Plastic is a durable and inexpensive material, so it is often used to make window sills.
Also, many people have plastic windows in their homes, which can also turn yellow.
As it turns out, returning the white color is incredibly simple.
What trick should housewives know about?
If you are looking for an inexpensive and effective method, then it is best to use regular laundry soap. Therefore, you need to take half a standard bar and grind it with a grater.
Then we put the prepared shavings into a bowl and add 200 ml of hot water.
After the product has acquired a uniform texture, you can proceed to the procedure itself. First, clean the windows and window sill from dust and dirt using a damp sponge. You can add a little detergent.
Then we apply the prepared concentrated laundry soap to the most contaminated and yellowed areas.
After half an hour, wash off the product and evaluate the result. If necessary, this procedure can be carried out several times in a row, since it does not cause any harm to the plastic.
