What did you do to your Class C MH today???

Well the awning and I got a bath today, It was a little dirty. When we were on our trip 2 wks. ago, I was under an awning of another camper, the underside had a lot of black spots some large in size. I suspect that this was mold. I thought that I better get mine clean. I don't think that it is a good idea to let mold grow on a awning. I just love messing with the C.
