I have Dan, lots if drivt around here. Apple cider isn't necessary though its pretty easy to clean because it is basically paint.
There is even a drivet cleaner that the drivet company sells.

A VERY mild bleach water mix is what is usually needed. If there are pollutants or oxidation or something like that its a little more comlicated. But 99% of dryvit building/homes are very simple.
YOu can bleach out dryvit or any EIFS type coating with love!!!!!!!!!!! I typically softwash it at about 10- 15%.... I do NOT recommend putting a 30% solution on it at all!!!!!!!!!!
PS, I softwash exclusively...haven't used a pressure washer on a building exterior in years!
Here's some photo proof. I should have let it dwell longer at a lower %, but was unhappy with results and kept making mix hotter & hotter. Remember...dwell time is your friend

About all I do is clean Dryvit and have been an installer for 15 years 15% like said before is what I use and if it does not come as clean as I would like I charge to recoat the surface with a dryvit product called demandit just be upfront and tell them that you may not be able to clean it to like new.
