When it comes to revitalizing the look of your driveway or patio, pressure washing is a fantastic solution. However, before you unleash the power of your pressure washer, it’s crucial to know what to spray on concrete to achieve the best results. In this comprehensive guide, we will explore the world of concrete cleaning before pressure washing and discover the top products and techniques to ensure your concrete surfaces look as good as new.

The Importance of Pre-Treatment

Before diving into the nitty-gritty details of concrete cleaning, let’s understand why pre-treatment is crucial. Pre-treatment prepares the surface for pressure washing, making the entire process more effective and efficient. It helps break down stubborn stains, mold, mildew, and grime, ensuring a cleaner and brighter finish.

Selecting the Right Concrete Cleaner for Pressure Washer

One of the essential aspects of concrete pre-treatment is choosing the right cleaner for your pressure washer. Here are some top-rated options:

1. Concrete Power Washing Solutions: These are specially formulated detergents designed to break down tough stains and grime on concrete surfaces. They work by penetrating deep into the pores of the concrete, making it easier to remove dirt and contaminants during pressure washing.

2. Cement Pressure Washer Cleaners: These cleaners are tailored for cement surfaces and are effective in removing cement-based stains and residue. They provide excellent results when used as pre-treatment.

3. Spray-On Concrete Cleaners: These convenient solutions are designed for ease of use. Simply spray the cleaner on the surface, let it sit for a few minutes, and then proceed with pressure washing. They are ideal for quick and efficient cleaning.

Power Washing Concrete – Best Practices

Now that you have your pre-treatment solution ready, it’s time to discuss the best practices for power washing concrete. Here’s a step-by-step guide:

1. Safety First: Always wear protective gear, including safety goggles and gloves, to shield yourself from potential splashes or debris during pressure washing.

2. Clear the Area: Remove any furniture, plants, or objects from the area you plan to clean to prevent damage or obstruction during the process.

3. Begin with Low Pressure: Start with a low-pressure setting on your pressure washer to avoid damaging the concrete. Gradually increase the pressure as needed.

4. Even Pressure and Distance: Maintain a consistent distance from the surface and apply even pressure to ensure uniform cleaning. Avoid holding the nozzle too close to the concrete, as it can cause damage.

5. Overlap Strokes: When moving the pressure washer wand, overlap each stroke slightly to prevent streaks or missed spots.

6. Multiple Passes: For heavily soiled areas, consider making multiple passes with the pressure washer to ensure thorough cleaning.

Cleaning Driveway with Pressure Washer

Your driveway is one of the most frequently used and exposed areas, making it prone to dirt and stains. To clean your driveway effectively, follow these steps:

1. Remove Loose Debris: Begin by sweeping or using a leaf blower to remove loose dirt, leaves, and debris from the driveway’s surface.

2. Apply Pre-Treatment: Spray your chosen concrete cleaner evenly across the driveway, paying extra attention to stained or heavily soiled areas.

3. Let It Sit: Allow the pre-treatment to work its magic by letting it sit for the recommended time, usually 10-15 minutes.

4. Pressure Wash: Use your pressure washer to clean the driveway thoroughly, working from one end to the other. Be patient and ensure you cover every inch of the surface.

Maintaining Your Concrete Surfaces

Once you’ve successfully pressure washed your concrete surfaces, it’s essential to maintain their cleanliness and prevent future stains. Here are some maintenance tips:

1. Regular Cleaning: Schedule regular cleanings to prevent the build-up of dirt and grime. An annual or bi-annual cleaning can keep your concrete looking its best.

2. Sealing: Consider applying a concrete sealer after cleaning. Sealing helps protect the surface from moisture, stains, and UV damage, extending its lifespan.

3. Quick Stain Removal: Promptly address spills and stains by blotting or rinsing them to prevent permanent discoloration.


In the world of concrete cleaning before pressure washing, choosing the right pre-treatment product is essential for achieving impeccable results. Whether you opt for concrete power washing solutions, cement pressure washer cleaners, or spray-on concrete cleaners, following best practices during pressure washing ensures your concrete surfaces will look pristine. Remember that regular maintenance is key to preserving the beauty of your concrete areas. With the right knowledge and tools, you can easily transform your outdoor spaces into a clean and inviting haven. So, gear up, pre-treat, and let the pressure washer work its magic on your concrete surfaces!
