Soft washing is a cleaning method that uses low-pressure water mixed with specialized cleaning solutions to safely remove mildew, bacteria, algae, and other organic stains from roofs and other building exteriors. Unlike pressure washing, which relies on high-pressure water to clean surfaces, soft washing is gentler and more effective for certain applications.
It is essential for maintaining the exterior of homes and commercial properties. It helps preserve the integrity of surfaces, prevents damage, and ensures a clean and appealing appearance. This guide is designed for homeowners, DIY enthusiasts, and professionals starting a soft washing business. By the end of this post, you’ll have a complete list of essential tools to get started safely and effectively.
What is Soft Washing?
Soft washing is a cleaning technique that uses a low-pressure pump system to apply a mixture of water and cleaning solutions to surfaces. This method is ideal for cleaning roofs, siding, fences, decks, stucco, and more.
Benefits Over Pressure Washing
- Gentler on Surfaces: Soft washing prevents damage to delicate surfaces that high-pressure washing can cause.
- Effective Mold and Algae Removal: The cleaning solutions used in soft washing are specifically designed to kill mold, mildew, and algae, ensuring a thorough clean.

Soft washing is the right choice when dealing with surfaces that are prone to damage from high pressure, or when you need to remove organic stains effectively.
