Soft Washing vs. Pressure Washing: Understanding the Key Differences

When it comes to cleaning and maintaining the exterior surfaces of our homes or commercial properties, two popular methods come to mind: soft washing and pressure washing. While both techniques aim to enhance the appearance and longevity of surfaces, they differ in methodology, water pressure, and applications. In this article, we will explore the fundamental distinctions between soft washing and pressure washing, enabling you to make an informed decision based on your specific cleaning needs.

1. Methodology:

Soft Washing: Soft washing involves the use of specialized cleaning solutions and low-pressure water application to remove dirt, grime, mold, mildew, algae, and other contaminants from various surfaces. The process typically employs a specialized, high volume, low pressure pump to apply the cleaning solution gently. It allows the solution to penetrate deep into the surface, effectively killing the underlying organisms (moss, mildew, and algae) without causing any damage.

Pressure Washing: Pressure washing employs the use of high-pressure water to remove stubborn stains, dirt, and debris from surfaces. It relies on a powerful pump that sprays water at significantly higher pressure levels. The forceful water stream dislodges and blasts away accumulated dirt, mold, mildew, loose paint, and other contaminants.

2. Water Pressure:

Soft Washing: Soft washing employs low-pressure water application, typically around 1000 psi (pounds per square inch) or lower. The primary focus is on the chemical solution and its ability to break down and eliminate contaminants effectively. The low-pressure stream ensures the safety of delicate surfaces, such as siding, roofs, and painted surfaces, preventing any potential damage that high-pressure water might cause.

Pressure Washing: Pressure washing operates at higher water pressure, often ranging from 1500 psi to 4000 psi or higher, depending on the equipment used. The forceful water stream effectively removes stubborn stains, grease, grime, and tough buildup from hard surfaces like concrete, brick, and stone. It's ideal for applications where surfaces can withstand the forceful impact of high-pressure water.

3. Applications:

Soft Washing: Soft washing is primarily used for delicate surfaces that require a gentle touch. It is commonly employed for cleaning roofs, siding, stucco, wood surfaces, fences, and other vulnerable areas where high-pressure water could cause damage. The specialized cleaning solutions used in soft washing help to kill and prevent the regrowth of mold, mildew, algae, and other organic matter.

Pressure Washing: Pressure washing is suitable for tougher surfaces that can withstand the force of high-pressure water. It is often used to clean driveways, sidewalks, decks, patios, concrete surfaces, and other hard exteriors. Pressure washing can efficiently remove grease stains, oil spills, chewing gum, graffiti, and deeply embedded dirt or grime.

4. Safety Considerations:

Soft Washing: Soft washing is considered a safer option for cleaning delicate surfaces, as it utilizes low-pressure water application. The chemical solutions used in soft washing are designed to be environmentally friendly and biodegradable, posing minimal risk to plants, animals, and humans. However, proper care should still be taken when handling and applying the cleaning solutions.

Pressure Washing: While pressure washing is highly effective for cleaning tough surfaces, it requires caution due to the high-pressure water stream. Improper use or directing the spray at vulnerable areas can result in surface damage, paint removal, or even personal injury. It's crucial to follow safety guidelines, wear protective gear, and be mindful of the surfaces being cleaned.


Soft washing and pressure washing are two distinct methods for cleaning and restoring exterior surfaces. Soft washing utilizes low-pressure water application and specialized cleaning solutions to gently eliminate contaminants from delicate surfaces. Pressure washing, on the other hand, employs high-pressure water to remove stubborn stains and debris from
