Maintenance
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to oc-
cur. For example, corrosion is accel-
erated by high humidity, particularly
when temperatures are just above
freezing. In such conditions, the cor-
rosive material is kept in contact with
the vehicle's surface by moisture that
slowly evaporates.
Mud is particularly corrosive because
it dries slowly and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still re-
tain moisture and promote corrosion.
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the visi-
ble surfaces but particularly to the
underside of the vehicle.
To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-

Keep your vehicle clean
The best way to prevent corrosion is
to keep your vehicle clean and free of
corrosive materials. Attention to the
underside of the vehicle is particularly
important.
• If you live in a high-corrosion area
— where road salts are used, near
the ocean, areas with industrial
pollution, acid rain, etc.—, you
should take extra care to prevent
corrosion. In winter, hose off the
underside of your vehicle at least
once a month and be sure to clean
the underside thoroughly when
winter is over.
• When cleaning underneath the ve-
hicle, give particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will ac-
celerate corrosion rather than pre-
vent it. Water under high pressure
and steam are particularly effective
in removing accumulated mud and
corrosive materials.
• When cleaning lower door panels,
rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.
