EXTERIOR CARE
-
Corrosion
The most common cause of corrosion to the motorhome exterior is accumulation of road salts, 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 from roadways. If
the motorhome is driven in areas where road salts are used it should be washed at least once a week.
Otherwise, it is recommended to hose off the undercarriage area at least once a month to help mini-
mize the corrosion process. High pressure washers or steam cleaners are the most effective way of
cleaning off the underside and inside wheel openings.
Avoid directly spraying the painted surface
with a high-pressure washer
.
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. Nozzle dis-
charge pressure can exceed 1800 psi. Avoid using high pressure steam cleaners on
the exterior paint surfaces. Remove all spattered washing debris from the exterior
paint surfaces as soon as possible.
Washing
Periodic cleaning will help to preserve the paint finish. The motorhome is painted with a “base
coat, clear coat system.” Clear coat is a polyurethane-based material which brings out the shine and
luster to the base coat paint. Care should be used when washing the motorhome. Use only mild
detergents or preferred specifically designed automotive detergents. Avoid using abrasive cleansers or
laundry detergents that will scratch the clear coat and leave a soap film. Use a soft cloth to wash the
paint finish. Avoid using brushes as they can scratch the surface and damage the paint. Before
washing the motorhome, remove most of the accumulated dirt and “road wash” behind wheel open-
ings, below the windshield and on the rear of the motorhome. If build up is excessive, run water over
a soft cotton cloth while gently wiping the surface in one direction. This will help float away the
“build-up” from the clear coat. Avoid back and forth or circular motions as this may act like sand-
paper, scratching the clear coat and leaving a haze or “swirl marks.” After removing the heavy build-
up, use the mixed detergent solution to wash the motorhome. Start washing at the top of the
motorhome working towards the bottom. If possible, wash the motorhome in a shaded area when the
exterior is not hot to the touch. If necessary, turn the motorhome around to keep the area being washed
in the shade. Try not to allow the detergent to dry onto the clear coat surface. Use plenty of water
when rinsing the surface to remove all detergent residue.
