What is Soft Washing? (Why It's Safer Than Pressure Washing)

If you're a homeowner in Florida, you know the struggle: green algae on the siding, black streaks on the roof, and mildew everywhere. Your first instinct might be to blast it away with a high-pressure washer. Stop right there!

Soft washing is the modern, safe alternative to pressure washing for delicate surfaces like roofs, stucco, and vinyl siding.

How Soft Washing Works

Unlike pressure washing, which relies on brute force (up to 4,000 PSI), soft washing uses specialized pumps to apply biodegradable cleaning solutions at very low pressure—about the same as a garden hose.

The "magic" isn't in the pressure; it's in the solution. Soft wash mixes typically contain:

• Sodium Hypochlorite: To kill mold, mildew, and algae spores at the root.
• Surfactants: To help the solution stick to vertical surfaces and loosen dirt.
• Water: To dilute the mix safely.

Why Pressure Washing Can Be Dangerous

Using high pressure on a roof can strip the granules off your shingles, voiding the warranty and reducing its lifespan. On stucco or siding, high pressure can force water behind the weather barrier, leading to invisible mold growth inside your walls.

The Verdict

For effortless, long-lasting results that won't damage your home, soft washing is the clear winner for exteriors and roofs. Save the pressure washer for the concrete driveway!
