cleaning Canvas

[mercc350]

Getting ready to clean the canvas on my Jayco 1206. My question is after I throughly clean it and rinse the entire thing do I need to re-apply the water proofing chemical? If so what products are recomended? I also noticed a post that when using a bleach solution that a good rinse is required. I have only one area on my canvis that has mildew on it. Anyone have a good way of rinsing this on the inside? Thanks in advance.
