What does the routine maintenance of vehicle weatherstripping primarily involve?

Daily maintenance of automotive weatherstrips primarily involves the following steps. First, clean them using automotive detergent. After cleaning, apply a layer of highly penetrating protective agent to prevent weatherstrip aging. Additionally, gaps in the weatherstrips easily accumulate sand and dust, which can lead to corrosion. Therefore, use a brush to thoroughly remove any accumulated debris. Seals are a vital component in doors and windows, serving as a robust measure to ensure airtightness, watertightness, and sound insulation. They also provide reliable assurance for the safety of glass within doors and windows when subjected to external forces.Due to exposure to weather and sunlight, seal strips may shrink, age, or deform. Therefore, they must not operate under tension and should remain in a free state. During installation, seal strips are often stretched excessively to tightly secure the glass, compromising their free state and causing them to remain in a stretched, deformed condition. Practice has shown that installing gaskets under tension has led to issues such as detachment, tearing, and cracking. To prevent this, gaskets should be cut slightly longer than the frame dimensions during installation. At corners, they should be cut at an angle and securely bonded with adhesive, allowing sufficient expansion allowance.
