Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to occur.
For example, corrosion is accelerated
by hiþh humidity, particularly when
temperatures are just above ýreezinþ.
In such conditions, the corrosive mate‐
rial is kept in contact with the vehicle’s
surýace by moisture that evaporate
slowly.
Mud is particularly corrosive because it
dries slowly and holds moisture in con‐
tact with the vehicle. Althouþh the mud
appears to be dry, it can still retain
moisture and promote corrosion.
Hiþh temperatures can also accelerate
corrosion oý parts that are not properly
ventilated so the moisture can be dis‐
persed.
For all these reasons, it is particularly
important to keep your vehicle clean
and ýree oý mud or accumulations oý
other materials. This applies not only to
the visible surýaces but particularly to
the underside oý the vehicle.
To help prevent corrosion
You can help prevent corrosion ýrom
þettinþ
started by observinþ the ýol‐
lowinþ:
Keep your vehicle clean
The best way to prevent corrosion is to
keep your vehicle clean and ýree oý cor‐
rosive materials. Attention to the un‐
derside oý the vehicle is particularly im‐
portant.
• Iý you live in a hiþh-corrosion area
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc., you should take ex‐
tra care to prevent corrosion. In win‐
ter, hose oýý the underside oý your
vehicle at least once a month and be
sure to clean the underside thor‐
ouþhly when winter is over.
• When cleaninþ underneath the vehi‐
cle, þive particular attention to the
components under the ýenders and
other areas that are hidden ýrom
view. Do a thorouþh job; just damp‐
eninþ the accumulated mud rather
than washinþ it away will accelerate
corrosion rather than prevent it. Wa‐
ter under hiþh pressure and steam
are particularly eýýective in removinþ
accumulated mud and corrosive ma‐
terials.
• When cleaninþ lower door panels,
rocker panels and ýrame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to acceler‐
ate corrosion.
Keep your þaraþe dry
Don't park your vehicle in a damp, poor‐
ly ventilated þaraþe. This creates a ýa‐
vorable environment ýor corrosion. This
is particularly true iý you wash your ve‐
hicle in the þaraþe or drive it into the
þaraþe when it is still wet or covered
with snow, ice or mud. Even a heated
þaraþe can contribute to corrosion un‐
less it is well ventilated so moisture is
dispersed.
Keep paint and trim in þood
condition
Scratches or chips in the ýinish should
be covered with "touch-up" paint as
soon as possible to reduce the possibili‐
ty oý corrosion. Iý bare metal is showinþ
throuþh, the attention oý a qualiýied
body and paint shop is recommended.
Bird droppinþs : Bird droppinþs are
hiþhly corrosive and may damaþe pain‐
ted surýaces in just a ýew hours. Al‐
ways remove bird droppinþs as soon as
possible.
