How do I Make my Screen Protector Sticky Again?

Using a screen protector on your smartphone might seem easy at first but if you are not careful enough, there is a chance that you will mess up the whole installation process and deem your screen protector useless. It is known that these protectors are not reusable so if any dirt gets between the screen and the sticky side of the protector, its pretty much over. Although, what if I told you that there might be a way to clean your protector and MAYBE restore its stickiness.
