The secret to rust stain removal for concrete is using the right method, not the most pressure. In Boulder, CO, we match the cleaner and pressure to the surface so it comes out clean without damage. For concrete, that means pressure wash with a surface cleaner.
Method and pressure
Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.
Caring for concrete
Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.
Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.
How often: Every year, or every 6 months in shaded, damp spots.

Do you use high pressure for rust stain removal for concrete?
For concrete: usually 2,500-3,500 PSI with a rotary surface cleaner for even results. What we avoid: holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete. We keep the pressure even and controlled, with the right tools for the surface.
Is rust stain removal for concrete 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 rust stain removal for concrete?
Every year, or every 6 months in shaded, damp spots. 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, and sealers and stains need dry weather to cure. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
