Concrete rust remover

Fertilized this weekend and the neighbors sprinklers came on before I could sweep. Now I have rust stains. I found the below stuff and looks like I just spray, let it sit, and then wash it off. Anything else I should look at? The concrete is basically brand new since the house is new construction.

You want muriatic acid

I've heard muriatic acid can frick concrete up so trying to stay away. Also worried about it getting into my grass. Already tried vinegar and it just lightened it slightly.

Contact Ray immediately, he's been the supervisor with General Concrete Contractors for 20+ years. He will know exactly what to do.

WR Meadows makes a concrete degreaser/cleaner that will clean anything. Even old oil stains. I think it's also pretty safe

Do NOT use muratic acid. It chemically dissolves the bonds of the cement molecules in the top layer of the concrete and you will end up with an accidental exposed aggregate finish.
Oddly, this stuff works wonders in cleaning a concrete surface. As always, try it in a small, inconspicuous area first and then make your own judgement.

The top layer vs the middle or the bottom
Had any chemistry ever?

If you put muratic acid on top of flat, hardened concrete paving, the acid will be in contact and react with the top layer of the concrete.
Not the middle layer or the bottom layer of a hardened concrete driveway.
Had any success in reading comprehension ever?

I had the little rust stains on my driveway and I just ignored it
They either disappeared or i don't notice them anymore
Are they that bothersome to you?

Maybe if you used it without diluting it according to instructions. Diluted to 1:32 (half-cup acid to a gallon of water) will clean without etching the concrete. Can also use citric acid or phosphorous acid in higher concentrations works and is a bit safer to handle.

Idiot
It's pretty simple to understand it's not basic by any means but simple....

Simple.
That was my thought too.
Interesting.

I was trying to etch some concrete before putting epoxy down. Bought some full strength shite, and thought it was diluted. fricking ate through the pump sprayer, smoked yellow for like 30 minutes, and stained the concrete yellow. Burned the hell out of my eyes and I was coughing for two weeks, but the concrete was etched fa sho
