Just washed the tent ends on our Jayco 23B; used bleach water (50/50 mix) with a little Simple Green mixed in. Sprayed it on with a garden sprayer and let is sit for a couple of minutes, then scrubbed it with a medium brush with carwash soap. The only thing is that I seem to have several small rust-colored spots on the rear tent end and on the awning. I see them clearly from inside the tent end and underside of the awning, but I don't see them on the exterior of the tent end or the top side of the awning. I've tried bleach and I've tried Magic Erasers and I've tried mildew remover separately with no success...anyone see anything like this?
