FAQ

Who Will Use ALLCLIR?

Schools, universities, military, airlines, public transportation, office buildings, medical buildings, dental offices, stores, gyms, restaurants and bars, hotels, Airbnb hosts, property management companies, cruise ships, car rentals, Uber and Lift drivers, car dealerships, equipment rentals. ... The list goes on and on.

How does ALLCLIR work?

The “ALLCLIR” sensor utilizes the deprotonation reaction when in contact with ammonia- or chlorine- or thymol- or hydrogen peroxide-based disinfectants. The reaction flips the chemical indicator to a different color by releasing a hydrogen ion (i.e. a proton) when binding instead with the disinfectant agent molecule.

Can ALLCLIR sensors be customized?

Allclir has a production capacity in the USA of 4.8 million units per day. Yet we are indeed a bespoke shop. Not sure your disinfectant will work with our sensor? We'll test it out and make a special sensor for it if need be. Want tape instead of stickers? No problem. Want to deploy using a sticker gun? Sure thing. Want an especially inconspicuous sticker for covert auditing? Say no more. Want sensors in tag form to attach to plants, to help you fight mold? No problemo. Want to co-brand with your logo? Of course. Co-brand in terms of shape? We can do that too. 

What’s the difference between products that disinfect, sanitize, or clean surfaces; and what is sterilization?

At the EPA, products used to kill viruses and bacteria on surfaces are registered as antimicrobial pesticides.

Yes, sanitizers and disinfectants are two types of antimicrobial pesticides. The Food and Drug Administration (FDA) regulates hand sanitizers, antiseptic washes, and antibacterial soaps, i.e. pesticides for use on people. Here, however, we are not talking about products used on people.

Disinfectant products for use on inanimate surfaces are subject to more rigorous EPA testing requirements and must clear a higher bar for effectiveness than sanitizing products for use on inanimate surfaces.

There are no sanitizer-only products with EPA-approved virus claims. For this reason, sanitizers do not qualify for inclusion on the EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19).

There are many products registered with the EPA as both sanitizers and disinfectants because they've been tested using both standards. These products are eligible for inclusion on the EPA’s List N because of their disinfectant claims. When using these products, follow the directions for virucidal disinfection, and pay close attention to the contact time, which is how long the surface must remain "visibly" wet, i.e. about 10 microns of liquid depth. This can often be several minutes.

Cleaning products must be registered by the EPA if they make pesticidal or disinfection claims on their labeling, such as controlling a pest, bacteria or virus. Otherwise cleaning means just removing unwanted macroscopic material. Cleaning is nevertheless fundamentally important in relation to disinfection and sanitation because disinfection and sanitization claims are made in relation to an already clean(ed) surface. In practice, cleaning should be performed thoroughly before disinfection or sanitation.

As for sterilization, that's a matter for laboratories and surgical instruments and such; it's not a matter of public health. Sterilization means killing not just a certain percentage (e.g. 99.9999%) of a certain list of bacteria and viruses but killing almost certainly all conceivable lifeforms within a surface or space.

What is "contact time" and how is ALLCLIR related to it?

Please see our "Dwell Time" page.

What does OHSA say?

“If you oversee staff in a workplace, your plan should include considerations about the safety of custodial staff and other people who are carrying out the cleaning or disinfecting. These people are at increased risk of being exposed to the virus and to any toxic effects of the cleaning chemicals. These staff should wear appropriate PPE for cleaning and disinfecting. To protect your staff and to ensure that the products are used effectively, staff should be instructed on how to apply the disinfectants according to the label. For more information on concerns related to cleaning staff, visit the Occupational Safety and Health Administration’s (OSHA) website on Control and Prevention."

What about disinfecting with ozone?

Ozone has issues.

For one thing, ozone is very dangerous to your mucous membranes (e.g. throat, lungs)  so much so that California, for instance, has outlawed the sale of ozone generators to the general public. Ozone can also damage materials such as rubber, electrical wire coating, fabrics, and artwork.

By the same token, disinfection with ozone takes about an hour of fogging followed by about 2 hours of airing out. So, three hours minimum before staff or customer can enter the space.

What's more, as yet there is no scientific proof ozone disinfects sufficiently against SARS-CoV2 (2019). Ozone is not on the EPA approved "List N" of disinfectants for killing SARS-CoV-2 (COVID-19).

From https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7595067/:

Ozone was shown to be highly effective to inactivate the [original, 2002] SARS virus, in fact, it shows an inactivation rate not lesser than 99%. The novel SARS-CoV2 (2019), an enveloped virus like all other coronaviruses, shows 80% of genome sequence similarity to SARS-CoV (2002) and this suggests that ozone could be equally effective also on the novel coronavirus. ...

In conclusion, although the existing scientific literature supports the effectiveness of ozone in the inactivation of viruses, there are very few studies about it on the SARS virus and not still a single study about its efficiency of inactivation on SARS-CoV-2. Therefore, in the absence of scientific literature, it is possible to assume that ozone is equally effective in inactivating SARS-CoV-2, however specific studies must be conducted to know also the ozone dose and effective exposure times.

How about disinfecting with steam?

Steam works to disinfect and even sterilize items in a highly controlled environment, e.g. an autoclave in a hospital or laboratory. 

But disinfection by steam means controlled temperature, pressure, and time – lots of time.

From Consumer Reports, August 2, 2020:

[H]ow high does the temperature need to be? According to Philip M. Tierno, Ph.D., a clinical professor of microbiology and pathology at New York University, most pathogens, including the coronavirus, will die at 212° F.

Steam mops can get up to that temperature, but you’d have to hold the mop in place for at least 10 minutes at a time for it to be effective. And that’s the catch: Steaming your floor for minutes at a time can kill pathogens—and also damage your floor. (Steam can pop tiles and force its way under wood floor boards and warp them.)

Furthermore, some steam mops require you to manually pump them to generate steam, which means the temperature may fluctuate, making it hard to tell whether you’re really killing any germs. 

From Scientific American, March 27, 2020:

And some cleaning methods have only mixed support. The Environmental Protection Agency has put out a list of approved disinfectants for use against SARS-CoV-2, but the list currently only includes chemicals. Olinger said that, based on current evidence, while steam can kill the virus, it needs a lengthier application time than some users may realize. [Patty Olinger is executive director of the Global Biorisk Advisory Council, a division of ISSA, a cleaning industry trade association.] “At this point during the pandemic I would not use steam at all,” Wilcox wrote, citing a lack of strong evidence. [Heidi Wilcox is a microbiologist and commercial cleaning consultant.]

What are the benefits of using ALLCLIR?

Please see our "Benefits" page.

    How long does the color change last?

    The ALLCLIR reaction is irreversible and tamper-resistant. Since they are single use sensors, we strongly recommend carefully filing them after use, for auditing purposes. 

    How long does the reaction take?

    This reaction for all sensors is virtually instantaneous upon sufficient contact with the disinfectant to meet the "kill" percentage (e.g. 99.99%) listed on the disinfectant's label. 

    What is the lower limit disinfectant concentration ALLCLIR can detect?

    The sensor is designed to detect concentrations of disinfectant that is consistent with what is recommended by the CDC. The sensors work down to 100 ppm!

    Who created it?

    ALLCLIR was created by nanotechnologists and inorganic chemists. ALLCLIR is the first visual platform that brings PROOF to disinfecting protocols. 

    What types of disinfectants do the CDC and EPA recommend for disinfection of SARS-CoV-2 (COVID-19)?

    It's an EPA thing, because we are basically talking about a pesticide. Click here for the EPA approved "List N" of disinfectants for killing SARS-CoV-2 (COVID-19).

    How is ALLCLIR tamper resistant?  

    It is tamper resistant in that it does not work with any other forms of reagents that it is not intended to work with. 

    Does ALLCLIR offer its own disinfectant brand?

    No, we partner with existing disinfectant brands and sprayer brands and the companies that distribute and use them.
