Maintaining the System D-3
5HFRPPHQGHG7RROVDQG$FFHVVRULHV
Dell recommends that you use the following tools and accessories when you clean
the system:
‡
A wrist-grounding strap
— The proper use of a wrist-grounding strap reduces
the effect of electrostatic discharge (ESD), which can damage certain system
components. To use a wrist-grounding strap, place the strap around your wrist
and attach the other end of the strap to an unpainted metal surface in the
chassis, such as the power supply bracket, that is connected to chassis ground.
‡
A liquid dishwashing detergent —
Use a mixture of one part liquid dishwashing
detergent and three parts water to clean the exterior of the system, monitor, and
keyboard. You can also add fabric softener to produce an antistatic solution that
prevents dust from being attracted to the monitor screen.
‡
A soft, lint-free cleaning cloth
— Moisten the cleaning cloth with the dishwashing
detergent solution to clean the exterior of the system.
‡
A nonabrasive diskette-drive head-cleaning kit
— Dell recommends that you use
a kit that contains pretreated diskettes in individually sealed packages. These kits
ensure that the cleaning solution is applied evenly over the entire diskette-drive
head surface, and they prevent contamination of the heads by exposure to
foreign substances.
‡
A small vacuum cleaner with a brush attachment
— Use the vacuum cleaner to
remove dust and dirt from the exterior of the system and keyboard.

A conventional monitor or keyboard cover minimizes the accumulation of dust and
other debris inside the monitor and keyboard when they are not in use. Also,
commercially available keyboard membrane covers make it possible to use the
keyboard while providing protection against foreign particles.
However, regardless of any protective covers, the monitor and keyboard must be
cleaned occasionally. To clean the exterior of the system, monitor, and keyboard,
follow these steps:
1. Turn off the system, monitor, and any other attached peripherals, and disconnect
them from their electrical outlets.
2. Use a vacuum cleaner to remove any dust from the slots and holes on the
system and between the keys on the keyboard.
3. Moisten a soft cleaning cloth with a solution of three parts water and one part
liquid dishwashing detergent.
Do not soak the cloth in the solution; you must not let the solution drip inside the
system or keyboard.
4. Use the moistened cloth to wipe the system cover, the keyboard, and the
exterior of the monitor, including the screen.
