Machines build up excessive dust that settles and remains until it is baked on.
This prevents the machine from cooling properly and eventually, components break down from excessive heat buildup. Dirt and dust are very abrasive on moving parts like drive heads, keyboard contacts, printer gears, etc. Also, dirty and unsanitary computers and office equipment are a factor in the spreading of sickness in the work place. Because image is very important in business these days, make sure your customers are getting the right impression. In addition to this, it is much healthier and enjoyable to work with clean, sanitized office equipment.
