If you ever owned an aquarium, you know you have to clean the glass on the inside. Some people do that with a brush that is held to the glass by a magnet on the outside. In that way you can clean the inside glass from the outside by moving the brush up and down the glass.

The same goes for the screen you are watching right now. Up until now there was no such cleaner, but now there is. Just click on the below link and move your cursor.

Good luck.
