Well I found a nice 8.5 x 16 enclosed the other day and got a pretty good deal on it but it does need a pretty good cleaning. Its a 2006 model and the fella took it back and forth to florida from ohio for bike week since new. Never washed the trailer once. it has the nasty grimey look running down the sides. Anyone had any experience with what products work best for cleaning the enclosed trailers??????? I actually took some "mean green" from the dollar store and sprayed a small area and let it sit for a few minutes and then scrubbed it and it worked great, then the wife said that the back of the bottle said not to use it on painted metals....... Any help would be appreciated!!!! Thanks fellas!
