Fertilizer Rust Stains on Concrete

[PowerWashPros]

We live in a new subdivision and a few of the houses up the street dont have the sod put in the front yard yet, they have tilled the ground and put the fertilizer in for the new sod though. Well we got a crap load of rain today and it washed the mud down the street, after we washed the dirt from the sidewalks we noticed that they are completly covered in rust spots. Can anyone recomend a chemical or procedure to remove this from the concrete?

rust

read fast they will remove this post applied straight with pump sprayer just a light covering enough to just get wet then rinse if it is light maybe dillute may have to do whole drive. get a resporator. at edges of grass it will burn grass but it will come out.

You have no respect for this boards rules which it SHOWED means you have no respect for any type rules.No hard feelings from here but sometimes business is business and we're not fooling around anymore.

Oxalic acid will remove the rust stains.It's fast and effective and you can buy it in bulk.2 pounds to 5 gallons of water and xjet it.We normally don't rinse from concrete,but do if we use it to nuetralize.brighten a deck.

I didn't think oxalic worked on fertilzer. I thought most fertilzers where Iron based and would not be affected by oxalic
