How to Remove Rust Stains from Concrete

June 15, 2020

Rust stains can form just about anywhere, including your concrete garage floor, patio and walkways. For anyone who wants their property to look neat and clean, this can be distressing. After all, curb appeal is key when it comes to your home’s or business’s resale value. Even if the rust stains formed through no fault of your own, visitors and customers will get the impression that the property has been neglected.

There are a few different ways to remove rust stains from concrete, including Magica® Rust Removers. Read on to learn why rust forms on concrete and how to get rid of it.

Why rust forms on concrete

As you probably know, rust forms when iron and oxygen react in the presence of water, whether that’s in the air or on a surface. You might assume that concrete doesn’t contain iron, so if you’re puzzled about how rust stains can form on your driveway, you’re not alone.

There are several different possibilities for how those rust stains got on your concrete surface. First, the concrete itself could contain iron particles as a byproduct of the manufacturing process. (This isn’t common, however.)

The more likely culprit is that iron objects came into contact with water while laying on or after being embedded in your concrete. For example, iron rebar, which is used to reinforce concrete structures, can rust. If the rebar is too close to the surface, water will penetrate and cause the rebar to rust. As it rusts, it will expand and push pieces of the concrete out. This further allows water penetration. It is exacerbated by using salt to deice concrete roadways.

To prevent rust stains, keep metal objects off your concrete floors and walls, especially outdoors and in wet, humid conditions.

Use these rust removal options

Here are some possible options to remove rust from concrete surfaces:

  • Lemon juice or vinegar: Pour lemon juice or vinegar directly onto the stain, and use a stiff brush to scrub the stain away. Rinse thoroughly with cool water. Repeat as needed.
  • Laundry detergent or baking soda: You can form a paste with liquid laundry detergent and baking soda. Apply to the stain and let sit for an hour, making sure that it stays damp. (Otherwise, it will harden instead of penetrating the concrete.) Then simply scrub away with a stiff brush and rinse thoroughly.
  • Magica® Rust Removers: For the easiest and most effective rust removal process, use Magica® Rust Removers.
