Where it comes from
- Sprinklers on well water or old iron pipe leave orange fans on walks, foundations, and siding.
- Some lawn fertilizers have iron in them. Pellets left on the concrete leave small orange dots.
- Metal furniture, planters, and grills leave rings.
Why pressure won't remove it
Rust is in the concrete, not sitting on top. Blasting it only wears down the surface and the stain stays. It takes a rust remover made for that surface.
How we treat it
We apply the remover with a pump sprayer or brush it onto spots, let it work, and rinse with plenty of water. On sprinkler stains we treat the whole stained area so it doesn't come out patchy. Plants get wet down first and rinsed after, and we keep it off glass and metal fixtures.
Keeping it from coming back
If the sprinklers caused it, they'll cause it again. Adjust the heads so they don't hit concrete or the house, or put an iron filter or treatment on the irrigation line. Sealing the concrete after the treatment also helps new rust rinse off before it sets in.
Price
Most rust jobs run $129 to $349, based on how many stained areas there are and how big they are. Sprinkler fans along the whole front of a house are at the high end.
Rust questions
Is the treatment safe for my lawn?
Yes, with the way we use it. We wet the grass and beds first and rinse them well after.
Can you get rust off stucco or siding?
Often, yes. We use a milder product and test a small spot first.
How fast does it work?
Most rust fades within a few minutes of the treatment going on. Old, heavy stains sometimes need a second application.
