Cleaning the Way Nature Intended

Algae Knockout


  • Naturally removes algae from a variety of surfaces.
  • Easy to use with no grueling scrubbing or damaging power-washing. Simply spray and leave – that’s it.
  • Bleach does not remove algae – it simply bleaches the algae and requires pain-staking scrubbing and rinsing.
  • Bleach treatments only last a few weeks, and algae will re-appear. Pure Earth Naturally™ Algae Knock Out lasts up to six months.
  • Fantastic for siding, fences and decks.

Usage Guide: Apply by liberally spraying the affected surfaces making sure to completely saturate the entire area. Within 48 hours or less, the algae will disappear. For heavy algae build-up, a second application may be required. 

Ingredients: Enzymes, plant extracts and water.
