The best way to prevent corrosion is to
keep your vehicle clean and free of cor
rosive materials. Attention to the under
side of the vehicle is particularly
important.

High-corrosion areas
If you live in an area where your vehicle
is regularly exposed to corrosive materi
als, corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
-
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 pre
vent corrosion. In winter, hose off the
underside of your vehicle at least once a

month and be sure to clean the under

Moisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by
When cleaning underneath the vehicle,
give particular attention to the compo

that are hidden from view. Do a thor

will accelerate corrosion rather than pre

such conditions, the corrosive material is

tact with the vehicle. Although the mud
appears to be dry, it can still retain the
moisture and promote corrosion.
When cleaning lower door panels, rocker
panels and frame members, be sure that
drain holes are kept open so that mois
ture can escape and not be trapped
inside to accelerate corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly

clean and free of mud or accumulations
of other materials. This applies not only
to the visible surfaces but particularly to
the underside of the vehicle.
Keep your garage dry
Don't park your vehicle in a damp,
poorly ventilated garage. This creates a
favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered
with snow, ice or mud. Even a heated
garage can contribute to corrosion
unless it is well ventilated so moisture is
dispersed.
To help prevent corrosion
You can help prevent corrosion from
beginning by observing the following:
