Effective on any part that the rays will reach but UVC rays will start to degrade anything that’s plastic over time. Discolouration will be apparent if done enough times.

Not sure what your point is…

Everything that I posted, as @Neithan said, was accurate over a month ago.

I made no predictions and I only stated facts.
 
You can dig up some older stories from last year…Chinese school children severely burned by these in classrooms. ☹️

Makes we wonder what was going on then.
 
That is a great use of the technology you have been discussing if it has been tweeked right or is being used during cleaning and sterilization

President Trump tests negative for the virus…phew. 🙏
He did come very close to those Brazilian officials.
Wow!

The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05-0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective.

Data obtained with benzalkonium chloride at reasonable contact times were conflicting. Within 10 min a concentration of 0.2% revealed no efficacy against coronavirus whereas a concentration of 0.05% was quite effective.

It seems Chlorox or Lysol wipes won’t instantly deactivate (“kill”) the viruses that are similar to the one in this current outbreak. It appears one has to wait for a period of time for the liquid in the wipes to do their job.

The same mixture of bleach and water for cleaning kitchens at home could be better.

Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents - PubMed

Currently, the emergence of a novel human coronavirus, SARS-CoV-2, has become a global health concern causing severe respiratory tract infections in humans. Human-to-human transmissions have been described with incubation times between 2-10 days, facilitating its spread via droplets...

I use bleach at work on surfaces.
Only just learned the surface should be wet for 3 minutes and to mix it with cold water and no soap
 
It states for metal surfaces 5 days. However this paper is based on MERS = Middle East Respiratory Syndrome; HCoV = human coronavirus; TGEV = transmissible gastroenteritis virus; MHV = mouse hepatitis virus; SARS = Severe Acute Respiratory Syndrome; RT = room temperature.

Conclusions

Human coronaviruses can remain infectious on inanimate surfaces for up to 9 days. Surface disinfection with 0.1% sodium hypochlorite or 62–71% ethanol significantly reduces coronavirus infectivity on surfaces within 1 min exposure time. We expect a similar effect against the SARS-CoV-2.

Thanks for the info…

I wiped a bunch of surfaces with Clorax spray. Maybe not strong enough, definitely not on for long enough, and I think it is mixed with soap 😦

This is good. Most hydrogen peroxide sold in the stores (in brown bottles) is 3%, so you could do 5 parts water : one part hydrogen peroxide 3% and still kill the viruses.

And not have to breathe in all that Clorox!

Soap and bleach should not mix.

It looks like the issue is people have to wait for the cleaner to deactivate the virus.

I have never used hydrogen peroxide to clean at home before.

Unfortunately, I haven’t seen any studies with the actual virus yet.

Experts are quoting much longer here.

At this point there has been no studies on COVID-19/SARS-CoV-2 longivity on surfaces - they are old studies that have reviewed:

MERS = Middle East Respiratory Syndrome;
HCoV = human coronavirus;
TGEV = transmissible gastroenteritis virus;
MHV = mouse hepatitis virus;
SARS = Severe Acute Respiratory Syndrome.

So 5 days survival on metal is for the five listed above - the detailed paper I posted states this and (original from ATraveller) does not mention COVID-19/SARS-CoV-2 as being tested.
