Some coronaviruses can linger on surfaces for up to 9 days
... how long can the new coronavirus linger on surfaces, anyway? The short answer is, we don't know. But if this new coronavirus resembles other human coronaviruses, such as its "cousins" that cause SARS and MERS, it can stay on surfaces — such as metal, glass or plastic — for as long as nine days, according to a new study. (In comparison, flu viruses can last on surfaces for only about 48 hours.)
In the new study, researchers analyzed several dozen previously published papers on human coronaviruses (other than the new coronavirus) to get a better idea of how long they can survive outside of the body. The authors found that these coronaviruses can linger on surfaces for over a week but that some of them don't remain active for as long at temperatures higher than 86 degrees Fahrenheit (30 degrees Celsius). The authors also found that these coronaviruses can be effectively wiped away by household disinfectants.
For example, disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can "efficiently" inactivate coronaviruses within a minute, according to the study. "We expect a similar effect against the 2019-nCoV," the researchers wrote,

I think it’s relative.
It might survive for an hour and a half at 30 degrees, but much shorter at 40 degrees.
Like, maybe 25 minutes. Those times are completely out of thin air, BTW.
I don’t know the actual times, but it does survive even at high temperatures, but got shorter and shorter lengths of time as the temperature increased. And the humidity grew over 60% or so.
20 degrees it was pretty stubborn.
My understanding is all.
Could be wrong.
The fibers in the fabric and wood wick away the moisture from the protective coating and it drys out and destroys it. On tissue paper the typical flu virus lasts only 15 minutes.
Check out post 19 for some really good information (hat tip to PA Engineer). Lysol works - active ingredient is hydrogen peroxide. Alcohol works too. A month ago, every trip to Costco I would get four bottles of each. (And toilet paper, etc.) Every time I went back they had plenty - so figured I wasn’t causing a problem with my buying habits. I haven’t been back in 2 weeks, so I have no idea what is going on now.
Note the various times that the stuff has to be in contact with the virus. I heard that the Clorox wipes have to wet the surface for 4 minutes, but based on the paper in #19 that seems too long. (I forget which ingredient the Clorox wipes are - Benzi*** something!!??
Check out ozonators and UVC. You can decon a room with ozone. For small surfaces items, a UVC device will also work. I’m still working on times and mg/hr ozone rates.
Right when this thing started I bought an O3 machine and two UV lamps. (Perhaps you had mentioned them?) A week later I figured I would get a UV light for each of my kids. They had doubled in price. A couple weeks ago I looked to see what their latest price was. Oops - now they are on back order.
I am sure 91% alcohol will do it. Just do not breath it (or use near flame, obviously).
I read of a study in which wooden surfaces had less bacteria then their modern plastic replacements after being cleaned with the same bleach. It was surmised that wood itself is mildly antibacterial. Bleach likely remains longer on it also.
Until the Lysol or bleach hits it.
To a virus fabric is like the Himalayan Mountain Range. Stainless Steel surfaces keep the ‘family’ close and interconnected.
Don’t forget to mention that while there appears to be under 100K cases world-wide 9so far), the average Flu season catches about 30 Million Americans even though we have “vaccines”...
Unless coronavirus has a sudden huge surge, I find that comforting.
So is there a risk from items shipped from China to the US?
If that were remotely true, it would have died out long before anyone contracted it.
No. Read the op for what kills it.
Lysol says on the bottle/can it can eliminate “Human coronavirus” but this is not that virus. It is in the same family but it not the same. Bunny rabbits are in the same family as lions. Both are mammals. Which would you not mind so much coming into your house? Same idea as all the various coronaviruses. This one is the lion when talking mortality rates.
The big spraying trucks in China are using bleach. Read the op for what helps to kill it.
Yes. However, it depends on how many days it takes between being off loaded in the US and it gets to your front porch.
However, not much is being shipped these days and if it is countries aren’t accepting the cargo or even allowing the ships to dock. Of course, the US is allowing cargo planes to fly back and forth stopping in Alaska to refuel.
Many factories in China were shut down until the government decided that wouldn’t be good for the market (always the market these days and not the people) so are opening back up. Basically, if you can walk you will return to work until you fall on the floor and they drag you away and replace you with the next walking dead.
I can buy bleach & Hydrogen Peroxide...\
BUT WHERE does a person buy Ethanol?
Rubbing alcohol refers to either isopropyl alcohol or ethanol based liquids, or the comparable British Pharmacopoeia defined surgical spirit, with isopropyl alcohol products being the most widely available. Rubbing alcohol is undrinkable even if it is ethanol based, due to the bitterants added.
thats’ absolutely true for food cutting boards... always go with wood! The plastic kind don’t even get truly clean in a dishwasher... because of gouges in the board you can and can’t see... bacteria can hide.
