In most cases, if you have a sprinkler system, you can expect some rust on your concrete. The water that comes out can leave that distinctive rust shadow behind if it gets on concrete. Alternatively, some fertilizers will also have this effect.
Regardless of what causes rust stains on concrete, you need to focus on not only removing it but keeping them gone. You simply need to hire a pressure washing company to come out. Rust cannot simply be sprayed away with a hose because it seeps into the pores of your concrete. It needs to be sprayed at a higher pressure to really penetrate the concrete and flush the rust particles out.
While getting the rust out is as simple as making a phone call, the real issue is preventing it from coming back. In most cases, ensuring proper drainage around your concrete is key to keeping rust stains off your concrete after you have had it cleaned.
