Liquid Rust Stain Remover, Pre-mixed, Quickly Removes Rust Stains from Concrete, Vinyl and Other Outdoor Surfaces, No Scrubbing, Safe to Use, 2 Gallons

Fantastic product. I used this in my driveway and on my sidewalks for high mineral/iron Next well water stains. It worked immediately and was extremely easy to use. I just poured some on the affected areas and used a push broom to cover well and then rinsed off with a hose. Goodbye stains!

I ordered this to get the rust iron water stains off my concrete and house. My sprinkler has iron water and leaves rust buildup on the driveway and house over time. So I put this in a pump sprayer and give the concrete a good soak and in just a few minutes the rust is gone! So spray rinse and it’s done. The heavier spots need a second dose and it is slower on plastic pipes but it works great! I’m getting more.

My sprinkler system has iron in it. Lamp posts, vinyl railings, lattice and a garage door were absolutely brown with rust. Iron Out Outdoor made it disappear in seconds. The smell/fumes can be a little overwhelming. Stay up-wind of it.

Used it on vinyl siding to remove rust stains it was awesome also for driveway because of in ground sprinklers overspray caused orange stains

This worked fairly well on iron stains caused by our sprinkler system on our driveway pavers and sidewalk. There are a few places that it didn’t get the stain out but for the most part it worked. It would be nice if they offered a spray attachment to the gallon bottle so you didn’t have to pour it into a separate sprayer. It did wilt the grass on the edges of the driveway but the grass came back within a couple of weeks.

This product is nearly miraculous and I am not one who believes in miracles. We had very bad rust stains from using well water in the sprinkler system. I had previously tried heavy scrubbing with white vinegar and lemon juice to little effect. I just sprayed it on as directed and watched the rust stains disappear. Highly recommended.

Works great! But you have to apply (spray) it more than once if you have dark iron from your irrigation like mine. The whole house was stained from iron from the sprinklers. I’ve tried tons of other products where you have to let it sit or scrub until your arm wants to fall off. This we just sprayed on and like magic dissolved the iron stains in seconds. ONLY DOWN FALL IS IT KILLED OUR GRASS AND PLANTS AROUND IT. The bottle says safe on plants and grass but it wasn’t! If I would have known that I would have covered everything around it with a tarp. Be careful it’s powerful and the fumes are harsh and if you want to save your lawn or plants cover them before you spray.

This stuff is absolutely amazing on rust stains caused by sprinkler systems.. Just be careful not to get it on your grass or plants, it will kill them if too much gets on the vegetation. If a little gets on your grass just spray with some water immediately and you should be fine.
