A friend of mine told me that while he was in Fl. and old GENT told him that he found that washing his trailer with Dawn Dish Soap did a good job. I have washed my travel trailer three times now and it came out fine. Very little water spots (and I have well water) and it looks like I have waxed it. My trailer is fiberglass sided and a newer trailer. I have always waxed my trailers every year but now I use Dawn Dish soap original. In fact I just came in from washing it and it looks great !! I know waxing it would be better but this works for me.
Using dish soap removes any protective finishes (wax) that was on the trailer... You should only use automotive soaps.
