Modern plastic window sills become dirty and turn yellow very easily. The reasons for this are very different – from unsuccessful watering of flowers to the weather outside the window. How to bleach a plastic window sill from yellowness, we will tell you further.
How to whiten a window sill from yellowness – why do they change color?
Experts say that there are several reasons why plastic window sills turn yellow. One of them is weather conditions. Many manufacturers save money and do not cover window sills with light-resistant film. Therefore, under the influence of sunlight, the color of the material may change. Humidity can also affect this, because in the cold season windows often fog up.
Other causes of yellowness include the following:
- low quality materials,
- poor care (incorrect cleaning products, insufficient washing),
- improper installation (during the installation of windows, craftsmen could wash off the mounting foam with materials that spoil the plastic).
So that you don’t have to figure out how to whiten the window sill, before installing the windows, be sure to ask the seller if they have a light-resistant film and how to properly care for them.
