A plastic window sill can easily be restored to its original appearance, even if the surface has darkened significantly and there are many stains on it.
To do this, the lower part of the window opening must be wiped not just with a damp cloth, but with a piece of fabric with a special agent applied.
We are not talking about some expensive chemicals.
A homemade mixture made from the simplest ingredients will do a great job of dealing with stains on the windowsill.
How to Make a Window Sill Cleaner
You will need bleach tablets and baking soda.
First, you need to crush a chlorine tablet in a mortar. The resulting powder should be poured into a saucer and mixed with one tablespoon of sodium bicarbonate.
The prepared mixture must be diluted with clean water until a “gruel” appears.
The result will be a product in which you need to dip a cloth or kitchen sponge. After that, the soaked material should be used to wipe the window sill.
All yellow and brown stains will be removed instantly. The surface will become perfectly white again.
Important: Before starting work, you need to put on rubber gloves.
