I have an enclosed trailer that is parked in a mostly shady section of our yard. On Friday I took the car out to put it away for the season. Today I went to clear out the rest of the things I don't like to leave in the trailer for the winter and noticed that I have mildew/mold starting to grow on the walls. I have not had this problem before, have had the trailer since winter of 2017. I typically leave the roof vent cracked open a little but noticed I forgot to open it after my last trip (about 6 weeks ago) and suspect that is why I am growing things. It poured rain here yesterday and there is no signs of leaks anywhere, jump damp feeling inside. Plywood walls and floor. So a few questions; did I cause this by having the roof vent closed and how do I clean up so I don't have more issues? Will simple green do the trick? Tips for avoiding this in the future. It is not unusual to not go into the trailer for weeks at a time, really don't want this surprise again.
