Leaks that go unnoticed or unrepaired in RVs cause permanent ceiling, wall or floor damage. Mold growth on the wood walls is unsightly and indicates that at some point it will be subject to delamination, or separation of the wood from the fiberglass shell. RV Living Magazine says, "Every time you wash your RV or every time it rains, do an inspection for leaks in your windows." A few preventative measures and regular cleaning will eliminate the problem completely. Removing mold and mildew takes anywhere from two to four hours, depending on the area involved.
Attach a brush end to a vacuum cleaner wand and gently run it back and forth over all wall areas that are covered in mold. Extend at least 2 feet out from all visible mold.
Mix 2 tbsp. dish soap with 1 gallon of warm water in a small bucket. Soak a rag in the mixture, wring it out and wipe the entire wall that has mold.
Rinse the area with a rag dampened with clear water. Allow a few minutes to dry. If discoloration remains, pour 2 tbsp. mineral spirits on a dry rag. Wipe the entire area well. Rinse again with clear water.
Wipe the wood with paste car wax, using an applicator or dry rag. Once dried, the surface will look hazy. Buff the area with a soft towel.
