How to clean a new water cup for the first time

In our daily lives, we should all use cups as containers to drink water. However, when we buy cups and take them home, we find that most new cups actually have a smell. Therefore, before using a new water cup, you should clean it before using it. In fact, there are many ways to clean a new water cup. So how should you clean a new water cup for the first time?

The first method: Baking soda odor removal method: Add a certain amount of hot water and baking soda into the cup, mix and stir so that the mixture fully contacts every corner inside the cup, then let it stand for a few minutes, pour it out, and rinse with clean water. In this way, after the cup is dried, the dirt and odor inside will be removed.

The second method: using toothpaste to remove odors: We all know that toothpaste is used to clean the mouth and teeth, but toothpaste can also be used as a cleaning agent to remove odors in the cup. We can clean the inner wall of the cup with a toothbrush dipped in toothpaste like brushing our teeth, then rinse it, and the odor in the cup will be removed.

The third method: using salt water to remove odor. Mix a small amount of salt with water, pour it into a cup, shake it thoroughly, let it sit for a while, and then rinse it with clean water.

The fourth method: Boiling to remove odor: This method requires the cup itself to be heat-resistant. We need to put the cup in tea or water and boil it for about three minutes, then rinse it with clean water.

Fifth method: remove odor from milk. We can pour the leftover milk or the expired milk into a cup, then add warm water and shake well, let it stand for a while, and then rinse with clean water.

Sixth method: Use orange peel (lemon peel) to remove hair odor. This method is to utilize the orange peels (lemon peels) left over from eating oranges for waste utilization. First, we need to rinse the cup, then put the orange peel (lemon peel) into the quilt, seal it and let it stand for one to three hours, then rinse the cup.

When you use a new cup for the first time, you must clean it and remove the odor. This is for the sake of your health.
