Here are a few reactions after poking around on their website. This seems like an expensive way to sell a relatively simple cleaning solution that is made of citric acid and malic acid. (3/10)
They mention some laboratory testing of E. coli "157" and "Staph", which is not that surprising. They also state they have not registered with the EPA, so they are not legally classified as a sanitizer or disinfectant. (4/10)
They cite the German study that investigated 14 sponges, or as I said when I discussed it on @dobyfriday "14 fucking sponges", which is probably not the right number of sponges for scientific research. (5/10)
They claim that microwaving sponges doesn't disinfect them, but then as support they site that same German study. (6/10)
I still stand by the advice of microwaving your sponges. Just make sure they're wet so you don't start a fire. (7/10)
For those of you lucky enough to have a house equipped with an automatic dishwasher, this is also a great way to sanitize your sponges. (8/10)
Make sure that your sponges dry out between uses, and throw them away and get new ones when they get smelly. (9/10)
I sure would not spend 50 bucks on this device, nor would I trust a solution of citric acid and malic acid to control microorganisms. (10/10)

Room temperature thawing of frozen meat is an interesting topic that comes up from time to time. If you check all of the food safety advice websites they will tell you that it is not safe to do this. (1/18)
They will instead recommend that you thaw in the refrigerator, in the microwave, or under running water. (2/18)
I think all of these are reasonable risk reduction measures to take. They were especially reasonable when we didn't really know anything at all about transmission of COVID-19. (2/8)
Having spent the past few months thinking about this and reading the rapidly expanding literature my position has changed over time. (3/8)
Today a reporter asked me a bunch of questions about disinfectant wipes. I thought it might make a nice tweet thread. (1/28)
You may have also heard a certain elected official who is making disinfectant recommendations that were not exactly based on science. Questions and answers below. (2/28)
—What is the difference between disinfectant wipes and antibacterial wipes? (3/28)
I've been meaning to post a thread talking about COVID-19 transmission that breaks down my current thinking on the topic. This is that thread. (1/25)
By far most of the cases seem to be from direct person to person transmission from individuals who are symptomatic (i.e. sneezing and coughing)... (2/25)
with a smaller number of documented cases of transmission from people who are pre-symptomatic (i.e. not sneezing and coughing, but who will manifest symptoms later because they’re already infected). (3/25)
I answered a similar question from a reporter earlier today. Here's a brief tweet thread on UV devices: (1/6)
How does UV light work to kill bacteria and viruses? UV light works because it damages the the DNA or RNA of microbes. If you damage to enough of the nucleic acid the bacteria die or the virus cannot infect. (2/6)
Which kinds of surfaces does UV light work best on? It works best on smooth surfaces. If a surface is rough (even at the microscopic level), bacteria and viruses can hide in the valleys in the shade so that they are not hit by the UV rays. (3/6)
Hey folks. It's a good thing that I'm almost off Twitter these days, otherwise I would be spending way too much time there. (1/22)
Occasionally I get email messages from normal folks who have questions. I thought it might be fun to share some questions and answers. I fixed a few typos, but otherwise the questions are as presented. (2/22)
Apologies if some of this rehashes earlier messages, but I continue to evolve my thinking and communication on the subject. (3/22)
