It's time to get my MH ready for my first camping trip of the year. I need to clean it, but I am not sure what to use as a cleaner on the roof. I can not climb on top of the camper or reach it with a tool, so I need to do some of the cleaning from a distance (nearby deck). I would like to use Clorox Outdoor Cleaner (spray on, let sit, wash off), which I use to clean the vinyl siding of my house and it does a fantastic job. Since it contains bleach, would it be safe to use on the roof, or would it damage/deteriorate the caulking of the roof seams? I am not concerned about the sides of the vehicle, I have used it there before without any problems.
