Do UV phone cleaners work???

I was interested to see if UV phone sterilizer cleaners actually worked to kill bacteria so I got some petri dishes and found out. Turns out they actually seem to work.

We use 70% alcohol wipes we get from my wife’s job and clean the phones thoroughly dialy and it won’t ruin your phone screen like Lysol or Clorox wipes will. I’m not gonna trust a electronic device with my families life.

[@AtomicSymphonic]

I'm shocked! They actually work! Essentially, you'd just need to run two cycles per device: One cycle with a smartphone front facing upward, and then a second cycle with the back of the phone facing upward. Flipping it like a pancake. This is perfect. Thank you so much for taking a scientific method to testing whether these devices worked!

[@SnareMan]

I know. I was a little surprised too. it was a fun experiment to do.

[@ismata3274]

In between those two, you need to run it empty one cycle to decontaminate the surface the backside was touching, namely the bottom Otherwise you just contaminated the recently decontaminated front side of the phone. So basically, in about ten minutes and with 3 steps, it's done! Edit: w.hen you take the phone out after the first cycle, you put the phone as is on a paper towel etc... and cover the clean upfront with something clean while waiting the device to decontaminate itself.

[@rachelcaudill1866]

The instructions that came with it recommended flipping over and running a second cycle to get both sides

[@darleneminor1087]

Exactly the post I made, my instructions said to flip over for fully clean. I found one on clearance for $10, mine doesn't have the fancy top that does wireless charging. So if people are interested they do work and are down to $10 at Walmart the brand is Phonespa

[@dariusq8894]

I have a similar type of device manufactured by Lumin specifically for CPAP accessory cleaning. The device has a larger chamber which is mirrored on the inside and includes a clear stand which keeps any articles raised up so the UV light can shine all over for the 5min cycle. Admittedly this device is more expensive (about $250CAD) but because of the larger capacity allows for more varied sterilization (around the size of a shoe box). Additionally, because it was sold for CPAP sterilization purposes the cost is partially covered by health insurance.

I think this one is "Near UV"(405 nm) which is enough to inactivate diverse types of bacteria. This is also the type of light present on most "UV Led sanitizers" online. Actual UVC bulbs are expensive and uses quartz glass in contrast to plastic where "UVC LEDs" use.

just a tip! if you wrap the bottom, top and sides inside the phone cleaner with a reflective material, (aluminum foil, steel, foil tape) it would increase the coverage of the UV light because it will bounce back all around the refelctive material thereby increasing disinfection coverage. and another thing is to put some small anti-slip rubbery feet that sticks, you can stick in in the bottom part to elevate the phone and allowing more reflected UV light to penetrate at the back of the phone.

[@raphaelsalgado8970]

Thanks for this video. I think many people would agree by now that UV cleaners work in general, but since there are so many of them out on the market now, the bigger questions at this point are - does a particular version work (i.e. does it have the right wavelengths, how strong is the light how much exposure time is effective enough for the device's intensity? Also, the ozone generator is a big plus, which I thought you should've mentioned more, as not too many other UV cleaners include that feature.

[@ginta_san]

405nm is enough to inactivate bacteria, keyword "Bacteria". Most cheap "UV Sanitizers" have this. Germicidal UV (UVC) on the other hand, can inactivate viruses and are more expensive and requires a quartz glass to work.

[@prime6965]

I appreciate the science for this! I do wonder though if leaving the petri dishes in a non-sterile environment could have affected the results. I don't think it's out of the question that some bacteria living in water droplets in the air could have penetrated into the petri dishes. There's a reason in the lab petri dishes are kept in a controlled environment, usually an oven-like device.

[@SnareMan]

Could be, but I didn't have a hood or sterile environment at home

[@jeffreyholicky4303]

Thanks for the video. All of them had bacteria remaining. The question though isn't how much can it clean, but how much (left) is enough to cause issues? A single blueberry in a bag that is covered in mold is enough to spread through the whole bag. If I wash my hands with water v. water & soap will water alone be adquate? Many comments say it works - I say it definitely is killing some bacteria (and in the scenario at 7:03 did something really weird) but as per other articles from scientists/professors I have read - the consumer units are inadequate to really do the job properly and that was demonstrated here. IMO (as per Breaking Bad) "Half Measures"/false hope. Thumbs up because you provided empirical evidence instead of a "what's up gang here is my review of something I know nothing about". I bought an S20 FE that comes with the Fit 2 watch or their UV cleaner with charger. The watch is so so and may have limited use. The UV cleaner alone is not compelling but the charger piece does offer a longer life usage.

[@Progsv10S]

It's completely normal that some level of bacterial remains. The Phonesoap doesn't make any claims about sterility, hence the "99.99%". The 99.99% is a marketing claim to say that the device kills ALMOST all bacteria. Snareman's micro tests bare this out. Purell hand sanitizer makes the same claim, but we don't let that stop us from using it. What you're paying for in this case are technology and convenience. If you find more peace of mind wiping your phone down with an alcohol wipe instead, go for it. But that won't eliminate 100% of all bacteria on the object you're cleaning. I like the convenience of dropping my phone into a box for 3 - 10 minutes and being done with it. It's nearly impossible to produce a 100% sterile object in an open environment.

[@catherinepellicer3476]

I have a uv nail lamp and I'm wondering if that would work instead of buying a box. I realise the uv light from a nail lamp is spread a bit more since it's an open space but it could still be quite close to the phone. Thank you for testing the box it does make me more confident about buying a box if the lamp doesn't work!

[@SnareMan]

I don't know. The box also creates ozone which helps with the sterilization and I'm sure the UV nail lamp does not
