How often do you wash mugs?

Office mug is very common and easy to use, whether it is tea or coffee are indispensable, use for a long time will inevitably make the cup difficult to tangle with tea or coffee stains, then you must wash it?

Foreign studies have pointed out that under two preconditions, it is actually more hygienic not to wash the cup.

The first is that cups should be used daily. If left unused for too long, Stark says, the buildup of dirt such as sugar or cream can cause mold.

The second is not to share the cup with others, which does not mean that there are no bacteria on the cup, but most people who use their own cups will not be repeatedly infected by the same cup even if they use the mug when they are sick.

In addition, Stark stressed that the sponge sponge Shared in the tea room was actually dirtier than he thought, and could be worse than a mug left unwashed for years.

Since that is usually the item with the highest number of bacteria in the workplace, it is recommended that you decide whether to wash the cup or not depending on your personal circumstances, or it is safer to take it home.
