Use concrete cleaner . Just test some spot before as with any cleaner. Dryvit is a concrete finish. I was cleaning dryvit buildings with my father over 20 years ago using very simple chemicals . If not careful you will learn fast to not use pressure on it. I saw first building ever with dryvit finish ... it's over 38 years old and it looks like new !
Good luck
