GENERAL DOOR CARE AND HANDLING

Cleaning Frequency

  • Clean doors at least every three months.
  • If within 3 miles of saltwater, clean monthly or more often due to corrosion risk.

Cleaning Wood Surfaces

  • Treat like high-quality furniture—avoid abrasives.
  • Use a clean, damp cloth to remove dust, dirt, and debris.
  • Regular cleaning prevents scratches and dullness.

Cleaning Clad Surfaces

  • Use mild detergent and water for washing.
  • Rinse with clear water and dry with a soft cloth.
  • Regular maintenance protects against weathering and dirt buildup.

Cleaning Glass

  • Use mild cleaning solutions only.
  • Wipe off excess cleaner from gaskets, sealants, frames, and finishes.
  • Avoid cleaning in direct sunlight.
  • Never use scrapers or razor blades to prevent scratches.

Cleaning Door Handle Sets

  • Regular finishes: Use water and a soft cloth; avoid abrasives, cleaners, or steel wool.
  • Oil-rubbed brass/bronze: Clean only when necessary, rinse with water, and avoid excessive rubbing to preserve patina.
  • Stainless steel: Use water and mild detergent, rinse thoroughly, and remove stains with a stainless steel cleaner if needed.

Cleaning Retractable Screens

  • Keep head and sill channels free of dust, pet hair, and debris for smooth movement.
  • Use a soft cloth or low suction vacuum (with soft brush) to clean channels when retracted.
  • In dusty/coastal areas, clean more frequently.
  • Lightly dust the screen mesh and use a gentle vacuum (soft brush attachment) when extended.

Maintaining Wood Surfaces

  • Dry water immediately from wood surfaces, especially door/window edges.
  • Inspect wood every six months, ensuring topcoats are intact (no cracks/scratches).
  • Any gaps in the finish can cause moisture damage (cracks, splits, warping).
  • If needed, lightly sand (280-grit), clean, and reapply topcoat/paint.

How to Clean the Door Track

Keeping the track clean and free of dirt, debris, and pet hair is important for smooth operation of your bi-fold door. To clean the track of your door, use a damp cloth with mild detergent, then wipe dry.

How to Clean the Weep System in Raised Sills

Keeping the drainage holes (weep system) in the elevated sill clean is essential to ensure proper water flow and prevent accumulation or leaks during heavy rain. Use a pipe cleaner, small bottle brush, or compressed air with a narrow tube attachment to clear debris from the tubes and expel it through the front holes. 

See this video guide “How to Free Debris from Weep Holes.”

Don't Neglect the Hardware in Your Door Maintenance Routine

Routine Maintenance

  • Inspect hardware every six months; increase frequency in coastal/industrial areas.
  • Check screws for tightness, using low torque to avoid stripping.
  • Inspect for wear and replace damaged parts as needed.

Cleaning & Corrosion Prevention

  • Wash with mild detergent and warm water, rinse with cold water, and dry thoroughly.
  • Coastal areas: Stainless steel may still show surface corrosion despite regular cleaning.
  • Clean hardware when washing doors/windows:
    • Coastal/industrial areas: Monthly cleaning recommended.
    • Less corrosive areas: Clean every three months.

Corrosion Protection (Coastal Areas)

  • Apply a light coat of corrosion preventatives (e.g., Boeshield T-9, CRC Marine 66, Inox®).
  • Wipe off excess with a dry cloth.
  • Avoid contact with wood or absorbent surfaces to prevent staining.
  • Follow manufacturer guidelines carefully.

How to Maintain and Adjust Hangers and Pivots

All hangers are fitted with lubricated ball bearings or plain bearings, requiring no greasing. If the doors ‘settle’ and door clearance is reduced causing friction, raise the door by the hanger adjustment nuts.

View our “How to adjust” videos here to learn the steps to properly adjust your door.

How to Clean Your Door Rollers

All sill guide tracks and header channels must be free from obstruction and excessive dirt and water. Clean visible surfaces using a damp cloth and mild detergent, then wipe dry. All rollers are fitted with sealed precision bearings requiring no maintenance, but clean exterior surfaces and protect as recommended above.

How to Clean Bi-Fold Hinges

Clean visible surfaces using a damp cloth and mild detergent, then wipe dry.

Surface Mounted Locking Mechanisms

We recommend applying WD40 to the sliding pin within the drop bolt and to the lock cylinder (if present). Access holes or slots are available on all drop bolts, located at the top and bottom of door panels, facilitating this task without removing the locks from the doors. Any surplus lubricant should be wiped away. Clean visible surfaces using a damp cloth and mild detergent, then dry with a clean cloth.

At AG Millworks, we specialize in crafting high-quality door and window systems for luxurious outdoor living. Our meticulous craftsmanship ensures that our doors are not only easy to maintain but also experience fewer maintenance-related issues.
