While camping recently in Texas, we parked our Mobile Suites under a huge Oak Tree for 4 weeks. Our roof is now covered in gold/tan colored stain spots that just won't come out. Have tried Tide detergent, and rubbing Alcohol as described by an RV dealership.
Any one know what can be used on the roof without hurting the rubber covering?
Anyone ever tried the spray on rubber roof cleaner and conditioner by Camco? Any other products I need to try??
