According to the New York Post on the 19th (local time), Cabrie (19), who lives in the United States, has suffered from various illnesses since August. She first contracted bronchitis, and just as she recovered, she developed sinusitis (sinus infection). In addition, Cabrie frequently suffered from colds and other minor illnesses.

She then realized that the reason she kept getting sick was because she was not properly cleaning her tumbler. Upon inspecting the inside of the tumbler, Cabrie found that the lid was covered with mold.

Afterwards, she started cleaning the tumbler thoroughly before using it. She reported that symptoms such as colds disappeared. Currently, she is posting videos on social media (SNS) encouraging people to clean their tumblers.

In fact, many people think that tumblers used only for drinking water do not need to be washed, but this is not true.

Various types of bacteria live in the mouth, and during the process of drinking water, saliva mixes with the contents inside the tumbler, creating a high possibility for bacteria to multiply. Also, since tumblers are often held while drinking, bacteria from the hands can transfer to the tumbler.

Therefore, it is recommended to wash a tumbler immediately after even one use. According to a study published in the Canadian Journal of Public Health, streptococcus and other bacteria were found in unwashed water bottles.

Moreover, it is necessary to clean not only by rinsing with water but also by using a brush to wash the inside, outside, and the mouth-contact areas of the tumbler thoroughly.

As in Cabrie’s case, when washing a tumbler, attention should also be paid to the lid. The rubber packing on the lid tends to remain wet from the liquid inside the tumbler, creating an environment conducive to mold growth.

When washing the tumbler lid, soak it in lukewarm water mixed with baking soda, and after about 10 minutes, scrub it with a toothbrush or similar tool to clean it thoroughly.

Especially for stainless steel tumblers, although the structure usually does not undergo a polishing process, if a polishing agent has been used, it is recommended to wipe the inside once with a kitchen towel soaked in cooking oil or boil a mixture of vinegar and water in a 1:9 ratio for about 15 minutes, then wash with a neutral detergent.
