Outbreak Cleaning Guide


Cleaning & Disinfecting:

The CDC has ALWAYS recommended that you clean and then disinfect. We have a new video that explains why. It also explains why, with the widespread use of disinfectants, it's more important now than ever to consider using green cleaning products.



Video: Here's a video specific to our Critical Care product that explains how to pair it with a low-residue, low-toxicity cleaning product like H2Orange2.

The US EPA recently updated their list of products that are expected to be effective for the virus that causes COVID-19 by including disinfectants with a Human Coronavirus claim on the EPA Master Label: List N: Disinfectants for Use Against SARS-CoV-2

EnvirOx has two products from this list we'd like to highlight:

Non-Acid DisinfectantCritical Care


EnvirOx Critical Care (EPA# 72977-3 -69268): follow directions and let dwell for 3 minutes. The formulation is a Ready-to-Use product.
EnvirOx Non-Acid Disinfectant Concentrate (EPA# 10324-63 -69268): follow directions on the label for Virucidal Performance (4 oz per 5 gal) and let dwell for 10 minutes. The formulation is a concentrated product, requiring dilution. Note that the Human Coronavirus claim does not appear on this product’s affixed label, but the product does carry the claim on the EPA Master Label, and hence is on the list.





Does H2Orange2 Concentrate 117 or H2Orange2 Hyper-Concentrate 112 Kill the Coronavirus?

These products are NOT on the EPA LIst N. The EPA List N only contains disinfectants; no sanitizers are on the list. EPA-registered products with “human coronavirus” listed as a target pathogen on the product label are included on List N. EnvirOx® H2Orange2® Concentrate 117™ Sanitizer/Virucide Cleaner / Absolute™ EnvirOx® H2Orange2® Hyper-Concentrate 112 Sanitizer/Virucide Cleaner and EnvirOx® Fresh Concentrate 118™ Sanitizer/Virucide Cleaner are not disinfectants.  Rather they have an EPA registration as a sanitizer and a virucide.  The EnvirOx virucide claims do not contain the “human coronavirus”.  Hence these EnvirOx formulas do not contain the “approved virus claims” as mentioned by the EPA in this FAQ.

That doesn't mean H2Orange2 shouldn't be a key part of your cleaning program, however. See our videos above. You should always clean and then disinfect, and using a low-toxicity, low-residue in concert with a disinfectant is important now more than ever.


What does the column “emerging viral pathogen claim” indicate in List N?

This column of List N: Disinfectants for Use Against SARS-CoV-2 shows whether or not a product qualified for EPA’s emerging viral pathogen claim. If you see “yes,” that means the product qualified for an emerging viral pathogen claim. To do so, a product must demonstrate efficacy (e.g. effectiveness) against a harder-to-kill virus than SARS-CoV-2. If you see “no,” that means the product does not have an emerging viral pathogen claim.

These fall into two categories:

  • Products that have demonstrated efficacy against another human coronavirus similar to SARS-CoV-2
  • Products that EPA has approved for use against select viruses that are harder to kill than SARS-CoV-2, such as norovirus. 

EPA expects all products on List N to be effective against SARS-CoV-2 when used according to label directions, regardless of whether they have yes or no in this column. EnvirOx Critical Care (EPA# 72977-3 -69268): follow directions and let dwell for 3 minutes. The formulation is a Ready-to-Use product. EnvirOx Critical Care carries the EPA Emerging Pathogen Claim.


Can I apply a product using a method that is not specified in the directions for use?

Any time you use an EPA-registered disinfectant, you should read the product label and follow the directions, including the method of application. This is the best way to ensure the product will safely kill pathogens that cause human illness.

A disinfectant product’s safety and effectiveness may change based on how you use it. If a disinfectant product's label doesn't include disinfection directions for a certain method of application, EPA has not reviewed any data on whether the product is safe and effective when used in this way. EPA's regulatory process ensures that all registered disinfectant products legally sold in the United States include directions for use which, if followed, will allow a product to carry out its intended function without resulting in unreasonable adverse effects on the environment. Before using a product, always read its label and follow its instructions, including the application method.

EnvirOx has and will continue to only provide instructions for the use of our EPA registered products that are consistent with the product label.  Our priorities include the safety of the person using our products coupled with the effectiveness of our products in the cleaning and disinfection process.
