I hate girls who touch monitors. WTF is that all about? The only guys you see touching monitors are little kids, whereas it seems quite common among girls.
BTW, I use the Kensington Screen Guardian (non-abrasive) and a 3M Scotch-Brite Microfiber Cleaning Cloth. You can pick them up at your local Staples and they work fine for both LCD and CRT monitors.
EDIT: When you spray the cleaning liquid, don't spray on the screen...spray on the cloth and then clean the screen with it. If you spray directly onto the screen, it'll travel down into that crack and might actually ruin your monitor or at least temporarily disable it and give you a good scare.
