Putting PhoneSoap to the Test: an Outsider's Perspective

Putting PhoneSoap to the Test: an Outsider's Perspective

"Does PhoneSoap really work?" 

We get this question all the time. With no visible evidence, it's hard to tell. Our short answer is YES, but you don't have to take our word for it. We aren't the only ones who've tested PhoneSoap products to see exactly what they can do. 

First up . . .

1) MacSources

You can read their full review here, but I've included the highlights below:


"I had the director of a local laboratory swab the screen of my iPhone XL and the back of my Speck Ultra Presidio case with sterile swabs. I then placed my iPhone X into the PhoneSoap 3 and patiently awaited the 10 minutes. At that point, the lid was opened, the front of the iPhone X was swabbed, and then the sides were gripped, and the back was swabbed. The pre-UV cleaned samples were not as spectacular as those seen before the HomeSoap testing.  However, neither of the post-UV cleaned specimens had any bacterial growth.  Similar to the experiment with the HomeSoap, the PhoneSoap 3 did not disappoint."
Here are his results:

2) Delmarva Life

This one is cool because you can see the process in which a lab technician swabs the phone and incubates the Petri dish. 

3) KHOU*11

This is a news station based in Houston, Texas. News anchor Tiffany Craig visited a lab at Rice University, and with some help from biosciences professor Dr. Matt Bennett, discovered that UV-C light does exactly what PhoneSoap promises. Here is a photo of their results.

4) ThioJoe

This YouTuber reviews all things tech. He ordered a few Petri dishes and conducted the experiment right at home.

5) DadLogic

This thorough review is awesome because the author tests more than just his own phone. He also conducted his own experiment at home and gets awesome results, like the one below.

"In the photo above, you can see the before and after the result. The top Petri dish is the 'before' and shows a few different types of bacteria. (I let it incubate for 72 hours). The bottom dish shows how much of a difference one sanitation cycle can make. The dish has hardly any growth, which is impressive when you consider that the swabs were taken just five minutes apart."

    Hello! I would love to see these experiments done using 16S rRNA sequencing or some other sequencing-based experiments. As we know, a huge portion of bacteria are not culturable, so some sequencing of swabs would be more convincing to me. As someone who works in a microbiology lab, I am well aware that UV-C light can kill bacteria (we use UV cross-linkers in our lab all the time). However, what I am not yet convinced of is how powerful these particular bulbs are. I know the cultured agar plates are much more sexy looking than sequence data, but I think it would be great to add sequence evidence as well

    What wavelength do this operate at?

    Hello! I was wondering if the sanitizing results I have been reading/watching videos of pertain to all your phone soap products – including the ones in the $50 range? Many thanks! I’m looking at getting these as gifts for my entire family – if they actually work.

    Hi Mary!

    Great question – our consumer devices like the PhoneSoap 3 is germicidal so it kills germs in general. Because it is a consumer device, we’ve tested it against common household bacteria and virus. Since C. Diff is mainly a problem encountered in healthcare environments, we don’t test our consumer devices against it. We do however test our devices intended for healthcare against it – check out the PhoneSoap Med!
