This section is on general
cleaning and maintenance.
Some of the articles within
“Exterior & Interior Care
- Section 3” may not apply
to all models. Improper or
inadequate maintenance
may affect your warranty
coverage. Please review this
section carefully. For more
information, see the terms
and conditions of the Limited
Warranty in the front of this
Manual.
EXTERIOR CARE
Corrosion
The most common cause of
corrosion to the motorhome
exterior is accumulation of
road salt, grime and dirt. These
elements, combined with
moisture, may possibly cause
early component failure. The
undercarriage, around wheel
openings and the radiator charge
air cooler package require periodic
cleaning to prevent component
failure caused from corrosive
materials collected on roadways.
If the motorhome is stored or
driven in areas where road salts
are used or near the ocean, it
should be washed at least once a
week, including the undercarriage.
Otherwise, it is recommended to
hose off the undercarriage area at
least once a month to help slow the
process of corrosion.
High-pressure washers or steam
cleaners are the most effective way
of cleaning the undercarriage and
inside wheel openings. However,
these devices can cause damage if
used improperly. Avoid spraying
directly at the painted surface with
a high-pressure washer of any
type. Also avoid spraying electrical
wiring, connectors or electro-
mechanical components with high
pressure.
CAUTION:
It is up to the motorhome
owner to properly wash
and protect the motorhome
and its components from
corrosion. Sources of
corrosion can come from
road surfaces treated
with de-icing agents or
atmospheric conditions
such as coastal regions.
CAUTION:
Exercise caution when
cleaning the radiator
charge air cooler package.
Damage to the fins can
result when using a
high-pressure washer or
steam cleaner. The nozzle
discharge pressure of
these devices can exceed
1800 psi. Also avoid
using high-pressure/
high-temperature steam
cleaners on the exterior
paint surfaces. Remove all
spattered washing debris
from the exterior paint
surfaces as soon as possible.
Winter Drive Protection
Various substances and
chemicals are applied to roadways
to reduce hazardous winter driving
conditions. These substances can
include rock salt, sand, gravel
or chemical applications such
as Liquid Magnesium Chloride
(LMC).
Road salts are known for their
corrosive properties to steel and
other metals. Road salt can also
damage other vehicle components
and materials. Vehicles located in
or traveling through areas where
road salt is used are subject to
rapid corrosion. LMC is a moisture
activated chemical applied directly
to the road surface for the purpose
of lowering the freeze point of
water. According to published
information, LMC is a suitable
replacement for road salt or
sanding.
