Pressure Washing vs Soft Washing: Which is the Best Option for Cleaning Your Home’s Exterior?

Pressure Wash Cleaning the exterior of your home is an essential task that helps maintain its appearance and prolong its lifespan. Two popular methods for cleaning the exterior are pressure washing and soft washing. While both techniques are effective, they have distinct differences and are best suited for different surfaces. In this article, we will explore the differences between pressure washing and soft washing and help you determine which method is better for your home.

Understanding the Difference: Pressure Washing vs Soft Washing

Let’s quickly run through the main differences between the two methods:

Pressure Washing

Pressure washing is a powerful cleaning method that utilizes high-pressure water to remove dirt, grime, mold, and other contaminants from various surfaces. This technique involves using a pressure washer, which can release water at a pressure of 2,000 to 3,000 pounds per square inch (PSI). The force generated by the high-pressure water effectively removes stubborn stains and debris.

Soft Washing

On the other hand, soft washing is a gentle and more delicate cleaning method that utilizes low-pressure water combined with specialized cleaning solutions to clean surfaces. Unlike pressure washing, which relies mainly on the force of water, soft washing involves the use of biodegradable chemicals to break down and remove contaminants. The low-pressure water spray is gentle on the surfaces, making it suitable for more delicate materials.

When to Use Pressure Washing for Exterior House Cleaning

Pressure washing is highly effective for cleaning tough and hard surfaces such as brick walls, driveways, garage floors, paved patios, pathways, and sidewalks. The high-pressure water can easily blast away dirt, grime, mold, and even paint without causing damage to concrete surfaces. It’s an excellent choice for surfaces that can withstand the force of the water.

Here are some situations where pressure washing is the preferred option:

Concrete Surfaces:

Pressure washing is ideal for cleaning concrete surfaces such as driveways and sidewalks. The high-pressure water can effectively remove oil stains, dirt, and grime, restoring the surface’s appearance.

Removing Paint:

Pressure washing is an effective method for removing old paint from surfaces before repainting. The force of the water can strip away loose or peeling paint, preparing the surface for a fresh coat.

Tough Stains:

If you have stubborn stains or contaminants on your exterior surfaces, pressure washing can help. The high-pressure water can break down and remove deep-seated dirt, mold, and mildew.

While pressure washing is highly effective, it’s important to use caution and follow safety guidelines. The high pressure can cause damage to surfaces if not used correctly. It’s recommended to hire a professional pressure washing service for the best results and to avoid accidents.

When to Use Soft Washing for Exterior House Cleaning

Soft washing is a more delicate and gentle cleaning method that is suitable for surfaces that cannot withstand the force of high-pressure water. This method is effective in removing biological elements such as algae, mold, and mildew without causing damage. Soft washing is particularly useful for the following surfaces:

Siding and Decking:

Soft washing is ideal for cleaning materials such as stucco, wood decking, wood siding, wood fencing, painted wood, and cedar shake. These surfaces are more vulnerable and can be damaged by the force of pressure washing.

Delicate Materials:

If you have delicate materials or surfaces that require a more gentle approach, soft washing is the better option. It can effectively clean without causing any harm or damage.

Detailed Cleaning:

Soft washing is excellent for cleaning in between crevices and hard-to-reach areas. The specialized cleaning solutions used in soft washing can penetrate and remove contaminants from even the smallest spaces, resulting in a thorough and long-lasting clean.

Soft washing also offers environmental benefits as the biodegradable chemicals used are safe for your family, pets, and plants. It is a more eco-friendly option compared to pressure washing, which relies solely on water pressure.

Choosing Between Pressure Washing and Soft Washing

When deciding between pressure washing and soft washing for your exterior house cleaning needs, consider the following factors:

Surface Type

Determine the type of surface you want to clean. If it is a hard and durable surface, pressure washing may be the better option. For delicate materials or surfaces that require a more gentle approach, soft washing is the preferable choice.

Cleaning Intensity

Consider the level of cleaning intensity required. If you have tough stains or deeply embedded dirt and grime, pressure washing can provide the necessary force to remove them. However, if you are dealing with biological elements or require detailed cleaning, soft washing is the more suitable method.

Potential Damage

Take into account the potential damage that can occur with each method. Pressure washing, if not used correctly, can cause damage to surfaces, paint, window seals, and landscaping. Soft washing, on the other hand, is a safer option that minimizes the risk of damage.

Professional Assistance

If you are unsure about which method to choose or lack experience with pressure or soft washing, it is recommended to seek professional assistance. A professional pressure washing service can assess your specific needs and provide expert advice on the best cleaning method for your home’s exterior.


Pressure washing and soft washing are both effective methods for cleaning your home’s exterior. The choice between the two depends on the type of surface, cleaning intensity, and potential for damage. Pressure washing is suitable for tough and hard surfaces, while soft washing is better for delicate materials and detailed cleaning. Consider these factors and, if in doubt, consult a professional to ensure the best results for your home.
