For daily cleaning, aluminum doors and windows can be cleaned with a soft cloth dampened with water or neutral detergent. Avoid using ordinary soap, laundry detergent, or strong acid and alkaline cleaners such as scouring powder or toilet cleaner to prevent corrosion. Regular maintenance techniques include avoiding bumps, cleaning and dusting, keeping away from acids and alkalis, isolating from moisture, and removing rust. At the same time, try to avoid contact between acidic and alkaline chemicals and the surface of aluminum alloy doors and windows. Regularly check the connection points of the door and window frames, tighten bolts promptly, and replace damaged parts.
Positioning pins, wind braces, floor springs, and other vulnerable parts need to be checked frequently and lubricated regularly. Sealing strips and glass sealant are key to sealing and insulation; if they fall off, they should be repaired or replaced promptly. [4] Sealing strips may dry and harden due to weathering, sun exposure, and rain, hardware accessories are prone to wear, and aluminum profiles may deform or shift; therefore, maintenance is necessary. Dust accumulation and deformation may cause difficulty in sliding; the door frame should be kept clean, especially the sliding track, and dust can be removed with a vacuum cleaner. After prolonged use, a small amount of paraffin wax or a few drops of machine oil can be applied to the sliding tracks to reduce friction and maintain smooth opening and closing.
In humid, salty coastal environments, the surfaces of doors, windows, and hardware are easily corroded, affecting their appearance and performance. Therefore, corrosion-resistant profiles such as powder-coated or fluorocarbon-coated materials can be selected to enhance protection.
