TREK 2005 Exterior & Interior Care --- Section 3 • 91
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, wheel openings and radiator 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 minimize 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. Damage to the fins can result when
using a high pressure washer or steam cleaner. Nozzle discharge 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
specifically designed automotive detergents. Do not use 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
openings, 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 sandpaper,
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 and
work toward the bottom. Try to 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.
