Removing Rust Stains From Concrete

Rust can be one of the hardest of all stains to remove, especially if the stain is on a porous substrate such as concrete. These stains often originate from a rusty piece of metal stored on the concrete or even from fertilizer containing iron. Removal of rust stains from concrete is best achieved by dissolving the rust with a chemical that unlike muriatic acid, which is often used to clean concrete, does not etch the concrete. The best product that I have found for this task is called Iron Out. It comes as a granular powder and can be purchased in most home improvement stores. Look for it in the plumbing section next to chemical drain cleaners such as Drano. If you follow the instructions you should be able to eliminate your rust stains without damaging your concrete.  Discover and share home improvement knowledge at www.HomebuiltHowTo.com.
