RE: Removing Rust Stains from Concrete

Whink is a very strong acid, really nasty stuff, as acids go. I have some, but don't leave it on. Use it and watch the stain go, then rinse. For concrete try muratic acid, you can get it at most home centers. Acid is what dissolves oxidized iron, which is what those stains are. You could try white vinegar, pour it on and let it set. You may have to do it again, but it's easier to deal with. It's PH is about 4.5, the whink is much lower, so is muratic.

I found a great rust remover, so far it has worked on everything. I have used it on my concrete stairs the wood on my deck and my husbands clothes just to name a few, it is called "Whink" and comes in a brown bottle I usually get it at Walmart. Good luck.
