I know you have to be careful when pressure washing stucco but i have a light colored stucco (khaki color) that has some red clay stain from water dripping off roof. Has been on there about 2 months. Tried the ZEP generaly pressure washing concentrate today and it took the clay off but still is not clean. Should i try the cleaner that is for driveways or concrete?
