Awning From Hell

I have to clean this awning for a large real estate company. It has lichen and a really thick black mold on the exterior surface of the awning. I got the lichen off last night but failed in removing the black mold. Do any of you have any suggestions on what kind of chemicals I should use? I am going to need something pretty powerful (obviously). Thanks a lot.

The chlorine was fresh, I had gotten it on the way to the job. I think the dark stuff is just mold staining or something. I know there are some good chems for cleaning awnings I just want to know which one I should buy.
 
I've done a few buildings with awnings and the chlorine did not affect the color of the awning. They are a canvas material. I wet them before and rinse well after and the chlorine did not change the color at all. I did test the awnings before I sprayed the building to make sure.

It probably is canvas. Is there anything you can recommend besides chlorine? It just isnt cutting it on this job.
 
Since you also live in the south there should be several companies that specialize in canvas coverings for not only awnings but boat covers and t-tops for boats, etc. I would suggest calling them on Monday. They will all probably tell you that they would only recommend a light bleach mixture, but I would call them. It will probably take a little pressure on the canvas (not too much)

Before you do anything else to the awning I would address the problem with the property owner and make him aware of the problems that you are having and make them aware that the removal of the stains could cause damage to that canvas, but you would be as careful as possible and let them make the decision.

Just my suggestion......good luck
 
Hmm,.

Maybe its a painted canvas? Like they do in paintings.The white is the original canvas and maybe at sometime they painted it..

What you have is a canvas with a fabric guard applied (that has deteriorated).


This is very common as canvas needs to breath and once a fabric guard (fabric protector) is placed on the material it can not breath it acts as a sealer and slowly dries the fabric. As this occurs the stencil strength of the material will break down and the fabric guard (sealer) creeps into the weave of the fabric along with dirt, grim and whatever else it's meant to keep off.

Do you have a closer pic? What is the condition of the double bind seams?
