In April when I came home from Florida I let my awning out and give it a good cleaning, after drying good I had a brain storm, use Armorall on it, useing a spong mop I did a nice job on it,thinking maybe would help keep it clean, Yesterday thought better wash the awning before gets cold, I let in down and it was unbeliveable, one solid mass of mold, I have been cleaning awnings lots of year but NEVER have I saw one so bad, Did the Armorall do it?? I think so but, I get the bucket put maybe four gallons in it and couple cups of bleach, wet it down and roll it up for one hour, didn,t touch it, did it a few more time, nothing , in about two gallons of water I pour half a gallon of bleach and leave up an hour, it took care of some of it, after few trys I break out the Tilex and sprayed it down and rolled up maybe 30 min later had taken most of it off, wondering when I get to Florida this winter and unroll my Awing will it still be in one peice are melted, even tho I washed it down very good, hope in Dec there will be a day warm enough can look at it before I go and clean it again, The Awning is 3 years old
