How to Wash Vegetables with Ozone Generator

Aqua-6 Aqua-8 Water Applications

“Produce is sold out in the open where anyone can handle it, and it comes from the soil, so there could be dirt on it,” Linda Harris, a department chair and food-safety researcher at the University of California, Davis told TIME

Washing produce with tap water and rubbing with a paper towel is an effective cleaning method, however introducing ozone can provide an added layer of security.

  • The shelf life of fruits and vegetables can be extended by ozone treatment.
  • To help keep produce fresh, follow these steps:
    • Fill your sink or a large bowl with water.
      • We recommend using a glass bowl, as ozone will degrade plastic over time.
    • Average sized sinks should be half-full.
    • Place the diffusion stone 2 to 4 inches deep into the water
    • Place the vegetables and or fruits to be treated in the water
    • Operate the Aqua-8 or Aqua-6 for 10 minutes
    • For the Aqua-8, this is Function #5.
    • If using the Aqua-6, this is Function #3.
    • Ozone has a half-life of 30 minutes in water. 
    • Allow the produce to sit in the ozonated water for up to 30 minutes. 
    • Next, remove the produce from the ozonated water and enjoy!
