Maintenance
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to
occur. For example, corrosion is
accelerated by high humidity, par-
ticularly when temperatures are
just above freezing. In such condi-
tions, the corrosive material is kept
in contact with the vehicle's surface
by moisture that evaporate slowly.
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 retain moisture and
promote corrosion. High tempera-
tures can also accelerate corrosion
of parts that are not properly venti-
lated so the moisture can be dis-
persed.
For all these reasons, it is particu-
larly important to keep your vehicle
clean and free of mud or accumula-
tions of other materials. This applies
not only to the visible surfaces but
particularly to the underside of the
vehicle.
To help prevent corrosion
You can help prevent corrosion from
getting started by observing the
following:
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 par-
ticularly 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
vehicle, give particular attention
to the components under the
fenders and other areas that are
hidden from view. Do a thorough
job; just dampening the accumu-
lated mud rather than washing it
away will accelerate corrosion
rather than prevent 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 mem-
bers, be sure that drain holes are
kept open so that moisture can
escape and not be trapped inside
to accelerate corrosion.
Keep your garage dry
Don't park your vehicle in a damp,
poorly ventilated garage. This cre-
ates a favourable environment for
corrosion. This is particularly true if
you wash your vehicle in the garage
or drive it into the garage when it is
