Odor Eliminator: How to Use and Pro Tips

This article contains everything you need to know about our OtO Odor Eliminator solution.



What is OtO Odor Eliminator?

OtO Odor Eliminator is an all-natural enzymic cleaning solution that quickly and effectively neutralizes and removes unpleasant smells from grass, turf, concrete and patios.

  • Removes tough odors left behind urine, stool, vomit, and more
  • Safe for use on grass, artificial turf, gravel, concrete, brick, and more
  • Powerful, industrial-strength enzyme formula
  • Biodegradable, non-toxic and safe for use around pets

How it Works

  1. Scan the QR code on the solution bottle using the OtO Lawn App and choose which zones you'd like to assign the Odor Eliminator. You do not have to assign the solution to every zone.
  2. To each zone that you've assigned the solution, OtO will run the solution on the default setting. 
    1. If you want to change the default settings, you can tap the solution icon within the zone to be taken to the solutions settings menu.
  3. OtO will send a push notification to your phone when it is applying solution, so you know when it is watering versus applying solution
  4. With regular use, each bottle lasts 2 months

Is Odor Eliminator safe to use around pets?

Yes! Being safe for pets, people, and the planet is incredibly important to us here at OtO. Odor Eliminator is biodegradable, non-toxic and is safe for use around kids and animals. However, as with any cleaning product, certain safety measured need to be followed while applying. For example, this solution should not be sprayed directly on people or animals, and pets should be kept out of the area while OtO is spraying.

    Does solution only literally mean solution only? Or does that mean solution mixed with water but not a “watering cycle”?

    Great question! Yes, solution only means there will be no watering schedule. However, a VERY small amount of water is added during a solution application.
