On plastic window sills often there are fairly stable spots that are not so easy to fight. Fortunately, there are several secrets to keep the window snow-white.
Wash, not wipe
Plastic window sills often have a slightly porous structure, so it is not enough to wipe dust off them. It is better to wash them with microfiber cloths to remove all dirt.
Use for cleaning soap
Constantly wash the window sill with this inexpensive means to prevent the formation of stains.
Ammonia for colored stains
This tool can help get rid of traces of a felt-tip pen or a ballpoint pen. If there is no pure chemical, use window cleaner.
Stubborn dark spots
In case of darkening or yellowing, make a mush of laundry detergent for white things. Apply the paste to the stains and leave for a few hours. In case of heavy dirt, apply the product to the entire surface.
Vinegar will save rust
Acid cope with such complex stains. In addition, you can use for this purpose lemon juice. Remove the most serious contaminants with concentrated vinegar essence.
Bring whiteness to sill with chlorine
The most convenient way to use bleach in the form of a gel. Apply it on the entire surface of the window sill, and after half an hour, rinse with clean water.
