What Customers Are Saying

Customers overwhelmingly praise this outdoor cleaner for powerfully removing mold, mildew, algae, and grime from siding, concrete, decks, and fences with minimal effort. Most appreciate that it requires only dilution with water, spraying, brief dwell time, and rinsing—no power washing or scrubbing needed. Many highlight the concentrated formula's excellent value, noting it produces large volumes of cleaner from one bottle. A few mention strong chemical odor or occasional need for second applications on tough spots, but these minor drawbacks barely diminish the overwhelming consensus that this delivers dramatic, transformative results efficiently.

Its really works!

Would Recommend

This product actually works. Used full strength on large mildewed spots on my concrete patio. Let it sit awhile, used a hand brush to work the area, then hosed off the area and amazingly, the mildew was gone. With so little effort!
