I just did my first black and white awning today.
Pretty nasty, picture doesn’t show how bad it was. I did the usual bleach/scrub/bleach/rinse procedure and frankly I’m disappointed.
The dead mildew turned brown as usual but made the white stripes a light tan color. I talked with the customer and she said it’s a vast improvement and go ahead with the rest but I’m not happy. Sorry the pics are reversed, dirty one is on the bottom.
What more can I do? Will the sun eventually bleach it out?
I think it looks very good. Sometimes we can not fix what a homeowner has neglected for years.
Idk Brock it looks perfect in your picture. 
We’ve done quite a few awnings 4.5% bleach and rinse and repeat as needed lol thats all we can do.
Customers have always been happy
Looks like you need a little stronger mix. What % did you use? Doesn’t look to bad in pic though.
I’ll try and get a better ‘after’ pic today, need to go back for the window cleaning.
I’m with everyone else on this one…I’d consider that for a solid before/after promo pic for awnings if the angles were better 
Looks pretty good to me….I wouldn’t worry about it.
I’m doing about 20 awnings right now and I bought Winsol deep clean for them. It helps to clean them and protect them afterwards. (With a hot sh mix) I feel that it’s an upgrade over regular surfactant. But I’ve found that my 1000 psi tip (65-20) is what’s needed to really get them clean. You have to be careful though because the material needs to be in good condition otherwise it may tear.
I’ve cleaned a couple with SH, but a couple local guys I know have used this with great results.
