How to Clean the Outside of a Camper Trailer Steps  


Do not wash in the blazing sun. Before you start cleaning the outside of your camper, find a suitable location. Make sure that the camper is not in direct sunlight. A nice, shady spot is not only more comfortable for you but also for your mobile home. The major reason for this is because detergents dry faster in direct sunlight, leaving behind unsightly streaks and stains. It’s also best to park the RV slightly on a slope. It allows the rinse water to drain more easily from moldings and other debris. Next, allow the outside surface of the RV to cool completely. 


Start by wetting the entire RV with a medium-strength water spray from a garden hose to loosen surface dirt and small debris. Next, rinse the roof carefully and work it down. (You would need to stand on a ladder to spray the roof properly). 


Mix the car wash liquid soap with water in a clean plastic bucket. For best results, use the amount of soap and water recommended by the soap manufacturer. Use the soap above I had recommended. 


Wash the camper roof with the soapy solution and Lamb’s wool washing mittens. Work this in 3 x 3-foot sections and rinse each section with water from the garden hose immediately after washing. Also, periodically wash the lambs wool washing mittens with fresh water to avoid reapplying abrasive particles to the camper’s exterior finish. 


Dry the roof with microfiber towels to prevent water spots from forming. 


Clean the sides, front, and back of the RV trailer using another lambswool mitt. Follow the same cleaning process as for the roof. Focus on one section of the RV wash at a time. 


Wash the wheels and tires. When it comes to the wheels, thoroughly splash water on the dirty surfaces around the wheel housing. This is quite important because this part easily accommodates mud and dust. It is also best not to leave any encrusted mud or the leaves in the wheels if you do not travel with the camper again in months.


Look at the engine, open the hood, and clean it, as leaves and other debris from your trip usually remain in this section.
