  3. Scrub Brush and Cleaning Agents: Mix your chosen cleaning solution (vinegar and baking soda, dishwashing liquid, or a commercial cleaner) and scrub the surface. Use a nylon brush to avoid damaging the concrete.
  4. Rinse and Mop: After scrubbing, rinse thoroughly with a garden hose. For indoor areas, use a mop to remove excess water.

By having these tools and materials on hand, you’ll be well-prepared to tackle any concrete cleaning task.

Next, we’ll explore how to clean different types of concrete surfaces, from outdoor patios to indoor floors.

How to Clean Different Types of Concrete Surfaces

Cleaning Outdoor Concrete

Patio, Driveway, and Walkway Cleaning

Outdoor concrete surfaces like patios, driveways, and walkways are prone to dirt, algae, and mildew buildup. Here’s how to clean them effectively:

  1. Initial Rinse: Start by rinsing the area with a garden hose to remove loose dirt and debris.
  2. Apply Cleaning Solution: For a natural cleaner, mix equal parts of baking soda and water or vinegar and water in a spray bottle. For stubborn stains, a commercial degreaser can be more effective.
  3. Scrub: Use a stiff brush to scrub the cleaning solution into the concrete. Focus on stained areas and use a bit of elbow grease.
  4. Rinse Again: After scrubbing, rinse the area thoroughly with a garden hose. If you have a power washer, this can make the job quicker and more efficient.

Pro Tip: Test a small area first to ensure the cleaning solution doesn’t damage the surface.

Cleaning Indoor Concrete

Floor and Countertop Cleaning

Indoor concrete surfaces like floors and countertops require a gentler approach to avoid damage:

  1. Dust Mop: Start by dust mopping the floor or wiping down the countertop to remove loose dirt.
  2. Apply Cleaning Solution: For sealed or polished concrete, mix 2 gallons of warm water with 2 teaspoons of dishwashing liquid. For unsealed floors, use a pH-neutral cleaner.
  3. Mop or Wipe: Use a damp mop for floors or a soft cloth for countertops. Avoid excess water to prevent damage.
  4. Rinse and Air Dry: Rinse with clean water and allow the surface to air dry.

Pro Tip: Avoid harsh cleaners like bleach, which can damage the sealant and dull the finish.

Cleaning Sealed, Painted, and Polished Concrete

Sealed Concrete Floors

  1. Sweep or Dust Mop: Remove loose soil with a broom or dust mop.
  2. Mop with Mild Solution: Mix warm water with dishwashing liquid and mop the floor. Avoid harsh cleaners as they can break down the sealant.
  3. Rinse and Air Dry: Rinse with fresh water and let the floor air dry.

Polished Concrete Floors

  1. Dust Mop or Vacuum: Remove dust and debris using a dust mop or vacuum.
  2. Damp Mop with pH-Neutral Cleaner: Use a commercial polished concrete cleaner that is pH-neutral. Most do not require rinsing, but follow the label directions.

Painted Concrete Floors

  1. Dust Mop or Vacuum: Remove loose soil using a dust mop or vacuum.
  2. Damp Mop with Mild Solution: Use a damp mop dipped in a solution of warm water and dishwashing liquid. Rinse with a clean, damp mop and air-dry.

Pro Tip: Painted concrete can have sealed or unsealed finishes. Avoid harsh cleaners to protect the surface.

By following these simple steps, you can keep your concrete surfaces looking their best, whether they’re outside in the elements or inside your home.

Frequently Asked Questions about Concrete Cleaning

What is the best thing to clean concrete with?

When it comes to concrete cleaning, several options are available depending on the type of stain and the condition of the concrete. Here are some of the best methods:

  • Soda: Believe it or not, soda like Coke can be effective for removing grease stains. The carbonic acid, phosphoric acid, and citric acid in soda help break down grease. Pour the soda on the stain, let it sit for 15-30 minutes, then scrub and rinse.

  • Detergent: For smaller grease spills, a strong detergent mixed with water can do wonders. Use a scrub brush and some elbow grease to remove the stain.

  • Vinegar and Baking Soda: This natural cleaner is great if you’re worried about nearby plant life. Mix equal parts water and vinegar (or water and baking soda) in a spray bottle, add a bit of dishwashing liquid, and spray on the concrete. Let it sit for 30 minutes, then scrub and rinse.

  • Concrete Cleaner: Commercial concrete cleaners are formulated to tackle tough stains. Look for products specifically designed for concrete.

  • Bleach: For large areas, mix ¾ cup of liquid bleach with warm water in a bucket and mop the concrete. Let it sit for a few minutes before rinsing.

What do professional concrete cleaners use?

Professionals often use more potent solutions to ensure thorough cleaning:

  • Alkaline Cleaners: These are concentrated soaps that loosen oil and dirt from concrete surfaces. They are especially effective on porous concrete.

  • Oxalic Acid: This is a powerful cleaner used to remove rust and other stubborn stains. Always follow safety guidelines when using strong chemicals like oxalic acid.

How to clean concrete without pressure washing?

If you don’t have a pressure washer, there are still effective ways to clean your concrete:

  • Dish Soap and Hot Water: Mix dish soap with hot water and scrub the area with a nylon brush. This method is great for general cleaning and small stains.

  • Wire Brush: For tougher stains, a wire brush can help. Just be careful not to damage the concrete.

  • Boiling Water: Pour boiling water directly onto grease stains and scrub with a nylon brush. This helps melt and loosen the grease for easier removal.

These methods might require a bit more manual effort, but they can be just as effective as using a pressure washer.

Next, we’ll dive into the best natural and commercial cleaners for concrete.


Regular Maintenance

Keeping your concrete surfaces clean isn’t a one-time task. Regular maintenance is key to preserving the look and longevity of your patios, driveways, and walkways. Simple actions like occasionally rinsing your concrete with clean water and sweeping away debris can prevent dirt and grime from building up over time. This makes your larger cleaning tasks much easier.

Quick Spill Cleanup

Spills happen, but quick cleanup is crucial to avoid stains setting in. For oil and grease spots, use kitty litter or cornstarch immediately to absorb the spill. For other stains, a mixture of baking soda and water or vinegar can work wonders. The quicker you act, the less likely the spill will become a stubborn stain.

High-Quality Sealant

Sealing your concrete can make a world of difference. A high-quality sealant protects your surfaces from weather damage, foot traffic, and stains. It also makes future cleaning tasks much easier. The average cost to seal concrete ranges from $40 for DIY projects to $3,000 for professional services. Investing in a good sealant can save you time and money in the long run.
