What Chemicals Are Used For Soft Washing?

There are numerous ways to soft wash your roof and home siding. You can either do it yourself or hire a professional to do the job. Irrespective of your chosen method, this article will guide you about the kind of soft wash chemicals required for soft washing.

Professionals use a blend of professional-grade sodium hypochlorite (12.5%) or parts of bleach mixed with water. These soft wash chemicals help kill primary organisms such as mold, lichen, algae, moss, and mildew that grow on the surface.

For professionals to do safe, efficient and smart soft-washing, additional products are required, which are discussed below in the article. 

Soft Washing vs. Power Washing

As similar as soft and power washing may sound, they both use distinctive techniques, pressure, chemicals, and equipment. 

Soft washing uses a low-pressure cleaning technique using a blend of bleach, algaecides, surfactants, and water to clean the exteriors with mildew, organic stains, and algae growth. 

On the other hand, power washing uses high-pressure water to clean the surface, usually with hot water. So it’s ideal to use pressure washing chemicals when power washing.

It would be best if you opted for soft washing surfaces that are difficult to pressure clean or are delicate enough to be damaged by high pressure, such as wooden panels, screens, windows, or roof shingles. 

Soft washing was specifically designed to clean algae off the roof shingles.

How To Soft Wash?

Compared to pressure washing, soft washing chemicals use a higher concentration of cleaning solutions and more water-to-chemical ratio, the application is gentle compared to that of a garden hose. 

Roof concentrations are usually higher where the chemicals are left on the surface for deep cleaning and ensuring that all organisms are killed. On a siding, it’s usually rinsed off instantly.

Follow these simple steps for a soft wash:

  1. Prep The Surrounding Area: Protect greenery such as grass or plants surrounding the area that needs to be cleaned. 
  2. Prepare The Solution: Identify what needs to be cleaned and then prepare the solution accordingly. 
  3. Application On The Surface: Once the solution is prepared, load it in a spray bottle. The pump and hose of the spray bottle ensure minimal pressure to run the soft wash. 

Chemicals Used To Soft Wash

Before identifying the chemicals, get your hands on a soft wash system. You will need the right kind of nozzle to adjust the pressure. There are several retailers in the market where you can get the equipment, do check out the South East Soft Wash equipment section.

Once the equipment is sorted, we can now proceed to the chemicals:


Bleach takes time to kill the organic matter. When mixed with parts of water, the bleach solution runs quickly down the roof and siding, which is why you need to rinse multiple times since it does not have the staying power. 

The process takes up a lot of time, wastes water and bleaches, and threatens the surrounding greenery. Also, bleach does not support the removal of dirt and grime; the water’s pressure may knock them off, but there are no guarantees. 

This is where surfactants step in; they are surface-acting agents that minimize the surface tension of water for an even spread. Also, surfactants support the loosening of dirt and grime by deeper penetration which helps rinse the contaminants. 

When looking for surfactants, you want them to stick, and nothing is more befitting than the South East Soft Wash products.
