When it comes to exterior cleaning, soft washing and pressure washing are two of the most common methods professionals use. While both can remove dirt and buildup, they rely on very different approaches.
Pressure washing uses high-pressure water to break dirt and grime away from durable surfaces. Soft washing relies more heavily on cleaning solutions and lower water pressure to treat organic growth and clean surfaces that may be damaged by excessive pressure.
For professional cleaners, property maintenance teams, and contractors, understanding the difference can help you choose the right cleaning method and cleaning equipment for each job.
What Is Pressure Washing?
Pressure washing uses a high-pressure stream of water to remove dirt, mud, grime, and other buildup from surfaces. Commercial pressure washers are available in numerous pressure and flow configurations, allowing contractors to match their equipment to the type of cleaning they perform.
Pressure washing is commonly used for:
- Concrete and sidewalks
- Parking areas
- Construction equipment
- Fleet vehicles
- Machinery
- Commercial facilities
- Driveways and other hard surfaces
One of the biggest advantages of pressure washing is its ability to handle stubborn buildup quickly. Commercial pressure washing equipment can also be paired with surface cleaners, specialized nozzles, detergents, and other accessories to improve productivity.
For grease, oil, and particularly difficult grime, a hot water pressure washer can provide additional cleaning power by combining pressure with heat.
What Is Soft Washing?
Soft washing takes a different approach. Rather than depending primarily on high water pressure, a soft wash system applies cleaning solutions at lower pressure.
The cleaning solution does much of the work, helping treat contaminants such as algae, mildew, mold, and other organic buildup before the surface is rinsed.
Soft washing is commonly used on surfaces such as:
- Roofs
- Siding
- Stucco
- Painted surfaces
- Building exteriors
- Other pressure-sensitive materials
Because lower pressure is used, soft washing can be a better option when high pressure could damage the material being cleaned.
Soft Washing vs. Pressure Washing
The primary difference comes down to how each method cleans.
Pressure washing uses water pressure as the primary cleaning force. It works especially well on durable surfaces and heavy accumulations of dirt, mud, and grime.
Soft washing uses cleaning solutions as the primary cleaning force. The lower-pressure application makes it useful for surfaces that require a gentler approach or for jobs involving organic growth.
Neither method replaces the other. Professional exterior cleaning companies often use both because different surfaces and contaminants require different cleaning techniques.
When Should You Use a Pressure Washer?
Pressure washing is generally the better choice when you’re cleaning a durable surface that can safely withstand higher pressure.
For example, a contractor cleaning concrete sidewalks or removing caked-on mud from equipment may benefit significantly from the cleaning force of a commercial pressure washer.
Pressure washing is also highly adaptable. Different nozzles, pressure settings, detergents, surface cleaners, and accessories can help configure the equipment for specific applications.
For businesses dealing with oil and grease, hot water pressure washing can be especially effective. Heat helps break down oily contaminants, making it an important option for automotive, transportation, manufacturing, construction, and other industrial applications.
When Should You Use a Soft Wash System?
Soft washing makes sense when the surface requires lower pressure or when organic growth is the primary cleaning concern.
A roof, painted exterior, or certain types of siding may not be appropriate for aggressive high-pressure cleaning. A properly configured soft wash system allows cleaning chemicals to treat the contamination without relying on excessive pressure.
For professional exterior cleaning companies, adding soft washing capabilities can also expand the types of jobs they can handle.
Instead of limiting your business to concrete, pavement, equipment, and other pressure-washing applications, you can take on roofs, siding, building exteriors, and other surfaces that benefit from lower-pressure cleaning.
Do Professional Cleaning Companies Need Both?
For many exterior cleaning businesses, the answer is yes.
Having both pressure washing and soft washing capabilities gives you more flexibility in the field. A single property may even require both methods.
For example, a commercial cleaning job could include soft washing the building exterior while pressure washing sidewalks, concrete entrances, and parking areas.
The right setup depends on the type of work you perform, your customers, and the surfaces you encounter most often.
Building a Soft Wash and Pressure Washing Setup
Professional cleaning businesses also need to consider how their cleaning equipment works together.
A complete mobile cleaning setup may include:
- Hot or cold water pressure washers
- Soft wash equipment
- Water and chemical pumps
- Water tanks
- Chemical tanks or application systems
- Hose reels
- Surface cleaners
- Pressure washer accessories
- Water reclamation equipment
- Trailer-mounted equipment
Building the system around your actual cleaning applications can make your crew more efficient and reduce the need to improvise from one job to another.
