How to Clean Rain Water Stains on an RV Ceiling

Recreational vehicles are used for vacationing and camping as well as for full-time living. Maintenance is an essential aspect of owning a recreational vehicle, as a roof leak or built up condensation can cause brown stains to form on the RV's ceiling. Water stains will cause the ceiling to appear dingy and mar the interior appearance of the recreational vehicle. After the leak or moisture problem is properly repaired, the unsightly brown stains can be removed with simple cleaning solutions.

Pour 1/3 cup of liquid washing powder into a cleaning bucket. Fill the bucket with 1 gallon of warm water.

Dip a cleaning brush into the soapy solution. Scrub the brush over the ceiling to remove the brown stains.

Inspect the ceiling for remaining stains. If the soapy solution did not completely remove the brown stains, pour 1/2 cup of baking soda into a bowl.

Pour 1/4 cup of hydrogen peroxide into the bowl. Mix up the baking soda and hydrogen peroxide with a spoon to form a thick paste.

Apply the paste to the brown stains, using a rubber spatula. Allow the paste to set on the stains for 30 minutes.

Pour some hydrogen peroxide into a spray bottle. Spray the paste with the hydrogen peroxide.

Dampen a clean washcloth with water. Wipe the washcloth over the ceiling to rinse off the paste.

Dry the ceiling with a clean towel. Failure to dry the ceiling can cause water stains to return.


A sponge can be used instead of the cleaning brush.
