Small methods of daily maintenance of doors and windows
Regularly clean the dust on the doors and windows, keep the door and window hardware and glass clean and bright, and regularly clean up the granular debris in the frame to avoid clogging of the drain.
If the doors and windows are stained with things that are difficult to clean, such as oil stains, do not use strong acid or strong alkali solution for cleaning, otherwise it will not only damage the surface finish of the profile, but also cause damage to the oxide layer and protective film on the surface of the hardware and then cause the rust of the hardware.
During the use of doors and windows, if you find that the opening is not smooth or other abnormal conditions, check the hardware system in time. In order to avoid the glass being scratched when cleaning, try to use a special glass cleaner and a special rag.
