If you must use both to maximally remove infectious organisms from the hands, it's best to wash hands with soap and water, dry, then apply hand sanitizer and allow to air-dry on the skin. This is because dirt, food, oils, etc. on your hands can make the sanitizers less effective. If you first wash your hands to remove barriers to their effectiveness, the ...

In most isolation cases, the actual order isn't going to matter, since the typical isolation area that you would be allowed to enter isn't for the patient's benefit, but other people, so that they don't catch what the patient has. In this case, it doesn't matter which order you put it on. (Especially since they are being stored in an area where anyone ...

You should read the whole article: Things You Should Never Microwave ... - Clothing and other large fabric items The problem with microwaves is that they are not heating any item put inside them homogeneously but create "hot spots" instead. The image shows a simulation of the electric field inside a microwave oven (taken from wikipedia). Therefore, ...

Dettol upon contact with H2O turns milky like white. When H2O is added to the dettol liquid its oil droplets become suspended in the water droplets, creating something called an Emulsion. It is that state of emulsion that causes the colour to change with its response to light.

To add to Philipp Leitl's good and cautionary answer: Microwave ovens work by causing polar molecules in the food being cooked, e.g. water and fats, to rotate, according to: Why does microwave heat up things so much more quickly than visible light? This rotational movement provides the heating effect. I would not be sure that the chemical make-up of ...

The text does not say that more diluted bleach is more effective at killing viruses (or bacteria, or yeast, for that matter). I'm quoting: ...A tenfold dilution of bleach, which subsequently mixed with an equal volume of RSV-containing medium (so in fact a twentyfold dilution) eradicated all of the virus. A 100-fold dilution of bleach killed 100% of the ...

Household bleach is usually at 5% concentration of sodium hypochlorite. Data from disinfection of other coronaviruses indicates that dilutions of 1:100 are still effective. Higher concentrations of bleach are difficult to manage as they release chlorine gas and are irritant to the mucous membranes, lungs and eyes. The bleach works as a potent oxidizer of ...

It isn't possible to completely sterilize the gut of a living person. Repeat: not possible under any circumstance in a living person. You can dramatically decrease the number of organisms by using high-dose antibiotics and flushing out the gut copiously, and by copiously, I mean your intake plus an osmotic agent is so high that you have explosive diarrhea ...

Edit: COVID and your laundry In April, a Texas biomedical scientist published an article about COVID and clothing. She suggested that, during the COVID pandemic, it's usually fine to just do laundry in the ordinary way. But, if you're washing the laundry of a likely COVID patient, it's wise to take extra precautions. Please see the CDC's recommendations, ...

It is used among humans it's called: Hibiclens, Dyna-Hex, Ezy-tm, and Exidine As also stated by the user JohnP in a comment. And it works for: Cleaning the hands Before surgery or injections To cleanse skin or wounds And as a oral rinse So there is no exception it is used for humans. But you are right it is also used for animals.

In this pandemic it is important to take precautions at each and every step. Fruits and vegetables should be properly cleaned. We don't know of fruit/vegetables vendors, who might be infected with COVID-19.

Outbreaks and pseudo-outbreaks related to contaminated germicides have most commonly been reported with contaminated antiseptics. Outbreaks from contaminated high-level disinfectants have rarely, if ever, been reported. Outbreaks from contaminated intermediate- and low-level disinfectants have occasionally been reported. All outbreaks associated with ...

I can't find the CDC page you allude to, but I suppose you've read something like this: Cleaning, accomplished with soap–or detergent–and water, refers to the physical removal of dirt and grime, and in the process, some portion of the germs on a given surface. Sometimes cleaning tools, including sponges and cloths, simply move germs from one surface to ...

40% alcohol is probably too dilute for disinfection. According to the CDC, minimum concentrations for sanitization with alcohol are 60% for ethanol or 70% for isopropanol (https://www.cdc.gov/coronavirus/2019-ncov/hcp/hand-hygiene.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fcoronavirus%2F2019-ncov%2Finfection-control%2Fhcp-hand-sanitizer.html) .

I don't know but they're likely spraying bleach to kill virus on surfaces. Studies show the virus can persist for days on stainless steel etc, but we don't have good data how much of any of this can cause further infection. It does help to impress on the public the need to keep washing which is the most effective way to be safe apart from complete ...

The latest data suggests virus can be recovered from surfaces at 17 days I suggest spraying everything with a bleach solution which has also been recommended by the CDC. That should disable the virus.

The EPA has a database that you can search for tested effectiveness against SARS-CoV-2 virus. You need to find the EPA registration number of the product you have and check it against their database. Dettol products containing a high concentration of alcohol are thought to be effective as a surface disinfectant ( greater than 70% ethanol/propylalcohol ). ...

The accepted knowledge is that boiling water for 1 minute kills viruses. However, that is not necessary for SARS-CoV-2. Any food you eat is going to be cooked for longer than a minute, and packaging can left for a couple of days for the virus to inactivate naturally. The standard recommendation for boiling water is a FULL ROLLING BOIL for ONE MINUTE and ...

Since methanol had been added the resulting solution is toxic.

In summary, there is no reliable evidence to say that grapefruit-seed extract has any disinfection efficacy. It was found out that some commercial products have been adulterated with artificial disinfectants. Some sources mention that grapefruit-seed extract has been used in hospitals in the United states; not to prevent/treat skin infections but to ...
