Just to drift the subject a little bit, how do you guys with power awnings clean them? Especially if it's been collecting garbage and bird poo from trees immediately overhead?
I tilt my manual one down and can beat the bottom of it with my hand or broom to remove all the loose stuff before closing it, and it's easy to quickly wash off if necessary.
I do the same with my power awning, push both arms in and lock them and sweep it off - no different then a manual awning.
When dewinterizing I roll the awning out, spray it wet and spray Tilex on it and roll it up for 20-30 minutes, unroll and spray it again and it looks like new.
