How To Remove Mold From The Roof Of Your RV?

How To Remove Mold From The Roof Of Your RV?

We are full-time RV'ers and have acquired mold spores on our fiberglass roof (Itasca Suncursier), and everything I've tried so far will not remove it. Can you give me suggestions on what will remove the spores and is there a product that will keep it off?

ANSWER Although I have not experienced any mold problems on any of the RVs I have owned (knock on wood), I do have some suggestions for you. Follow the steps I have outlined below and they should help.

Editor's Note: The information below is for removing mold/mildew from fiberglass RV roofs.

Safety Precautions Since you are going to be dealing with mold, I recommend that you wear long sleeve clothing, safety goggles, gloves and a particle mask that is capable of blocking mold spores. This may seem like overkill, but certain molds can be very harmful if inhaled or ingested. Since you are not sure what type of mold you are dealing with; it is better to be on the safe side.

Now that you are protected, follow these steps:

1. Clean your roof thoroughly using a soft bristle brush. You should use an RV carwash product such as Camco Full Timer's Choice Trailer Glitter Wash. Let the RV roof dry thoroughly.

2. Once the roof has dried, it is time to get rid of the mold. I would recommend that you use a product such as KRUD KUTTER MS32 Mold and Mildew Stain Remover Plus Blocker. Krud Cutter does not contain bleach and the manufacturer says that
it safe to use on fiberglas. It also has a blocker that inhibits future growth of mold.

Before you do the whole roof of your RV, I would suggest you test Krud Kutter on a small area of the roof to ensure that it does not have any ill effects on the fiberglass or Gelcoat. If all is well you should clean the whole roof of the RV following the manufacturer’s instructions. Don't just don't treat the visible stains; some mold may not be clearly visible to the naked eye. You may only need to do this once, but if you still see visible mold a second treatment may be needed.

3. If you still have some small stubborn mold stains on the roof, I would suggest you use a soft sponge with some baking soda to clean it up. Again test a small area of the roof to make sure that the baking soda is not causing scratches (it should not but just make sure)

4. Once the roof is dried and cleaned I would suggest that you put a coat or two of a good Fiberglass Wax on the roof. The wax should repel water and dirt and not allow the mold to appear again.
