Power awning cleaning question

[Grasshopper]

This is the first trailer that I have owned that has a power awning. It has been here long enough to need cleaning and I realized that I don't know how to get to the top side if the awning to clean it. Is there a way to lower the extended awning like you can on the manual ones? Even from the roof it isn't possible to reach the whole thing.

Grasshopper,

If you apply the cleaning solution (1/4 cup dish soap, 1/4 cup bleach, 5 gallons fresh water) to the underside and then roll the awning in and let it sit for 5 minutes, both surfaces will get cleaned. To see how this works, take a piece of paper and mark one side, then roll it up. The marked side rolls up in contact with the unmarked side.

After 5 minutes, open the awning and rinse top and bottom.

Here's a link to a Dometic Tip Sheet that includes their recommended mixture for a cleaning solution.
