• Cleaning the Tracks: Use a vacuum accessory to remove grit and debris from the bottom tracks of sliding windows and doors frames. This avoids damage to the rollers and seals.
• Gasket Care: Wipe down rubber seals with a moist fabric. Prevent extreme chemicals that can trigger the rubber to die or become breakable.

• Tightening up Hardware: Periodically check the screws on handles and hinges. If they are loose, tighten them gently to prevent unneeded vibration and wear.
