Bathrooms are humid, so it’s easy for bacteria to grow on your toothbrush.

If you don’t take care of it, your toothbrush is dirtier than a bathroom toilet.

I will tell you how to sterilize easily.

First,

add a tablespoon of vinegar to warm water and soak for 5 minutes. Vinegar has an excellent sterilizing effect.

Second,

pour an appropriate amount of mouthwash into a cup and soak the toothbrush for about 5 minutes. Mouthwash contains antibacterial and sterilizing ingredients.

Third,

dissolve baking soda in warm water and soak the toothbrush for 5 minutes. Baking soda not only cleans but also has a sterilizing effect.

​Fourth,

dissolve a spoonful of salt in warm water and soak the toothbrush for 5 minutes. The salt content of the salt acts as a sterilizer.
​The results of a study on toothbrush sterilization using bamboo salt, mouthwash, baking soda, and vinegar were announced. The most effective method is soaking in vinegar, and the second is using mouthwash.
