Aluminum frames require minimal maintenance, but we recommend:

  • Clean regularly with mild soap and water
  • Avoid abrasive cleaners or tools
  • Inspect seals and moving parts annually
  • Lubricate hinges and tracks as needed
  • Check for debris in drainage channels

For powder-coated frames, avoid harsh chemicals that may damage the finish. Anodized frames may benefit from occasional waxing to maintain luster.
