R4 Clean is Your Solution for food safety

Protect Your Investments with Disinfection & Decontamination

Through the use of cold plasma technology, R4’s food safety division aims to protect our food supplies and distribution networks from ever-increasing pesticide resistant microbial organisms, addressing the need for better disinfection protocols throughout the entire food production process.

Working with TOMI™, a pioneer in EPA-Registered equipment and solution disinfection, we utilize SteraMist® and it’s trusted, innovative Binary lonization Technology (BIT™) to reduce cross-contamination risks associated with manual cleans. ionized Hydrogen Peroxide (iHP™) disinfects previously cleaned non-porous food contact surfaces and equipment through cold plasma science.

  • Processing & Packaging
  • Storage & Prep Areas
  • Pre/Post-Harvest
  • Cargo & Transport

Innovating for a Safer World®

At R4, our mission is to help our customers create a healthier world through a wide variety of disinfection and decontamination services. We use a range of TOMI solutions, including SteraMist branded products and services featuring iHP™. TOMI is an industry-leading innovator with a commitment to ongoing research, supporting customers on all levels of disinfection, from seed to table.

The Science Behind Binary Ionization Technology®

Understanding the Power Behind SteraMist® Disinfection

A Brief Summary of ionized Hydrogen Peroxide (iHP)


The atmospheric cold plasma arc converts the H,O, molecules into iHP. As one of the most powerful oxidizing agents in nature, the iHP kills the pathogens achieving high efficacy and leaves behind only oxygen and humidity in treated spaces.A Brief Summary of ionized Hydrogen Peroxide (iHP™)

The ionized Hydrogen Peroxide Process

  1. COLD PLASMA 7.8% hydrogen peroxide BIT Solution converts to iHP after passing through a cold plasma arc.
  2. DISPERSION iHP is carried throughout the mist, moving like a gas throughout the treated area.
  3. CONTACT iHP damages pathogenic organisms through oxidation of proteins, carbohydrates, and lipids.
  4. DISRUPTION Cellular disruptions and/or dysfunctions occur and allows for disinfection & decontamination in the targeted area.
