Bacteria On Phone | How To Clean Bacteria From Phone | Germs On Mobile Phone | How Dirty Is Your Phone | Disinfect Cell Phone

Hey all, in this weeks video we visited Dr Isreb at the University of Bradford School of Pharmacy to see what bacteria are on my phone, toilet seat and skin! Watch the full video to see what we found…

Let’s admit it, in this day and age, we go everywhere with our smartphone. It is our friend, philosopher, guide and so much more! We practically live with it 24×7 but how many times do we clean it? Our phone is perhaps one of our dirtiest possessions with bacteria all over it.

Research has varied on just how many germs are crawling on the average cell phone, but a recent study found more than 17,000 bacterial gene copies on the phones of high school students. Scientists at the University of Arizona have found that cell phones carry 10 times more bacteria than most toilet seats.

Human skin is naturally covered in microbes that don’t usually have any negative health consequences, and that natural bacteria, plus the oils on your hands, get passed on to your phone every time you check a text or send an email. It follows that most of the organisms found on phones are not pathogens that will make you sick.

Normally I’m not so anti-bacteria, I don’t believe that we should be killing bacteria all the time as there are such things as good bacteria but in this case sanitise your hands and your phone. But some bacteria should concern you which you can get from simply touching an unclean surface and then transferring it to your phone.

Studies have found serious pathogens on phones, including Streptococcus, MRSA and even E. coli. Just having these microbes on your phone won’t automatically make you sick, but you still don’t want to let them enter your system or someone who has a weekended immune system.

Viruses can also spread on phones if one person is sick with strep throat or influenza and coughs on their cell phone before handing it off to a friend.

Still, the best advice has more to do with you than the phone. Wash your hands several times a day, the experts say, and you’ll likely be just fine.

Here’s a really useful video on how to wash your hands properly by the NHS:

One of the worst places to use your phone is in the bathroom. When toilets flush, they spread germs everywhere, which is how phones end up with faecal bacteria like E. coli. Taking a cell phone into the bathroom and then leaving with it is kind of like going in, not washing your hands and then coming back out, It’s the same level of concern.

We tested both cleaning methods in the lab with Dr Isreb and they were both effective at reducing the bacteria on my phone.

Cleaning Method 1 (Safe Daily Cleaning Method),
Just wipe your phone and buttons with a soft clean microfiber cloth, which will remove many of the germs.

Cleaning Method 2 (Once Weekly Deep Clean),
I’ve started to use this his method once a week and it hasn’t damaged my phone. Please note however it may damage the protective coating on your screen so do it at your own risk.

What you will need:
• Bottled water or distilled water
• 70% isopropyl alcohol
• 1 Mini spray bottle
• 1 Clean microfiber or lint-free cloth

Step 1: Fill a spray bottle halfway with distilled or bottled water.
Step 2: Fill the other half of the bottle with 70% isopropyl alcohol.
Step 3: Screw the cap back on and shake the bottle to mix the solution.
Step 4: Lightly spray the solution on a clean microfiber cloth and rub it all over your entire phone — especially those buttons!

    Wow! I did not realise how dirty our phones actually could be!! I know some people who use theirs in the toilet so I will be sure to pass this video on. I love the documentary style video. It’s a fantastic video yet again. I always look forward to 4pm every 2 weeks to see your videos. Also I am definitely going to start cleaning my phone more often than I do!! Keep the videos coming 👏🏻

    "Some people actually use their phone in the toilet". Literally everybody uses their phone in the toilet.

  15. KegPatcha on September 6, 2021 at 10:42 pm

    Taking the fucking phone to the bathroom is the source of all my diseases. Mieda, mierda!!! Esta fue la causa de mis enfermedades. La mierda!!

  16. Mr Chill on September 6, 2021 at 10:42 pm

    Thanks Abraham this is so relevant now of all times !!!

  17. Julianne H. W on September 6, 2021 at 10:42 pm

    sorry for being late but hope you know that washing your hands does not mean by only have water haha

  18. Philip JACKSON on September 6, 2021 at 10:43 pm

    My relationship has been a problem too me for the past two years now, my husband came up with an attitude of not having my time, he always smile to the screen of his phone, each time I try to come close he will stop what his doing, and this shirt get me so worried, I told my friend kelly on Instagram she introduced me too KIRYEHACK on Instagram, After I provide some basic data that he wanted, kiryehack on Instagram was able to get me into my fiance’s account. Now I’m able access everything including deleted message, I find out he was cheating and he have a baby😭😭 with another, I don’t know what too do right now 😭😭

  19. Celestial_VirtueYT on September 6, 2021 at 10:45 pm

    I’ll admit I do bring my phone into the toilet, but rarely

  20. Sumithra R K on September 6, 2021 at 10:45 pm

    I will use sanitizer twice a week to clean my phone

  21. Dakota Matos on September 6, 2021 at 10:48 pm

    It’s really dangerous to touch someone’s hands. This is why I use hand sanitizer, and why I don’t touch either humans or phones (besides my own).

  22. dongoggine on September 6, 2021 at 10:48 pm

    I got a waterproof phone , I wash it everyday with soap. It’s so clean you could eat off of it.

  23. Marvellous STD on September 6, 2021 at 10:50 pm

    1:06 "I’m really excited about this but also a little nervous as to what you’re gonna find"

    OMG I love this

  49. Miriam Camilleri on September 6, 2021 at 11:15 pm

    Hi Abraham, being a biomedical scientist this struck a chord with me and I couldn’t help noticing that the inoculated Petri dishes were unlabeled. The label lay on the paper underneath. How could anyone be so sure there were no mix ups in the process? I am accustomed to label the Petri dish base itself, as since the cover is exchangeable does not rule out a mix up. It is very important to label each case at every stage of the testing and documenting every step and finding. Thanks for your creative and informative videos. And the humorous bloopers, naturally!, lol!

    Good job comparing our phones with toilet seat! hardly held on to mine through the video! 😰😂
