The windows began to close tightly. The master said: "you killed the fittings with grease"

Hello, friends.

I try to be careful with things. If the installer says, “once a year, plastic windows need to be lubricated,” I do it. That's just out of inexperience so smeared that I had to repair the fittings. Let me tell you more so that you do not repeat other people's mistakes.

I am sure that you have heard more than once from installers that window fittings need to be lubricated. Just how to lubricate it?

In a hardware store, I found a bottle with a magical inscription: "for window fittings." I bought it. Began to use. What could go wrong here? However, after 5 years the hardware began to work much tighter. Sometimes even with a creak. I called the installer.

The craftsman examined the fittings and made a diagnosis: "for repair". At the same time, he explained that without my lubricant, she might have lived much longer. He explained what the problem was.

Window grease should be sufficiently liquid and penetrate deeply into the mechanism, reducing friction of parts. In funds from stores

marketing is much more than the lubricant itself. They can, of course, be used, but only on one condition.

The fittings must be thoroughly cleaned before lubrication. If this is not done, the dust that has settled on the surface is retained by the oil. This mass becomes abrasive and contributes to the wear of parts. Therefore, there are squeaks, a tight handle and jamming.

I was outraged that it would hardly be possible to completely clean the mechanism on my own. In response, the master told a trick that greatly simplifies this work.

He took out a spray of lithium grease. This grease contains detergent components. At first we spray a little, without shaking the bottle. The liquid perfectly dissolves old thickened oil and dirt. We wipe the surface with a napkin. Shake the bottle well and apply grease to all rubbing parts - it's done.

The limitation period of this story is about five years. All this time I have been using similar aerosol lubricants. The fittings are working properly. Windows open and close as if they were just installed yesterday.

That's all for me today. If the material was useful to you, do not forget about the "thumbs up".Subscribe to the channel here.
