Screen cleaner spray has long been a necessary accessory for any business or person who spends hours working in front of a computer screen. If you are going to be working on a computer, or want better visibility of your screen, it's important to keep it clean! You don't want to damage your eyes or nose. Your seats or desk can become littered with dust and dirt after being used for multiple hours a day. They also tend to collect fingerprints and smudge marks from fingers that used the same place over and over again.
