Muriatic acid, rubber gloves, and a good stiff brush.

I know a product that will guarantee you get the stain out, but it is hard to find if you don't want to purchase it online. It is called "Whink". It absolutely works! It works for rust stains on clothing also. It is a liquid and here is a link if you want to buy it online.

Simply use a 50/50 mix of liquid muriatic acid (for swimming pools) and water and spray it on the area after you have watered it down first. Do not breathe the fumes! Use a hand sprayer. It will eat off the stain in seconds. Rinse it off every 5 seconds or so to see the results. This works on efflorescence on basement walls, too! (04/03/2010)

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 husband's clothes just to name a few. It is called "Whink" and comes in a brown bottle. I usually get it at Walmart. Good luck.

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. (06/18/2009)

We purchased a new fire pit for the patio. We never used it but the wrought iron still left rust spots on our patio. Could anyone please tell us how can you clean rust from concrete without damaging the concrete?

Try Barkeeper's Friend, it is usually found along the cleaning cleansers like Comet and such. Read the directions on how to remove rust stains from concrete. (01/08/2008)
