Apologies in advance if this is the umpteenth thread on this subject but I need thought and opinions on routine cleaning of the roof, the times in between using a mail ordered or trip to the RV dealer store bought cleaner and conditioner. So, here's my question, I have heard Dawn dish detergent both highly recommended, and been told DO NOT USE IT because anything that cuts grease is not good for a rubber roof, so after using it more than once I am concerned. I just finished cleaning and re-caulking the roof and used a combination of Johnsons Baby Shampoo and vinegar, please don't laugh I saw it recommended on the interweb, but so wasn't the Dawn!!!!!
Ya'll tell me what you're preferred choices are so I can settle on something safe and effective. Thanks!
