How do I remove rust from a concrete step?
By Ron from Princeton, ON
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)
