We did a "prep for paint" house washing this past weekend, and I need to ask a question.
There was a black stain around the top 2-3 feet just under the roofline of the house. I thought it might be mildew, but we hit it with strong bleach and detergent mixture and nothing happened. We did wash a ton of dirt off the house, but the black stain is still there. We tried brushing straight chemical and even tried brushing a small hidden section with full strength concrete cleaner. Nothing happened.
The stucco is approximately 60 years old. We were told that the soffit was installed about 5 years ago, and the stains were there before the soffit was installed.
When we cleaned the soffit, more black dirt came out through the perforations.
Anyone know what the black stain is? Could it just be 60 year old dirt that will never come off?
Thanks in advance.
