What Should I Spray Before Pressure Washing?

If you’re getting ready to pressure wash your home or outdoor surfaces, it’s important to prep them properly by spraying the right solutions before you start. This not only helps to remove stubborn dirt and grime more effectively but also ensures a more thorough clean overall. Here’s a detailed guide on what you should spray before pressure washing to achieve the best results.

Why Should You Spray Before Pressure Washing?

Before we dive into what solutions you should use before pressure washing, let’s talk about why this step is important. Spraying surfaces with the right cleaning solution beforehand helps to break down dirt, grime, mold, and mildew, making it easier for the pressure washer to remove these contaminants. This pre-treatment step can also prevent potential damage to the surface being cleaned, as the pressure washer won’t need to work as hard to remove tough stains.

Precautions Before Spraying

Before you start spraying any solutions on the surfaces you plan to clean with a pressure washer, there are a few precautions you need to keep in mind. Make sure to:

Wear protective gear such as gloves, goggles, and boots to protect yourself from the cleaning solution.
Test the cleaning solution on a small, inconspicuous area first to ensure it doesn’t cause any damage.
Read the manufacturer’s instructions on the cleaning solution to ensure proper usage and dilution ratios.

Homemade vs. Store-Bought Solutions

When it comes to pre-treating surfaces before pressure washing, you have the option of using either homemade solutions or store-bought ones. Homemade solutions are usually more cost-effective and environmentally friendly, while store-bought solutions are specifically formulated for pressure washing and may offer stronger cleaning power.

Homemade Cleaning Solutions

If you prefer using homemade solutions, here are a few effective options you can try before pressure washing:

Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Vinegar is a natural disinfectant and can help break down dirt and grime on surfaces.
Baking Soda Paste: Mix baking soda with water to create a thick paste. Apply the paste to stubborn stains and let it sit for a few minutes before rinsing off.
Citrus Cleaner: Mix equal parts water and lemon juice in a spray bottle. Lemon juice has natural grease-cutting properties, making it effective for pre-treating surfaces.

Store-Bought Cleaning Solutions

If you prefer to use store-bought solutions for pre-treating surfaces before pressure washing, there are several options available on the market. Look for solutions that are specifically designed for pressure washing and suitable for the surfaces you plan to clean. Some popular store-bought cleaning solutions include:

Pressure Washer Detergents: These detergents are formulated to work with pressure washers and can effectively remove dirt, grime, and mildew.
Mold and Mildew Cleaners: If you’re dealing with mold and mildew on your surfaces, opt for a cleaner that specifically targets these contaminants.
Degreasers: For surfaces with heavy grease and oil stains, a degreaser can help break down these substances before pressure washing.

What Surfaces Should You Spray Before Pressure Washing?

Not all surfaces require pre-treatment before pressure washing. However, for tougher stains and contaminants, it’s recommended to spray the following surfaces before using a pressure washer:

Siding: If your home’s siding has accumulated dirt, mold, or mildew, pre-treating it with a cleaning solution can help remove these contaminants more effectively.
Driveways and Walkways: Concrete driveways and walkways often have oil stains and dirt buildup that can benefit from pre-treatment before pressure washing.
Decking and Fences: Wooden decking and fences may require a pre-treatment to remove mold, mildew, and stubborn stains before pressure washing.
Brick and Stone Surfaces: Porous surfaces like brick and stone can benefit from pre-treatment to lift dirt and grime out of the crevices.

How to Spray Cleaning Solutions Before Pressure Washing

Once you’ve selected the appropriate cleaning solution for your surfaces, it’s time to spray them before pressure washing. Here’s a step-by-step guide on how to pre-treat surfaces effectively:

Prepare the Cleaning Solution: Mix the cleaning solution according to the manufacturer’s instructions or the homemade recipe.
Apply the Solution: Use a pump sprayer or a spray bottle to apply the cleaning solution evenly onto the surface. Start from the bottom and work your way up to prevent streaking.
Let it Sit: Allow the cleaning solution to dwell on the surface for a few minutes to break down the dirt and grime effectively.
Scrub if Necessary: For stubborn stains, you may need to scrub the surface lightly with a soft brush to help lift the contaminants.
Rinse: Once the cleaning solution has had time to work, rinse the surface thoroughly with clean water before pressure washing.

Tips for Effective Pre-Treatment

To ensure effective pre-treatment before pressure washing, keep the following tips in mind:

Use the Right Dilution: Always follow the manufacturer’s instructions for diluting store-bought cleaning solutions. Using a solution that is too concentrated can damage the surface.
Work in Sections: Divide larger surfaces into manageable sections and spray one section at a time to ensure even coverage.
Avoid Direct Sunlight: Try to pre-treat surfaces in the shade or during cooler hours of the day to prevent the cleaning solution from drying too quickly.
Safety First: Wear protective gear and ensure proper ventilation when working with cleaning solutions to protect yourself.

Conclusion

Pre-treating surfaces before pressure washing is a crucial step to achieving a thorough and effective clean. By selecting the right cleaning solution, applying it correctly, and following the necessary precautions, you can ensure that your pressure washing job yields impressive results. Remember to always test the cleaning solution on a small area first and consult the manufacturer’s instructions for the best practices. Happy cleaning!
