Exterior
We recommend that you do not take your RV through auto-
matic car washes. Extreme caution should be used if utilizing
any type of pressure sprayer around all attachments, doors,
windows, appliance vents, etc. Avoid forcing water inside the
RV, which could possibly damage component parts.
Do not wash the RV when it is in direct sunlight. Park the RV
in the shade and spray it with water to remove dust. Next,
using an ample amount of clean water and a car-washing
mitt or sponge, wash the RV from top to bottom. Use a mild
car-washing soap if necessary. Rinse thoroughly and wipe
dry with a chamois or soft cloth. Carefully clean the joints and
flanges of the slideout, doors, hood, etc., where dirt is likely to
remain.
Some types of hot water washing equipment apply high pres-
sure and heat to the RV. They may cause heat distortion and
damage to the resin parts and may flood the RV's interior.
Therefore, be sure to observe the following:
1. Keep the washing nozzle about 16 inches (40 cm) or
more away from the RV body.
2. When washing around the door, vent and glass areas,
hold the nozzle at right angles to the surface.
During cold weather
Salt and other chemicals that are spread on winter roads in
some geographical areas can have a detrimental effect on the
RV's underbody. If your RV is exposed to these conditions,
spray the underbody with a high-pressure hose every time
you wash the exterior of your RV. Take special care to remove
mud or other debris that could trap and hold salt or moisture.
After washing your RV, wipe off all water drops from the rub-
ber parts around the slideout and doors.
If the slideout or door is frozen, opening it by force may tear
off or crack the rubber gasket that is installed around the
slideout or door. Pour warm water on the gasket to melt the
ice (wipe off the water thoroughly after opening the slideout or
door). To prevent the weather stripping from freezing, treat it
with a silicone spray.
