Pressure Washing vs Soft Washing: What's the Difference and Which is Right for Your Property?

When it comes to cleaning the exterior of your home or commercial property, not all dirt is created equal—and neither are the cleaning methods. Two of the most effective techniques used by professional exterior cleaning companies are pressure washing and soft washing. While both aim to restore surfaces to a clean, fresh state, they operate quite differently and are suited for different jobs. Choosing the right method can mean the difference between a sparkling clean surface and costly damage.

Let’s break down what each method involves and help you understand which is best for your cleaning needs.

What is Pressure Washing?

Pressure washing uses a high-powered stream of water—typically at pressures ranging from 1,800 to over 3,000 PSI and 2GPM to 5.5 GPM —to blast away stubborn dirt, grime, mold, algae and stains from surfaces. It’s commonly used on hard, durable materials such as:

●      Concrete driveways and sidewalks

●      Brick walls

●      Stone patios

●      Metal surfaces

This method is especially effective at removing surface stains, old grime buildup and even flaking paint or rust. However, the very power that makes pressure washing effective also makes it risky if used incorrectly.

If too much pressure is applied or the wrong angle is used, pressure washing can chip paint, crack tiles, or even etch and damage concrete or stone surfaces. That’s why it’s important to leave this task to experienced professionals who know how to balance power and precision.

What is Soft Washing?

Soft washing, on the other hand, is a much gentler cleaning method. It uses low-pressure water combined with specialised cleaning solutions to remove dirt, mildew, algae and other contaminants. Rather than relying on force, soft washing lets the cleaning agents do the heavy lifting.

Soft washing is ideal for more delicate or treated surfaces, such as:

●      Roof shingles and metal roofing

●      Vinyl or metal sidings

●      Painted surfaces

●      Outdoor furniture

●      Certain types of concrete

Because it uses less force, soft washing minimises the risk of surface damage. The cleaning solutions used in soft washing also have the added benefit of killing mold, mildew and algae at the root, meaning your surfaces stay cleaner for longer.
