How to clean upvc profile and upvc windows ?
In order to give full play to the advantages of plastic steel doors and windows, and extend the service life of plastic steel doors and windows, in the course of use, attention should also be paid to the maintenance and maintenance of plastic steel doors and windows:
1. The dust on the doors and windows should be cleaned regularly to keep the doors, windows, glass and hardware clean and bright.
2. If the doors and windows are contaminated with oil stains and other difficult to clean things, you can use Jieer Liang to scrub, and it is best not to use strong acid or strong alkali solution for cleaning, which will not only damage the surface finish of the profile, but also damage the surface of the hardware. The protective film and oxide layer cause corrosion of the hardware.
3. The granules and other debris on the inside of the frame should be cleaned in time to prevent the drainage channel from being blocked and causing poor drainage and water leakage.
4. When opening the door and window, the intensity should be moderate, try to keep the speed even when opening and closing.
5. Try to avoid hitting the door or window with a hard object or scratching the surface of the profile.
6. When the door and window are found to be inflexible or other abnormal conditions during use
When the door and window installation team of the assembly factory completes the installation of doors and windows, due to the carelessness of the wall decoration personnel, the thickness of the filling foaming agent often appears uneven or adhered to the steel doors and windows. Sometimes, stubborn marks are also present. At this point, we can:
A. Use a blade to level the area of the fill and smooth it with sandpaper.
B. If the paint is decorated, the shovel can be treated with the same color paint.
C. Scrub the surface of the profile with water to remove general dust.
D. Use a white cotton gauze with ethyl acetate to scrub the stubborn stains, then scrub with water.
