Cleaning Table

Will the product wipe off?

Sporicidin

Yes. According to the Healthy Housing Institute, “under conditions found in most homes and offices, active ingredient residues evaporate at a rate of roughly 50% in a 24 hour period.” Sporicidin’s natural decomposition makes it easier to wipe off.

Sporicidin is not EPA-approved for use on porous surfaces, which can include furniture and wallpaper. Sporicidin will not stain carpets, as it is EPA-approved “to clean, deodorize, sanitize, and remove debris from carpets.”

BioShield

Like Sporicidin, BioShield 75 is not EPA-approved for use on porous surfaces, which can include furniture and wallpaper. BioShield 75 will not stain carpets, as it is EPA-approved for use on them.

Disinfexol

Disinfexol is not EPA-approved for use on porous surfaces, which can include furniture and wallpaper. Disinfexol also is not EPA-approved for use on carpets.

Nouvex

Nouvex will not stain furniture, as it is EPA-approved for use in it. Nouvex is not EPA-approved for use in wallpaper or carpets.

Swimming Pool

Does the product work outside?

Sporicidin

Yes. It is EPA-approved on hard, nonporous surfaces outdoors

BioShield

Yes, BioShield 75 is also EPA-approved for outdoor use.

Disinfexol

Disinfexol works outside. HOCl decomposes after about four days of sunlight (see the journal article: Some Factors Influencing the Stability of Sterilox, a Super-Oxidised Water). According to its EPA Master Label, Disinfexol can be used to clean, disinfect, and sterilize hard, non-porous surfaces.

Nouvex

Nouvex will work when sprayed onto outdoor surfaces. However, it may wash off after rain.

Cleaning the Counter

Can I apply it myself? Should I wear PPE?

Sporicidin

You can spray Sporicidin yourself. Eye protection is necessary; other forms of PPE may prevent mild irritation.

BioShield

You can spray BioShield 75 yourself. 1 gallon of BioShield 75 covers about 200 ft2 of surface area. Its EPA Master Label advises you to “wear protective eyewear (goggles or face shield), gloves, and protective clothing when using this product.”

Disinfexol

You can apply Disinfexol yourself. Its EPA Master Label advises you to “wear safety glasses or goggles [and] wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, using tobacco or using the toilet.”

Nouvex

You can apply Nouvex yourself. When spraying it, ensure adequate ventilation and use a suitable particle arresting respirator, safety glasses with side shields, rubber gloves, and an apron and lab coat.

Thermometer

What about temperature range for application?

Sporicidin

Sporicidin has no safety concerns when applied at moderately depressed or elevated temperatures. Based on principles of antimicrobial function, room temperature or above is ideal for maximum effectiveness. However, make sure to store Sporicidin at room temperature.

BioShield

According to the EPA Master Label for BioShield 75, any temperature ranging from room temperature to 320 F provides suitable spraying conditions. This is the ideal range for polymerization, providing stronger bacteriostatic and fungistatic action.

Disinfexol

Disinfexol has no safety concerns when applied at moderately depressed or elevated temperatures. Based on principles of antimicrobial function, room temperature or above is ideal for maximum effectiveness. However, make sure to store Disinfexol at room temperature.

Nouvex

Practically, no. Nouvex degrades around 225 0C (~437 0F). Store Nouvex at room temperature in a dry area.

Calendar

How long has the product been around?

Sporicidin

According to the Pesticide Product and Label System, Sporicidin was first registered with the EPA in 1971.

BioShield

According to the Pesticide Product and Label System, BioShield 75 was first registered with the EPA in 2000.

Disinfexol

Stack of Magazines

What items cannot be sprayed?

Sporicidin

Sporicidin is not EPA-approved to spray on paper, as paper is porous. Sporicidin is EPAapproved to spray on glass. Sporicidin is also EPA-approved to spray on computers. If you are planning on spraying a laptop/desktop computer, we recommend leaving it on, which allows the fans to run. See the journal article: Evaluation of a Dry Fogging System for Laboratory Decontamination.

BioShield

BioShield 75 is not EPA-approved to spray on paper, as paper is porous. BioShield 75 is not EPA-approved to spray on glass, either. Spraying it on glass leaves a residue. BioShield 75 is not EPAapproved to spray on computers.

Disinfexol

Disinfexol is not EPA-approved to spray on paper, as paper is porous. Disinfexol can be sprayed on glass, and it leaves no residue. BioShield 75 is not EPA-approved to spray on computers.

Tech Watch

How long does the product work?

Sporicidin

The EPA Master Label for Sporicidin makes no guarantee for persistency. According to the Healthy Housing Institute, “under conditions found in most homes and offices, active ingredient residues evaporate at a rate of roughly 50% in a 24 hour period.”

BioShield

The EPA Master Label for BioShield 75 implicitly guarantees persistency. This can be attributed to BioShield 75’s covalent bonding to surfaces. The label recommends reapplying BioShield 75 “every three months or when odor, staining, and discoloration due to bacteria, mold stains, and mildew stains return.”

Disinfexol

The EPA Master Label for Disinfexol makes no guarantee for persistency. According to the Healthy Housing Institute, “under conditions found in most homes and offices, active ingredient residues evaporate at a rate of roughly 50% in a 24 hour period.” Even though it evaporates, Disinfexol’s bacteriostatic effects remain after extensive washings. See the journal article: The Inhibition of Bacterial Growth by Hypochlorous Acid. Possible Role in the Bactericidal Activity of Phagocytes.

Nouvex

Depending on the surface type and amount of wear on the surface, a surface sprayed with Nouvex can likely be antimicrobial for years.

Organized Desk

What do we need to do to prepare for application?

Sporicidin

Move the items that you don’t want sprayed out of the way. The previous answers to the FAQs provide guidance. If a surface is visibly soiled, Sporicidin will be more effective if it is cleaned before spraying.

BioShield

Move the items that you don’t want sprayed out of the way. The previous answers to the FAQs provide guidance. If a surface is visibly soiled, BioShield 75 will be more effective if it is cleaned before spraying.

Disinfexol

Move the items that you don’t want sprayed out of the way. The previous answers to the FAQs provide guidance. Precleaning surfaces is unnecessary because Disinfexol has both cleaning (via OCl-) and disinfecting (via HOCl) properties.

Nouvex

Move the items that you don’t want sprayed out of the way. The previous answers to the FAQs provide guidance. If a surface is visibly soiled, Nouvex will be more effective if it is cleaned before spraying.

Does the product kill COVID-19?

Sporicidin

Yes. It is on the EPA’s List N for Disinfectants for Use Against SARS-CoV-2 (COVID-19).

BioShield

Most likely. Although not yet on List N, private laboratory results on testing of a coronavirus “showed significant viricidal activity both immediately upon application and after application.”

Disinfexol

Most likely. SARS-CoV-2, the virus that causes COVID-19, is surrounded by a lipid bilayer. The lipid bilayer encloses the essential components of the cell, including DNA, RNA, and enzymes. HOCl can easily pass through the lipid bilayer. Once inside the cell, HOCl damages cellular components, chlorinating the nucleotides of DNA and RNA and oxidizing enzymes.

Nouvex

Most likely. Nouvex has been shown to kill both gram negative and gram positive bacteria. Similar to gram negative bacteria, SARS-CoV-2 is surrounded by a lipid bilayer, so Nouvex should be equally well equipped to disrupt SARS-CoV-2.

Cleaning Sink

Do I clean as normal after application?

Sporicidin

Yes. Cleaning surfaces sprayed with Sporicidin will speed up its decay, but continual cleaning is necessary because Sporicidin decays naturally.

BioShield

BioShield 75 will remain on the surface after cleaning. Cleaning the surface will enhance its effectiveness, as it collects dead bacteria and fungi.

Disinfexol

Yes. Cleaning surfaces sprayed with Disinfexol will not affect its decay (see the journal article: The Inhibition of Bacterial Growth by Hypochlorous Acid. Possible Role in the Bactericidal Activity of Phagocytes). Continual cleaning is necessary because Disinfexol decays naturally.

Nouvex

No. Cleaning a surface that has been sprayed with Nouvex will cause the Nouvex to wear off.
