Just a few words about safety. To clean and wax the RV can involve ladders and time on the roof. If you’re not physically up to the task don’t try it, instead pay for the service. Falling off an RV roof can seriously injure or kill you. Working at that height shouldn’t be considered lightly. Up on the roof I use a boating type deck shoe with very good gripping soles and stay in the middle, avoiding as much as possible being near the edges. Also take your time and be organized this not a place to be tripping over things. When climbing the ladder to reach high areas it’s a good idea to have someone hold the ladder for you. Always have someone around so if you do fall they can quickly get help.
