Another question on cleaning the roof of my Bighorn. On my last 5ver, I used the Protect All rubber roof cleaner and rubber roof treatment with UV protection after noticing mold spots. Prior to using those, I just used a mild soap to wash the rig. When I covered the rig in storage with an ADCO cover, it evidently created the mold underneath, even though the ADCO covers are supposedly breathable. I don't want to make the same mistake with our new Bighorn. The manual says to use a mild soap and that other roof cleaners and treatments are not needed. I don't want to have the mold problems again so what do you all suggest. I did purchase a new Aqua Shed ADCO cover since it will be stored on the rainy side of Oregon. Thanks for any suggestions.
