stucco

Is it stucco? If so, it may contain asbestos if it's an older home. We typically won't ever touch something like that. If it's not asbestos, use a degreaser. If you don't have any, I can give you some. We stock a lot of it, as we use it to clean many things. You can concentrate at whatever level you need, even comes extra strength for really tough jobs.
