As I've warned so many times on these forums, when using Mr. Clean Magic Eraser, you simply wipe with it wet. Do not scrub. Then dry with a soft cloth or towel. Don't scrub. I've been using it for almost 20 years now on 4 different campers and tents. The secret is a light wipe.
To do the middle, I simply put the eraser on the top of the awning, use my soft brush on a stick and slide it up and down where I can't reach.
My previous TT had a manual awning. I was able to drop the awning like this to VERY easily get to top side. My current one is an electric awning. I can't drop it. I now have the Mr. Clean Eraser mop (on a stick), which is now great!
