Aluminium doors and windows are widely used due to their durability, rust resistance and good appearance. However, regular maintenance can extend their service life and keep them in good condition. The following is the details:

Regular cleaning

Surface cleaning

1. Use a soft cloth or sponge dipped in a diluted solution of neutral detergent (such as dish detergent) to remove dust and stains.

2.Avoid using strong acids, strong alkalis or corrosive cleaning agents (such as toilet cleaners and scouring powder) to prevent corrosion of the surface coating.

3.Stubborn stains (such as cement stains) can be gently scrubbed with a special aluminium cleaner.

Track cleaning

1.Use a vacuum cleaner or a soft-bristled brush to remove sand and dust from the track to prevent blockage and affect opening and closing.

2.Stubborn dirt can be cleaned with a cotton swab dipped in alcohol or neutral detergent.

Glass cleaning

Spray with glass cleaner or white vinegar water (in a 1:1 ratio), then wipe with a lint-free cloth or newspaper to avoid water stains.

Check the hardware accessories

Lubrication maintenance

Check the hinges, pulleys, locks and other hardware every 3 to 6 months, and add a small amount of lubricating oil (such as WD-40) to keep them flexible.

Avoid using cooking oil as it is prone to dust accumulation.

Screw fastening

Regularly check if the screws are loose, especially for frequently used doors and windows, and tighten them in time to prevent deformation.

Replace the damaged parts

If rust, breakage or malfunction of the hardware parts are found, replace the parts of the same model in time.

Maintenance of sealing strips

Cleaning and protection

Wipe the sealing strip with a damp cloth to prevent aging and adhesion.

Apply a small amount of silicone oil or petroleum every six months to maintain elasticity and prevent cracking.

Replace the sealing strip

If deformation, detachment or air leakage of the sealing strip is found, it should be replaced in time to ensure the sealing performance.

Drain hole inspection

Regularly check the drainage holes at the bottom of the window frame and clear them with thin iron wire or toothpicks to prevent rainwater from accumulating and causing corrosion or leakage.

Avoid external force damage

Opening and closing force

When sliding doors and windows, avoid excessive force. Especially when there are foreign objects on the track, they need to be cleaned up first.

Sharp object protection

Avoid scratching the surface with hard objects. Do not use steel wool balls when cleaning.

Typhoon weather

Lock the doors and windows in advance on strong wind days to prevent deformation caused by wind pressure.

Coating maintenance

Anodized or powder coated

Minor scratches can be spot-applied with special touch-up paint. Severe damage requires professional repair.

Avoid prolonged direct sunlight. It is recommended to check the coating condition annually in areas near the seaside or with acid rain.

Seasonal maintenance

Before and after the rainy season

Check whether the sealant at the joint between the window frame and the wall is cracked. If necessary, reapply the sealant (silicone weather-resistant sealant).

Winter

In extremely cold regions, be sure to clear the ice on the tracks and avoid for forcibly opening windows which may cause deformation of the hardware.

Frequently asked questions handling

Switch card clock

When the switch stops, check if the track is deformed or if the hardware is short of oil.

Water seepage and air leakage

Adjust the pressure of the hardware or replace the sealing strip.

Abnormal noise

Tighten the screws or lubricate the hinges.

Summary

Through the above maintenance, aluminium doors and windows can remain in good condition for more than 10 years. If the problem is beyond the scope of self-repair (such as severe deformation or water seepage), it is recommended to contact professional maintenance personnel for handling.
