Is it true that the arrows smartphone is dirty than the toilet seat !? Gachi verification with "arrows Be4 Plus F-41B"

Investigate dirt on your smartphone and toilet seat during the tray!

It has been said for many years that "smartphones are more dirty than toilet seats." It is true that smartphones are touched almost all day long, and human hands often touch various parts of human parts, such as grasping, pushing, and grasping. However, alcohol disinfection is frequent these days, and can it be more dirty than the place where it is used in the first place? Suddenly, the author, who came up with such a thing in the bathroom, decided to stay home and verify it during Obon.

However, it is difficult to understand vaguely "dirty" and "beautiful", so we need a tool that can convert dirt into data as numerical values. Therefore, I consulted with FCNT, who is working on the washable smartphone "arrows" series and is particular about the cleanliness of smartphones. "I want to find out if my smartphone and toilet seat are really as dirty, so please lend me a tool that can visualize the dirt!" And when I made an unreasonable request, I was immediately sent an inspection kit. It's called a smartphone disassembly project, and FCNT's good taste ...

By the way, I borrowed the "arrows Be4 Plus F-41B" (the price of the DoCoMo online shop is 21,780 yen) released as a summer model by DoCoMo as a verification smartphone, and tried it for about a week. And the inspection kit is Kikkoman's "Lumitester PD-30". Speaking of Kikkoman, seasonings and oolong tea are famous, but I did not know that such a test kit was also released.

As a result of sticky touches such as playing games and SNS for about a week, it can be seen that the display is dirty with the oil of the hands.Obviously dirty at this point

Fingerprints are hard to get on the back, but it still has sebum (it may be hard to see in the photo).Since the palm of your hand hits the back, it is easy for hand sweat to adhere to it.

The result is displayed on this LCD screen. If 3000 is the standard value and above this, it fails.

There are liquid and powdered chemicals in the first place

And if your smartphone is dirty, you have to wash it. I also borrowed a "hand-washing checker" to check if the details can be washed thoroughly. This is because if you apply a special lotion, wash it, and then apply a special light, the lotion that has not been washed off will react and shine. If the lotion is shining, it is proof that it has not been washed at all. This time, using the arrows Be4 Plus F-41B after checking for dirt, I also verified how clean it would be if washed.

The special gel reacts to this light and shines. Note that it is dangerous to look directly at the light!

For shock inspection results!The smartphone was so dirty

Now let's inspect for dirt. First of all, from the smartphone arrows Be4 Plus F-41B. There is a cotton swab in the dropper-shaped case, so moisten the swab with water and then rub the part you want to inspect. After that, return the cotton swab to the case, push it all the way in, and shake it in that state to mix the chemical and liquid. All you have to do is put the case in the Lumitester and press the "Enter" button. The result is displayed in 10 seconds.

Lightly moisten the cotton swab with water.

Shake lightly multiple times

I got the result! At 4760, it far exceeded the standard value of 3000.I was so depressed that my hands were so dirty

Check the toilet seat by the same procedure. As expected, the hands that touch the smartphone are not dirty than the buttocks! I felt like I could afford it ...

Rub the toilet seat with a cotton swab

The test result is ... 4718! Is your smartphone really as dirty as a toilet seat?Rather, it was a shock that the toilet seat was cleaner than the smartphone

As mentioned above, it was proved that both the smartphone and the toilet seat were just as dirty. I wash my hands every day and disinfect them with alcohol ...

Speaking of which, children often touch various places and their hands get dirty when playing outside, so the numbers are quite high, right? I thought, I decided to do an additional test with the tablet I gave my child.

It's a little difficult to understand, but it looks more dirty than a smartphone.Rub the dirty part with a muzzle and a cotton swab

The number is 3908. Although it failed, it was cleaner than a smartphone or toilet seat. The child's hands seem to be dirty no matter what.This is probably because smartphones are used less frequently than tablets.

Numerically prove how clean your smartphone will be if you wash it

From the results of the previous experiment, it turned out that the toilet seat and the smartphone are just as dirty, but it should be remembered that the arrows Be4 Plus F-41B is "washable". Use a hand-washing checker to verify how much dirt can be removed by actually washing.

It will be like this when washed away. Lotion remains in some places, and you can see that it cannot be washed well.I sometimes use this equipment for hand-washing training at restaurants

Nana, how 31! To a level like new and unused!

I was able to prove numerically that washing the smartphone makes it much cleaner. I hope you understand the importance of washing your smartphone. After all, it's better to wash it than not to wash it, and above all, it feels good to use a shiny smartphone.

When you touch your smartphone, you may get cosmetics on it. You may touch it while eating sweets. If anything, it could be dropped in the bathroom. Various things are attached to smartphones only to the things that modern people touch most. However, I want to keep it clean because it is the one that I touch the most.

In that sense, the element of "washable foam hand soap" in the arrows series is very meaningful and attractive. Ordinary smartphones are only waterproof, and cleaning with detergent is not recommended. The number of smartphones that can be washed may increase one after another, but it should be remembered that arrows is the originator of "smartphones that can be washed with foam hand soap".
