Nature of Concrete Stains

Stains on concrete aren’t just surface-level issues; they seep deep into the pores, clinging onto the material. This can make them particularly stubborn to remove, especially if they’ve been sitting for a while. The nature of the stain—whether it’s oil-based, organic, or rust—can also affect how it interacts with the concrete, making some stains more challenging to clean than others.

Factors Contributing to Stains

Several factors contribute to the formation of stains on concrete. In Des Moines, the changing seasons bring a variety of staining agents. The environment, combined with everyday accidents like oil drips from cars or paint spills, means that concrete surfaces are constantly under siege from potential staining agents.


Summer barbecues can leave grease and food stains, while fall leaves can leave tannin marks and moisture, leading to mildew. Winter snow and ice, mixed with road salts and melting agents, can create a perfect storm for rust and salt stains.

Cleaning Supplies and Techniques

Equipping yourself with the right tools and knowledge is the first step towards effectively removing concrete stains.

Essential Supplies

A successful cleaning arsenal includes:

  • Protective gear: Always wear gloves and goggles to protect yourself from harsh chemicals.
  • Brushes: A stiff brush or broom is crucial for scrubbing the stain out of the concrete.
  • Cleaning agents: Depending on the stain, you may need anything from mild dish soap to stronger chemical cleaners.
  • Water: A hose or bucket of water is essential for rinsing away cleaning solutions and loosened debris.

Choosing the Right Technique

The technique you choose should be tailored to the type of stain you’re dealing with. Light stains might come out with a simple mixture of soap and water, but more stubborn stains like oil or rust may require a more aggressive approach with specialized cleaners.

Eco-Friendly Options

For those concerned about the environmental impact, there are plenty of eco-friendly solutions. Vinegar, for example, is great for mild stains and doesn’t harm the surrounding grass or plants. Baking soda can also be used to clean without introducing harsh chemicals into your environment.

Removing Stains

Tackling specific stains requires a targeted approach. Here’s how to address each type effectively:

Bird Droppings

Bird droppings are acidic and can etch concrete over time. Start by soaking the area with water to loosen the droppings. Next, apply a mixture of soap and water, scrubbing gently with a brush. For stubborn areas, a diluted vinegar solution can help break down the acidity. Rinse thoroughly with water when done.

Dirt and Foliage

Dirt and decomposing leaves can leave tannin stains on concrete. Sweep away any loose debris first. Mix soap with water and scrub the stained area vigorously. For deep stains, a pressure washer set on a low setting can remove embedded dirt without damaging the concrete. Rinse well after cleaning.

Food Grease

Grease stains are common around grills and eating areas. Absorb fresh spills with cornstarch or kitty litter. For dried stains, apply a degreaser or a solution of dish soap and water. Let it sit to break down the grease, then scrub with a stiff brush. Rinse thoroughly with hot water.

Mildew and Mold

Shady, moist areas are prone to mildew and mold. Protect yourself with gloves and a mask, then apply a solution of one part bleach to three parts water. Allow it to sit for a few minutes to kill the spores, then scrub it with a stiff brush. Rinse the area well to remove all traces of bleach.

Oil Stains

Oil penetrates deeply into concrete. Apply a degreaser or create a paste with baking soda and water for natural absorption. Cover the stain, let it sit to draw out the oil, then scrub off. Repeat if necessary. Rinse thoroughly with water.


Remove fresh paint spills by blotting, not rubbing. For dried paint, apply a paint stripper designed for concrete. Follow the product’s instructions carefully, then scrub the area with a stiff brush. Rinse the area well to remove all chemical residues.

Pet Stains

Pet accidents can leave odors and stains. Clean the area with a solution of equal parts water and vinegar to neutralize odors. For tougher stains or persistent smells, consider using an enzymatic cleaner specifically designed for pet stains. Scrub gently and rinse well.

Rust Stains

Rust stains require a specific approach due to their chemical composition. Use a commercial rust remover suitable for concrete, following the manufacturer’s instructions. These products typically require application, a set time for the chemical to react, and then scrubbing and rinsing.

Tire Marks

Tire marks are mostly superficial but can be unsightly. Apply a degreaser to the area, let it sit to break down the rubber, then scrub with a stiff brush. A pressure washer can also be effective for removing tire marks from concrete. Rinse thoroughly after cleaning.


Water stains, often from mineral deposits, can be cleaned with vinegar. Dilute white vinegar with water, spray onto the stains, let it sit to dissolve the minerals, then scrub and rinse. For stubborn deposits, a commercial concrete cleaner may be necessary.

How To Prevent Stains

Prevention is key to maintaining the appearance of your concrete surfaces over time.


Applying a concrete sealant can provide a barrier that prevents stains from penetrating the surface. Choose a sealant appropriate for your concrete type and apply it according to the manufacturer’s instructions. This can make future cleaning efforts much easier.

Regular Maintenance

Regularly sweeping and washing your concrete can prevent the buildup of stain-causing substances. Address spills as soon as they happen to prevent them from setting in. A routine cleaning schedule can go a long way in keeping your concrete pristine.

Protective Measures

Take proactive steps to minimize staining opportunities:

  • Place grill mats under BBQs to catch grease.
  • Use drip pans under vehicles to catch oil.
  • Avoid using deicing salts which can lead to salt stains and concrete damage.
  • Place mats or rugs in high-traffic areas to reduce wear and tear.

These simple yet effective strategies not only preserve the look of your concrete but also extend its lifespan, saving you time and money in the long run. Embrace these practices to keep your concrete surfaces looking their best, ensuring they remain a point of pride in your home or business.


Maintaining clean concrete surfaces doesn’t have to be daunting. With the right knowledge, tools, and preventative measures, you can tackle any stain—in your driveway, patio, or indoor—and keep your concrete looking its best. Remember, the key to effective stain removal is prompt action and regular maintenance. By following these guidelines, you’ll ensure your concrete surfaces remain beautiful and functional for years to come.

How do you remove dried concrete stains?

To remove dried concrete stains, start by soaking the area with water to loosen the stain.
