Dell recommends that you use the following tools and accessories when you clean
the computer:
A wrist grounding strap — The proper use of a wrist grounding strap reduces the
effect of electrostatic discharge (ESD), which can damage certain computer com-
ponents. 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 computer, monitor(s),
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 computer 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 for-
eign substances.
A small vacuum cleaner with a brush attachment — Use the vacuum cleaner to
remove dust and dirt from the exterior of the computer 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, commer-
cially 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 computer, monitor, and keyboard,
follow these steps:
Do not soak the cloth in the solution; you must not let the solution drip inside the
computer or keyboard.
