There really isn't much to do with the slide out awnings as they pretty much clean themselves when you bring the slide outs in. I would clean them a couple times a year for regular camping. If you are going to be set up for an extended lenght of time, I might take a look before I broght the slide in. The only time I have seen a possible problem is when it had rained a lot and then froze. The awning had water collected on it and then froze causing it to sag, but when the slide was brought in, it cleaned the ice out. Because the slide out awnings are enclosed in a spring loaded enclosure they usually keep water off along with leaves and limbs. I have 3 slides with each have a awning over them. When I had my other 5th wheel with a slide out, I had to get on top of the camper and clean the slide before I brought it in, especially if it was under or around trees. With my current camper I don't have to worry about that.
