I've been under some pine trees and got some pine sap droppings on my awning. It sticks to itself when unrolling.
Zip Dee says to only use NON-detergent soap (Ivory Liquid?) to keep from removing the water-repellancy. I'm sure to spot remove the sap will definitely remove waterproofing!
I always keep a supply of ZipDee's own cleaning compound on-hand for the awning on my Overlander. So far, it has removed anything that has been deposited on the awnings. You can learn about the ZipDee cleaning products at:
Well, I called Zip Dee and they referred me to Sunbrella.com for the cleaning directions.
Go here click on RV and then scroll to 'clean' and they have a Word doc or PDF file that you can put in your A/S book on various stains to get out of the acrylic fabric.
They did recommend turpentine followed by Ivory soap wash.
