Disinfection of Building Surfaces
A number of cleaners and disinfectants used on building surfaces, such as in hospitals or when cleaning a building after a sewage backup, but keep in mind that these cleaners, sanitizers, or disinfectants are for building surfaces, not for use on foods such as produce.
Check the cleaning product for approval for its intended use (US EPA list at epa.gov/listn )
Read the instructions provided by the product manufacturer, usually printed on the product labels
Pre-clean the surface using ordinary cleaners like soap and water if the surface is visibly dirty or as recommended in your disinfectant product's instructions
Wear appropriate protective gear before using the disinfectant, such as goggles, disposable gloves, mask
Apply the disinfectant to the surface as directed, often by spray, wetting the surface
Wait the required contact time. Some products are wiped off, others are left to air-dry
Wash your hands after using the product
Keep harmful chemicals out of reach of children
What's the Difference Between Cleaning, Sanitizing, and Disinfecting?
In order of reduction of pathogens on surfaces we use the US EPA's following definitions:
Cleaning physically removes germs, dirt, and impurities from surfaces or objects. Cleaning works by using soap (or detergent) and water combined with scrubbing to physically remove germs from surfaces. Cleaners may be soap or detergents combined in water.
This process does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.
For some sanitizers or disinfectants to be effective, depending on the product instructions, the surface may have to be physically cleaned first.
Sanitizing lowers the number of germs on surfaces or objects to a safe level, as judged by public health standards or requirements. Typically a sanitizer's label will indicate that it kills 99% of the organisms ("germs") listed on its label.
Watch out: organisms that are not listed on the sanitizer label may not be killed or may not be killed at that same high level.
This process works by either cleaning or disinfecting surfaces or objects to lower the risk of spreading infection.
A non-food-contact surface sanitizer is “a substance, or mixture of substances, that
reduces the bacterial population in the inanimate environment by significant numbers, (e.g., 3-log10 reduction) or
more, but does not destroy or eliminate all bacteria. (EPA Sanitizers 2012)
Disinfecting kills close to 100% of harmful organisms (germs) on surfaces or objects. Disinfecting works by using chemicals to kill germs on surfaces or objects.
Watch out: Like sanitizers, a disinfectant may not kill some or all of organisms that are not listed on its label.
This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection. - (U.S. EPA 2021)
a disinfectant is a “substance, or mixture of substances, that destroys or irreversibly
inactivates bacteria, fungi and viruses, but not necessarily their spores. (EPA Pesticide manual 2011)

Notes to the table above
Watch out: these disinfectants are for surface disinfection: they are NOT appropriate for produce or other foods
Watch out: be sure to use disinfectants, sanitizers, and cleaners as directed by the manufacture. Mixing chemicals or cleaners or using in an un-ventilated space or getting a some chemicals in one's eyes or on the skin can be quite dangerous.
Alcohol surface-disinfectant: Dilute 90% or 70% ethanol or isopropyl alcohol with 30% water to slow evaporation and improve disinfection.
Since alcohol is flammable, limit its use as a surface disinfectant to small surface-areas and use it in well-ventilated spaces only. - U.S. NIH cited at References:
See Rutala, William A., Ph.D., M.P.H. & David J. Weber, M.D., M.P.H., CHEMICAL DISINFECTANTS [PDF] [Live link given at Research: below], U.S. CDC, retrieved 2022/05/15, original source: https://www.cdc.gov/infectioncontrol/guidelines/disinfection/disinfection-methods/chemical.html
Excerpt: Alcohol: In the healthcare setting, “alcohol” refers to two water-soluble chemical compounds—ethyl alcohol and isopropyl alcohol—that have generally underrated germicidal characteristics 482.
FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient.
These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores.
Their cidal activity drops sharply when diluted below 50% concentration, and the optimum bactericidal concentration is 60%–90% solutions in water (volume/volume) 483, 484.
This article gives the properties of the following disinfectants:
Bleach surface-disinfectant: Dilute household bleach 1/3 cup bleach to 1 gallon of water, leave on surface 6 minutes. Household bleach is sodium hypochlorite - retrieved 2022/05/13, source: https://www.clorox.com/learn/how-to-disinfect-clean-bathtub-shower-with-bleach/
Among disinfectants currently readily available, none is as economical and effective as bleach when properly diluted and applied.
Diluted bleach to 100-200 ppm is recommended (Chen 2020) - see this Online Bleach Calculator from Foodsafe Canada - BC - http://www.foodsafe.ca/dilution-calculator.html - to find the proper amounts of water and bleach to mix.
Watch out: Use cold water when diluting bleach. If your diluting water is hot it will decompose the bleach and may make it ineffective!
Watch out: never mix bleach with ammonia, alcohol, vinegar - you may produce toxic, even fatal gases such as chlorine gas.
Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material.
Diluted household bleach disinfects within 10–60 minutes contact time (see TABLE G.1 below for concentrations and contact times), is widely available at a low cost, and is recommended for surface disinfection in health-care facilities.
However, bleach irritates mucous membranes, the skin and the airways; decomposes under heat and light; and reacts easily with other chemicals.
Therefore, bleach should be used with caution; ventilation should be adequate and consistent with relevant occupational health and safety guidance. Improper use of bleach, including deviation from recommended dilutions (either stronger or weaker), may reduce its effectiveness for disinfection and can injure health-care workers. - U.S. NIH cited at References:
SODIUM HYPOCHLORITE CONCENTRATION & USE (BLEACH) Table G.1 [PDF] - retrieved 2022/05/15 original source: https://www.ncbi.nlm.nih.gov/books/NBK214356/table/annexg.t1/
Quoting in entirety minor edits for clarity [Ed.]
Starting bleach solution
Most household bleach solutions contain 5% sodium hypochlorite (50 000 ppm available chlorine).
Recommended bleach dilution
1:100 dilution of 5% sodium hypochlorite is the usual recommendation. Use 1 part bleach to 99 parts cold tap water (1:100 dilution) for disinfection of surfaces.
Adjust ratio of bleach to water as needed to achieve appropriate concentration of sodium hypochlorite. For example, for bleach preparations containing 2.5% sodium hypochlorite, use twice as much bleach (i.e. 2 parts bleach to 98 parts water).
Available chlorine after dilution of bleach
For bleach preparations containing 5% sodium hypochlorite, a 1:100 dilution will yield 0.05% or 500 ppm available chlorine.
Bleach solutions containing other concentrations of sodium hypochlorite will contain different amounts of available chlorine when diluted.
Bleach Contact times for different uses
Disinfection by wiping of nonporous surfaces: a contact time of ≥ 10 minutes is recommended.
Disinfection by immersion of items: a contact time of 30 minutes is recommended.
N.B. Surfaces must be cleaned of organic materials, such as secretions, mucus, vomit, faeces, blood or other body fluids before disinfection or immersion.
Botanical disinfectants: Review the manufacturer's specific instructions for contact time for effective disinfectant using a botanical product
To sanitize:
Pre-clean heavily soiled surfaces.
Hold container 6-8” from surface and spray until thoroughly wet.
To sanitize hard, non-porous, non-food contact surfaces*: Apply product. Let stand 10 seconds. Wipe clean with a damp cloth.
To sanitize hard, non-porous, non-food contact surfaces for 24 hours*: Apply product. Allow to air dry without wiping. Reapply if surface is scrubbed.
To sanitize soft surfaces*: Apply product and let stand for 60 seconds. Let air dry.
To disinfect bacteria & viruses: Pre-clean surface.
Hold container 6-8" from surface and spray until thoroughly wet.
For bacteria*, let stand for 60 seconds. Wipe with a cloth.
For bacteria, viruses and fungi**, let stand for 5 minutes. Wipe with a cloth.
To kill the virus causes COVID-19, spray Microban 24 Sanitizing Spray on a hard, non-porous, non-food-contact surface and allow it to remain wet for 60 seconds. Let the surface air dry without wiping.
*When used as directed, effective against Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella enterica, Escherichia coli 0157:H7, Enterobacter aerogenes, Listeria monocytogenes, Methicillin resistant staphylococcus aureus (MERSA), and streptococcus pyogenes.

Excerpts:
For disinfecting non-critical devices/medical equipment and other surfaces:
Spray/apply Cavicide directly to surface, thoroughly wetting area to be disinfected.
(Visibly soiled surfaces should be pre-cleaned.)
Allow surface to remain wet for 2
minutes. ( FOR TUBERCULOCIDAL ACTIVITY: Allow surface to remain wet for 10
minutes at room temperature (20'C).)
Follow by wiping surface with a fresh, clean,
paper or cloth towel; or rinse and either allow surface to air dry or wipe rinsed surfr.lce
dry using a fresh, clean, paper or cloth towel. Discard towel.

Cavicide completely inactivates the HIV-1 (AIDS virus) on hard, non-porous surfaces
in the presence of a moderate amount of organic soil (S% blood serum) with a contact
time of 2 minutes at room temperature (20-2S'C) .
Quats, at 200 ppm or less do not require rinsing. Follow the manufacturer's instructions. (Chen 2022)
Hot water as disinfectant: For objects that can be immersed in hot water at 77°C or above, immerse for no less than 45 seconds. (Chen 2022)
Iodine: at 25 ppm may be used for surface cleaning; follow the manufacturer's instructions. (Chen 2022)
Hydrogen peroxide can damage some items such as cellphones, and may react with bleach to produce dangerous chlorine gas.
Vinegar's disinfectant properties:
Health Canada on Vinegar,
also see David Suzuki's Foundation & "Does Vinegar Kill Germs" - https://davidsuzuki.org/
Excerpt: Acetic acid (a.k.a. white vinegar) can act as a disinfectant that can destroy some bacteria and viruses.
There is no scientific evidence or studies that show vinegar kills a virus like COVID-19.
Household natural sanitizers like lemon juice and vinegar reduced the number of pathogens to undetectable levels.
Vinegar can inhibit growth of and kill some food-borne pathogenic bacteria. Plus, vinegar’s bactericidal activity increased with heat! (Salt helped, too.)
“The combined use of vinegar and sodium chloride, with use of an appropriate treatment temperature, was found to be markedly effective for the prevention of bacterial food poisoning.”
Household disinfectants — vinegar and baking soda used on their own — were highly effective against potential bacterial pathogens but less effective than commercial household disinfectants.
Note: Health Canada states, “Products such as tea tree oil, baking soda, vinegar, electrolyzed water, microfibre cloths, ozone, and silver compounds are not registered disinfectants for food premises, according to the Health Canada definition.”

Ineffective or Improperly-Used Products Sold, Promoted, as Surface Disinfectants
Ammonia (NH3), or ionized ammonia (NH4), a very widely-used cleaning product, is not a disinfectant, though ammonia is used in the production of "Quats" or QACs - quaternary ammonium compounds that are used as a disinfectant in many applications. Ammonia is widely used in household cleaning products including window cleaners, in part because mixed in water it both assists in cleaning and because it evaporates quickly.
Windex glass cleaner, one of our personal favorite glass and marble countertop cleaners, is also not a disinfectant, though its manufacturer, SC Johnson does provide other products that are used as surface disinfectants and cleaners.
Other products such as tea tree oil, baking soda, vinegar, electrolyzed water, microfibre cloths, ozone, and silver compounds are not registered disinfectants for food premises, according to the Health Canada definition. (Gaulin 2014, rev)
Watch out: the guidelines and purposes of cleaning or disinfecting building surfaces and the products suitable for use on building surfaces are quite different from those used to disinfect produce - things to be eaten by people or other animals.
Examples of such disinfectants taht are NOT safe for use on foods include concentrated bleach, rubbing alcohl, ethanol, quat-based cleaners, or Lysol.

Overview excerpts: Nearly all public facilities – such as schools, parks and office buildings – use a substantial amount of surface
sanitizing and disinfecting products while cleaning their restrooms and other public spaces. These products are
inherently toxic, as they are formulated to kill living organisms.
As such, the U.S. Environmental Protection
Agency (U.S. EPA) and California Department of Pesticide Regulation (CA DPR) register all surface sanitizers
and disinfectants as pesticides.
Although all of these “antimicrobial” products have risks, there are a few types
that pose greater, long-term risks to custodial workers and building occupants because they contain active
ingredients that have been found to cause asthma (e.g., chlorine bleach/sodium hypochlorite, peroxyacetic acid,
and quaternary ammonium compounds), cancer (e.g., ortho-phenylphenol), skin sensitization (e.g., chlorine
bleach, pine oil, and thymol) or other health hazards.
Several also pose environmental risks as well, such as
silver and quaternary ammonium chloride compounds.
Surface sanitizers and disinfectants with more benign health and environmental impacts are available and often
have equivalent or greater efficacy.
However, these products have been difficult for purchasers to identify
because US law prohibits the use of ecolabels on EPA-registered pesticides, and because of the complex
nature of the problem; that is, consideration must be given to efficacy against a variety of pathogens, as well as
factors such as surface compatibility and dwell time.

A review of alternative antimicrobial
agents reveals the need for
standardized methodology for efficacy
testing as well as considerations of
toxicity, safety, cost, ease of use,
availability, storage, and applicationspecific testing.
The appropriateness of alternative
antimicrobial agents, such as vinegar,
lemon juice, and baking soda appear to
be limited for commercial disinfection or
sanitization, but some emerging
technologies such as ozonated water

demonstrated substantial antimicrobial
properties.
Agents such as tea tree oil may
demonstrate notable antimicrobial
efficacy, but toxicity and lack of testing
on hard surfaces limit their applications
for hard surface disinfection.
