Cleaning my computer screen

I had to clean my computer screen today because it was just so incredibly dirty! When other people use it, they tend to touch the screen- ahem Libby! and it leaves these awful finger prints!  She claims that when she touches her computer screen it doesn't mess it up. but sure does mine! Now that I have it all clean and shiny it looks so much better than it did before.  I'm glad because it really irks me when it is dirty but I have been too busy to clean it until now. Phew, glad I got that done.
