Cleaning The Exterior

To protect your recreation vehicle’s exterior finish, wash it often and thoroughly.

For recreation vehicles with painted exterior graphics: If desired you may wash and wax
your vehicle 60 days after purchase. The exterior paint does need time to cure before any

wax is applied to the exterior surface. Careful maintenance for the first 60 days will assure

a long lasting durable finish.

Your recreation vehicle is exposed to many environmental conditions that have an adverse

affect on the paint finish:

Road Salt and Sodium Chloride

Road Tar / Bugs

Bird Droppings / Tree Sap

Industrial Fallout / Acid Rain /Pollution

UV Exposure and Moisture

The most common problems resulting from these conditions are corrosion, staining, and
chemical spotting. Generally, the longer the foreign material remains in contact with the

exterior finish, the more extensive the damage. These problems can be minimized by

regularly scheduled washing and polishing. Wash your recreation vehicle as soon as possible
if it becomes contaminated with foreign material.

Avoid parking under trees or near ocean sea salt. Ice or snow should not be scraped from

the painted surface: Brush off!

Gravel roads should be avoided.

Anti-freeze, gasoline or washer solvents if spilled on the painted surface should be rinsed off

with water immediately. Bugs and bird droppings should be rinsed off daily.

Washing

Commercial washing should be avoided. Wash with cold water using a mild liquid soap.
Dry wiping with a dry cloth is not recommended.

Make sure the RV’s surface temperature is cool, under 90 F, and out of direct sunlight.
A shaded area is ideal for washing your vehicle as direct sunlight causes water spotting.
Use a mild soap, detergent or car wash shampoo. Try to avoid combination wash-n-wax
products as these waxes can cause build up and are designed for smaller surfaces. Have two
dedicated sponges or wash mitts: one for the exterior walls and one for the wheels and under
carriage. Brushes or wash mitts made of plastic bristles are acceptable for use on tires and
wheel wells, but are not intended for use on the exterior walls. Avoid using such items on

painted surfaces as they will damage the finish. Wash the wheels and wheel wells first as

this removes heavy dirt and debris and prevents it from splattering on panels. Wet the entire
area down to remove loose dirt and grime, then hand wash one area at a time using your

dedicated paint finish sponge or wash mitt. Wash from the top and work your way down,

rinsing frequently to minimize grit abrasion. Follow with a final rinse of water. This process

will remove most contamination from the recreation vehicle’s surface.

For stubborn stains such as road tar or bug stains, use an ammonia based glass cleaner or
a small amount of rubbing alcohol on a damp cloth followed immediately by warm soapy
water, and rinsing with clean water. This may not dissolve the road tar, but it will loosen tar
and bug stains and remove them from the surface.

Do not use solvent based cleaners on bird droppings or tree sap as these are water based
