Do you think just pressure would work on this? I’ve never worked with this type of surface before.
Also how much would you charge for something like this?
Thanks
Do not use pressure on stucco. You’ll more than likely damage it and especially near the top or bottom where it’s already coming lose. Hit it with sh, let dwell, and rinse. I’d use a 12v and start at around 2%-3%. You might have to go a little stronger where it’s really black or just hit it a few times. Be sure to wet down the windows first and rinse them well.

3% SH as said above
Like said above 2-4% using a proportioning system. You’ll also want to invest into some liquid sodium thiosulfate to rinse the windows with. That will neutralize your chemical that surface.
Try to have one person go ahead of you to soak the ground and vegetation. Then rinse those same areas behind you, while also keeping the windows wet.
Remember dryvit is a painted surface so some areas may stain, especially where the roof shingles meet .
Don’t waste your money… just don’t let your soap dry on the windows

Cool thanks guys!
Little late here but some other things to remember about dryvit. It looks like stucco but what it really is is a super thin layer of color tinted material (1/32” thick) applied over styrofoam. What these guys above said is spot on just be real careful as it is extra fragile. If you mess up the material and or color you could probably get a close paint match but the sheen will not match. I installed a Verizon sign in Vallejo and despite me telling them 6 times that painting wouldn’t work and they needed to pay to have the whole fascia re-skinned they insisted on the paint. I used 8 gallons on 200 square feet to finally get it to look decent as it just sucked it all up but it still didn’t look great.
