Now, no matter what we do, we need to be professional. Even if we buy invisible screens, we not only have high quality requirements, but also understand the after-sales maintenance. Today, Xiaobian will discuss with you how to do professional maintenance for trackless screen windows?

First, after installation, we check the fasteners at the corners of the door and window frame. If the screws are found to be defective or loose, we should contact the after-sales service personnel for replacement in time. If the screws of doors and windows are found to be a little loose, they must be repaired in time. If they are forced to continue to use, the doors and windows may fall off and cause injury to personnel.

We usually can't disassemble doors and windows and accessories by ourselves or change the structure and format of doors and windows without permission. If necessary, we should contact professionals to solve it on site. After the screen is used for a period of time, silicone oil lubricant (release agent) can be sprayed onto the track (Paraffin polish is strictly prohibited), so as to enhance the flexibility of pushing and pulling and the service life of the screen.

Finally, cleaning is also a very important maintenance method. The removable inner fan shall be cleaned regularly. The groove and slide rail of the window sash shall be cleaned every three months to prevent the accumulation of dust, sand and stone from adversely affecting the normal use of the screen window. Soft wool or vacuum cleaner can be used for cleaning.
