Are you getting ready to give your house a fresh new look with a thorough pressure washing? Before you break out the equipment, it’s essential to prepare your home’s exterior by spraying it with the right solutions to ensure a safe and effective cleaning process. But what should you spray your house with before pressure washing? In this article, we’ll explore the best options to remove dirt, grime, and stubborn stains, leaving your home looking like new.
The Importance of Pre-Treating Your Home’s Exterior
Before you start pressure washing, it’s crucial to understand the importance of pre-treating your home’s exterior. Pressure washing alone can sometimes push dirt and debris further into the surface, making it difficult to remove. Additionally, using the wrong cleaning solution or not preparing the surface properly can damage your home’s exterior, leading to costly repairs.
By pre-treating your home’s exterior, you can:
- Loosen dirt and grime, making it easier to remove
- Break down stubborn stains and mildew
- Prevent damage to your home’s exterior by neutralizing alkaline substances
- Save time and energy during the pressure washing process
Common Pre-Treatment Options for Pressure Washing
Now that you understand the importance of pre-treating your home’s exterior, let’s explore the common pre-treatment options available:
Bleach Solutions
Bleach is a popular choice for pre-treating exterior surfaces due to its ability to effectively kill mold and mildew. However, it’s essential to use a diluted bleach solution to avoid damaging your home’s exterior. A typical bleach solution consists of one part bleach to three parts water. Be cautious when using bleach, as it can:
- Damage or discolor certain types of siding, such as vinyl or aluminum
- Dry out and crack wood surfaces
- Kill plants and grass
Sodium Hydroxide (NaOH) Solutions
Sodium hydroxide, also known as caustic soda, is a strong alkaline substance that can effectively break down dirt and grime. However, it’s essential to use protective gear when handling NaOH solutions, as they can cause skin and eye irritation. A typical NaOH solution consists of one part NaOH to four parts water. Be cautious when using NaOH solutions, as they can:
- Damage skin and eyes if not handled properly
- React with certain types of siding, causing damage or discoloration
- Neutralize the effectiveness of some pressure washing detergents
Mild Detergents
Mild detergents are a safer and more environmentally friendly option for pre-treating your home’s exterior. They’re biodegradable, non-toxic, and gentle on surfaces. Look for detergents specifically designed for pressure washing, as they’re usually formulated to work effectively in high-pressure environments. A typical mild detergent solution consists of one part detergent to four parts water.
Oxygen Bleach Solutions
Oxygen bleach, such as OxiClean, is a safer and more environmentally friendly alternative to chlorine bleach. It’s effective at breaking down dirt and grime without damaging your home’s exterior. A typical oxygen bleach solution consists of one part oxygen bleach to four parts water.
Best Practices for Pre-Treating Your Home’s Exterior
Now that you’ve chosen the right pre-treatment solution, it’s essential to follow best practices to ensure a safe and effective cleaning process:
Always Read the Label
Before using any pre-treatment solution, read the label carefully to ensure you’re using the correct concentration and application instructions.
Wear Protective Gear
Always wear protective gear, such as gloves, goggles, and a mask, when handling pre-treatment solutions to avoid skin and eye irritation.
Test a Small Area
Before applying the pre-treatment solution to your entire home’s exterior, test it on a small, inconspicuous area to ensure it doesn’t damage the surface.
Apply the Solution Correctly
Use a low-pressure sprayer or a soft-bristled brush to apply the pre-treatment solution evenly to your home’s exterior. Avoid using high-pressure sprayers, as they can damage surfaces.
Let it Sit
Allow the pre-treatment solution to sit on the surface for 10-15 minutes to allow it to penetrate and break down dirt and grime.
What to Avoid When Pre-Treating Your Home’s Exterior
When pre-treating your home’s exterior, there are certain things to avoid to ensure a safe and effective cleaning process:
Avoid Using Harsh Chemicals
Avoid using harsh chemicals, such as acid-based cleaners or strong solvents, as they can damage your home’s exterior or harm the environment.
Don’t Use High-Pressure Sprayers
Avoid using high-pressure sprayers when applying pre-treatment solutions, as they can damage surfaces or force dirt and debris further into the surface.
Never Mix Solutions
Never mix different pre-treatment solutions, as they can react with each other and cause damage to your home’s exterior or harm the environment.
Don’t Forget to Rinse
Make sure to rinse your home’s exterior thoroughly after applying the pre-treatment solution to remove any residue and prevent damage.
Conclusion
Pre-treating your home’s exterior before pressure washing is a crucial step in achieving a sparkling clean home. By choosing the right pre-treatment solution and following best practices, you can loosen dirt and grime, break down stubborn stains, and prevent damage to your home’s exterior. Remember to always read the label, wear protective gear, test a small area, apply the solution correctly, and let it sit before rinsing.

What is the importance of spraying before pressure washing?
Spraying before pressure washing is a crucial step in preparing your home’s exterior for a sparkling clean finish. It helps to loosen dirt, grime, and other substances that can be stubborn and difficult to remove with pressure washing alone. By spraying a solution beforehand, you can break down these substances and make the pressure washing process more effective.
Moreover, spraying before pressure washing can also help to prevent damage to your home’s exterior surfaces. For instance, if you are dealing with stubborn stains or mildew, using a solution that is specifically designed to target these issues can help to lift them away before you begin pressure washing. This can help to prevent scratching or damaging your home’s surfaces, which can occur if you try to remove these substances using high-pressure water alone.
What types of surfaces can I spray before pressure washing?
You can spray before pressure washing a variety of surfaces, including siding, decks, patios, driveways, and sidewalks. In fact, spraying before pressure washing is especially important for surfaces that are prone to staining or mildew, such as wood decks or fences. By spraying a solution that is specifically designed for these surfaces, you can help to lift away dirt and grime and leave them looking like new.
It’s also important to note that you should only use a solution that is specifically designed for the surface you are cleaning. For instance, if you are cleaning a wood deck, you should use a wood deck cleaner, rather than a solution that is designed for siding or concrete. Using the wrong solution can damage the surface or leave behind residue, which can affect the overall appearance of your home’s exterior.
What types of solutions can I use to spray before pressure washing?
There are a variety of solutions that you can use to spray before pressure washing, depending on the type of surface you are cleaning and the type of dirt or grime you are dealing with. For instance, you can use a general-purpose cleaner, a degreaser, or a solution that is specifically designed to target mildew or mold. You can also use a bleach solution, but be sure to exercise caution when using bleach, as it can damage certain surfaces or discolor them.
It’s also important to note that you should always read the label and follow the instructions when using any type of cleaning solution. Make sure you are using the solution in a well-ventilated area and wearing protective gear, such as gloves and eyewear. Additionally, be sure to test the solution on a small, inconspicuous area first to ensure that it doesn’t damage the surface you are cleaning.
How do I apply the solution before pressure washing?
To apply the solution before pressure washing, simply use a pump-up sprayer or a garden sprayer to apply the solution to the surface. Be sure to hold the sprayer about 6-8 inches away from the surface and move it back and forth to ensure even coverage. You can also use a brush or broom to apply the solution, especially if you are cleaning a surface with a lot of crevices or grooves.
It’s also important to make sure you apply the solution in a consistent manner, so that the entire surface is evenly coated. This will help to ensure that the solution has a chance to penetrate and lift away dirt and grime, leaving your surface looking clean and sparkling.
How long should I let the solution sit before pressure washing?
The amount of time you should let the solution sit before pressure washing will depend on the type of solution you are using and the type of surface you are cleaning. As a general rule, you should let the solution sit for at least 10-15 minutes to allow it to penetrate and lift away dirt and grime. However, you may need to let it sit for up to 30 minutes or more, depending on the specific instructions on the label.
It’s also important to make sure you Rinse the surface thoroughly with water after the solution has had a chance to sit. This will help to remove any remaining dirt and grime, as well as any residue from the cleaning solution. Be sure to use a wide fan tip on your pressure washer to distribute the water evenly and avoid damaging the surface.
Can I use a pressure washer to apply the solution?
While it may be tempting to use a pressure washer to apply the solution, it’s generally not recommended. Pressure washers are designed to provide high-pressure water streams, which can be too intense for applying cleaning solutions. Using a pressure washer to apply the solution can cause the solution to be blown away from the surface, reducing its effectiveness.
Instead, use a pump-up sprayer or a garden sprayer to apply the solution. These types of sprayers provide a gentle, consistent stream of solution that can be easily controlled. By applying the solution in this way, you can ensure that it has a chance to penetrate and lift away dirt and grime, leaving your surface looking clean and sparkling.
Are there any safety precautions I should take when spraying before pressure washing?
Yes, there are several safety precautions you should take when spraying before pressure washing. First and foremost, make sure you wear protective gear, such as gloves, eyewear, and a mask. This will help to protect you from any harsh chemicals or debris that may be present on the surface.
You should also make sure you are spraying in a well-ventilated area, away from any open windows or doors. This will help to prevent the solution from being blown back onto you or into your home. Additionally, be sure to rinse the surface thoroughly with water after applying the solution, to remove any remaining dirt and grime.
