Serving Mills River, NC and nearby towns
Rust stains from sprinklers fed by well water are common in North Carolina, along with tannin stains from leaves and the dark film mildew leaves on concrete.
Red clay soil is common in parts of North Carolina. Rain splashes it onto the bottom of the siding, walls and walkways, and its iron-rich color can stain light surfaces. It usually needs a dedicated clay or rust cleaner rather than pressure alone.

Do you use high pressure for solar panel cleaning?
Solar Panel Cleaning is done with soft brush and purified water (no pressure). Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is solar panel cleaning safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule solar panel cleaning?
Once or twice a year in dusty or pollen-heavy areas. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
