During use, plastic can change its color: instead of the spectacular white color, we observe the appearance of an incomprehensible yellow coating.
This does not mean that it is time to replace all sockets and switches that have lost their presentable appearance.
It is quite possible that the problem can be dealt with in just a few minutes using some proven tools.
This method is very simple and has been tested for years. If necessary, it can be used on a large area - for example, if your plastic window sill has turned yellow.
To do this, you need to prepare a fairly strong concentrate. To do this, grind a piece of laundry soap into shavings and combine it with boiling water.
The resulting composition is applied to the plastic for literally 10-15 minutes.
This method may seem even simpler. You need to take two glasses of water and dilute in them just one spoon of any bleach.
The product must be mixed thoroughly.
Then we apply it to the yellowed plastic for literally five minutes.
