If you're running any version of Microsoft Windows and are encountering issues with the mouse wheel, first attempt to adjust the mouse settings through the Mouse Properties window. This window can be accessed by opening the Control Panel and double-clicking the Mouse icon. How can I clean my keyboard? The keys on a keyboard are only clipped on, with a knife or other thin object, carefully pop the keys off, this will allow you to clean under the keys as well as cleaning the keys themselves (make sure you remember where they went!).
