Pressure Washing vs. Soft Washing: What's The Difference?

If you’re looking to clean your home’s exterior surfaces, you’ve probably come across the terms pressure washing and soft washing. While both methods are effective, they serve different purposes and are best suited for different surfaces. At Appalachian Softwash, our skilled pressure washing pros specialize in both techniques, ensuring your property in Marion stays clean, beautiful, and damage-free. Let’s dive into the key differences between pressure washing and soft washing to help you determine which method is best for your needs.

What Is Pressure Washing?

Pressure washing uses high-pressure water to remove dirt, grime, mold, and other debris from hard surfaces. The water is expelled at a powerful force, typically between 1,300 to 4,000 PSI (pounds per square inch), making it ideal for tough-to-clean areas.

Best Surfaces for Pressure Washing:

• Driveways & Concrete Surfaces – Removes oil stains, tire marks, and built-up grime.
• Brick & Paver Patios – Eliminates moss, dirt, and discoloration.
• Decks & Fences (Certain Materials) – Works well for durable wood and composite materials.
• Commercial Buildings & Parking Lots – Cleans sidewalks, storefronts, and high-traffic areas efficiently.

Since pressure washing relies on high force, it’s effective for stripping away stubborn stains, but it can be too aggressive for delicate surfaces. That’s where soft washing comes in.

What Is Soft Washing?

Soft washing is a gentler cleaning method that uses low-pressure water combined with specialized cleaning solutions to break down and remove dirt, mold, algae, and mildew. Unlike pressure washing, which relies on force, soft washing allows cleaning agents to do the work, safely lifting contaminants without damaging the surface.

Best Surfaces for Soft Washing:

• Roof Shingles – Prevents damage to asphalt, metal, or tile roofs while removing black streaks and algae.
• Siding (Vinyl, Stucco, & Wood) – Cleans without cracking, chipping, or peeling paint.
• Wooden Decks & Fences – Avoids splintering and erosion of softwood surfaces.
• Outdoor Furniture & Screens – Protects delicate surfaces from high-pressure damage.

Soft washing not only cleans but also kills organic growth at the root, preventing it from coming back too quickly. It’s the preferred method for roof cleaning and home siding because it ensures long-term results without risk of damage.

Which Method Is Right for Your Home?

Choosing between pressure washing and soft washing depends on the type of surface and the level of dirt or staining. At Appalachian Softwash, we evaluate each property carefully to determine the safest and most effective cleaning method.

• Use pressure washing for: driveways, concrete patios, and heavily stained hard surfaces.
• Use soft washing for: roofs, siding, and delicate surfaces that require a gentle touch.
