Any window, no matter what material it was made of, requires some maintenance. And windows made of metal-reinforced plastic are no exception. Caring for such structures is not so difficult, but it must be made with certain rules. You do not need to use special expensive means and materials, all work is done with the usual «improvised» means.
In order to clean a plastic frame, it is sufficient to use a normal soapy solution or a special agent provided for the care of products made of metal plastic. It is strictly forbidden to use for these purposes cleaning agents which contain solvents, acetone, abrasive substances, or acid.
Special cleaners are usually sold in the companies which install or sell plastic windows in St. Petersburg. Such a product or soap solution is applied to the surface of the frame with a soft cloth, and then washed off with water. In the process of cleaning the window frame it is necessary to avoid hitting it or making scratches. It is better to clean double-glazed windows with pure water with a normal window cleanser added.
Modern materials are used for manufacturing seals for plastic windows. But, despite this, they are still subject to natural aging, so, to increase their service life, experts recommend caring for them at least 2 times a year. In the process of maintenance it is necessary to produce their cleaning from dust and dirt, lubrication with a special agent that contains silicone oil. Thanks to such measures, the seals will be elastic and have water-repellent properties for a long time.
To increase the service life of fittings and to preserve its flawless appearance for a long time, it is necessary to lubricate all the moving parts of mechanisms with oil, which does not contain acids and resins, 1-2 times a year.
