Washed my roof, but Dicor is growing mold.

I washed my roof for the first time since we bought it almost two years ago. The rubber cleaned up great and is still in good shape. However, the Dicor goo around all the vents, a/c etc are growing black mold. Is there a product to kill this or stop the growth without damaging the roof. I used Camco RV wash for cleaning the roof.

Same problem here. I'm getting ready to do a Dicor roof touch-up. Gonna pull my Maxx-air vents also to check around vents. There's a Dicor video on You-Tube that says to clean the caulk ONLY with mineral spirits wiped on with a rag, being very careful not to allow mineral spirits to contact the rubber roof. I was thinking about doing that or maybe using a diluted bleach spray to clean the caulk before applying the touch-up.

I would go with bleach. It's a good way to kill any mold or mildew.

I called Dicor and was told they recommend Tilex mold and mildew remover. The same as you would use in your bathroom.

I have a EPDM and used it and it works great. Just be sure to keep the sides of you unit rinsed well to prevent streaking from the Tilex.

Got the same mold problem and I'm going to try Tilex.

Thanks Archbarb, that was a good link. Just wish I would have known about it last week!

I'm confused. Jayco told me that all the products installed on my coach are Alpha Systems.

I called it Dicor in my post, but it could be some other brand gooey sealant around the penetrations and seam. I am not sure what my roof is made of.
