I tried searching the forum and the web but typing in the words cleaning and fifth wheel brings up an overwhelming amount of information not necessarily related to what I am looking for. Has anyone discovered any thing that would clean the lower portion of a fifth wheel? It is the lower skirting that I believe they call J wrap. The rest of the RV is spotless but I cannot get that portion clean. I have used many types of heavy duty cleaners with no results. Anyone found something that might help beside painting it? The arrow points to the area I am having trouble cleaning.
