Computers can become very dirty and dusty because of the static. You can cut static by wiping the exterior of your monitor and the surrounding wires and pieces with a cloth dampened with vinegar. Vinegar will de-static these pieces thus preventing dust from clinging.

Using a half and half mix of ammonia and water or vinegar and water, you can clean the dirtiest portions of your keyboard. This will get the grease out that has been accumulating from your skin. For a more thorough clean use alcohol with a cotton bud or ball will clean the most detailed pieces of your computer keyboard.

If you work with a laptop PC then you may well find that the finger touch control pad quickly becomes unresponsive, sticky or un-smooth. When the laptop is switched off, just dampen a kitchen towel with a little vinegar and wipe all around the control pad. When your laptop is switched back on you will find the pad responsive and smooth once again.

If you find that your ball mouse is not running as smoothly as it first did. You will find that it has become clogged with dust and fluff. Underneath the mouse you can slide the ball cover anti clockwise and release the ball. In the hole that is left you will find 3 rollers that the ball runs in. These rollers should have nothing on them. However you will find that they have become clogged with dust and fluff. Remove all the dust and fluff with a pair of tweezers and blow clean. Once reassembled you will find that the mouse runs smooth again
