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.

This Cleans the vinyl siding and Trex porch great. I use it every spring to clean the siding and the screened porch. Just spray it ion and leave it 10-15 minutes and then rinse. Does an excellent job!
