The first thing to note is that the aluminum frame cannot be used for cleaning, nor can the frame be used as a support, which will cause more damage to aluminum doors and windows.
Aluminum doors and windows can be dipped in clean water or neutral detergent with a soft cloth. Avoid using ordinary soap and washing powder. Do not use strong acid and alkali cleaners such as dirt powder and toilet detergent, otherwise it will corrode the profile.
If the sealing top and glass glue are found to fall off, they should be repaired and replaced in time. Ensure the airtightness and heat preservation of aluminum doors and windows.
After the rain, the glass and window frames should be wiped dry in time.

Check the joints of the door and window frames frequently, tighten the bolts in time, and replace damaged parts. The vulnerable parts of aluminum alloy doors and windows, such as positioning shaft pins, wind braces, and floor springs, should be checked frequently and lubricated regularly to keep them clean and flexible.
In the use of aluminum doors and windows, the action should be light, and the push and pull should go with the flow; if you find that there is difficulty, do not pull or push, and troubleshoot first. Dust accumulation and deformation are the main reasons for the difficulty of pushing and pulling aluminum alloy doors and windows. Keep the door frame clean, especially the sliding groove. A vacuum cleaner can be used to remove the dust accumulation in the groove and the door seal top.
Always check the wall joints of aluminum doors and windows. If the aluminum doors and windows are loose, it is easy to deform the frame as a whole, so that the doors and windows cannot be closed and sealed. Therefore, if the screws of the joint are loose, they should be tightened immediately. If the base of the screw is loose, apply a small amount of cement to seal with epoxy strong glue.
