While both pressure washing and soft washing are methods used to clean exterior surfaces, they work in very different ways — and choosing the right one depends on the material you’re cleaning.
Pressure Washing
Pressure washing uses a high-powered stream of water, typically between 1,300 and 3,000 PSI, to blast away dirt, grime, mold, and other buildup. This method is excellent for hard, durable surfaces like concrete, brick, and some types of stone. The force of the water alone removes debris without the need for heavy chemical use. However, if applied to softer materials, it can cause damage such as chipping paint, denting siding, or etching wood.
Soft Washing
Soft washing uses a much lower pressure — often under 500 PSI — combined with specialized cleaning solutions to break down dirt, mold, algae, and mildew. Instead of relying on force, the process depends on these detergents to do the cleaning, making it safe for more delicate surfaces like roof shingles, painted siding, wood decks, and screens. It’s also effective for killing organic growth at its roots, helping to prevent regrowth for a longer period.
Which Should You Choose?
If you’re cleaning a tough, non-porous surface that can handle force, pressure washing is likely the better option. For more fragile materials, or when you want a deeper clean that targets biological growth, soft washing is the safer and more effective choice.
