetic coupling (use the antipinch separator feature). Pay attention to finger placement when opening or closing to avoid pinching. 2. Wet the cleaning sponge with water and a mild detergent. 3. Attach the outside half to the exterior pane first and secure the antifalling rope; keep the security thread looped on your wrist. 4. Place the inside half with the handle on the interior face and let the magnets engage through the glass. 5. Move the interior handle to scrub and squeegee the outside surface; the inner cotton as needed. Safety and care notes Rotate the two sides by 90 degrees when separating to engage the antipinch separator; be mindful of your fingers when closing or taking the halves apart. Always use the wrist security thread and antifalling rope when cleaning exterior windows to prevent accidental drops. Avoid using on heavily scratched or uneven glass surfaces that could impair magnetic contact. Practical use scenarios rise apartment: clean the exterior face of balcony or livingroom windows from inside, using the magnetic coupling and safety rope to avoid leaning out. Aquarium maintenance: clean both the inside and outside of aquarium glass without getting wet or reaching over the tank. Bathroom and shower doors: remove soap scum and water spots from shower glass where access to the exterior is limited.
