Oh, what a great idea!

It has been banned from selling to minors for a long time, mainly because of drug use, if I remember correctly.

Rhaaaa! But everyone knows it because prohibited. :D

I am convinced that the dishwashing liquid (lemon : Mrgreen: ) is more effective than soap.

For its plastic racing packaging? And even the passage with a sponge soaked in pure liquid?
With of course the mapa gloves that were used during the races ...
The revolution is underway ... Everyone is doing the dishes. :)

So why are you talking about it?

Does it have to foam it seems?
For alcohol at 90 ° the virus disappears in 30 s

Is your document also valid for covid-19? (since it goes from 2005 to 2009 ...)

already quoted https://www.journalofhospitalinfection.com/article/S0195-6701(20)30046-3/fulltext#sec3.2
Analysis of 22 studies reveals that human coronaviruses such as severe acute respiratory syndrome coronavirus (SARS), Middle East respiratory syndrome coronavirus (MERS) or endemic human coronaviruses (HCoV) can persist on inanimate surfaces such as metal, glass, or plastic for up to 9 days, but can be effectively inactivated by surface disinfection procedures with 62–71% ethanol, 0,5% hydrogen peroxide, or 0,1% sodium hypochlorite in 1 minute. Other biocidal agents such as 0,05 to 0,2% benzalkonium chloride or 0,02% chlorhexidine digluconate are less effective.

Hello,
I asked an acquaintance for an answer to this question. He is production manager in a French pharmaceutical factory that manufactures millions, among other things, the flu vaccines that are sold in both hemispheres, here is his answer:


"_ to get rid of the virus several possibilities. First of all, the lifespan of a virus outside a host (Animal, Bacteria, cell…) is limited in time unlike certain bacteria whose lifespan even without nutrient can be very long. Basically we leave an object in place and after a while the virus is dead

There is first cleaning as for a stain by a product, use of a detergent which will trap what we clean and make it go to the rinsing (a little like the anti-deposition detergent ;-)). Very useful method for the hands with soap, Detergent with Hot water for the clothes, shower for the body. After to disinfect a surface against the virus, which is not well resistant to the disinfectant, it is possible to use alcohol (advantage leaves no residue on drying) or bleach for surfaces without soiling . For dirty surfaces it is better to use disinfectant detergent which will help to clean and disinfect at the same time (like the floor where there is always dirt)



In the pharmaceutical industry (Best in class) we always clean to have very very clean elements before autoclaving, radio sterilization or other methods we validate our processes to have less than 1 chance in 1 million (probability less than 0.0001 % of having a bacterium on our equipment for the entry of non-stearable material in a clean room, we use airlocks dedicated to the entry of material which is disinfected with disinfectant products (Hydrogen peroxide + peracetic acid, Alcohol, Quaternary ammonium…) ) beware these products are toxic



In a home environment we can never guarantee absence of bacteria and virus but the optic is to say we reduce the microbial and viral load to the maximum because to fall ill it generally takes more than a virus or 1 bacteria except intravenously for drugs where it can be fatal
