Glass bottles are common containers in our daily lives, whether they are bottles for beverages, food, or cosmetics. Regular cleaning is necessary to ensure hygiene and reuse. So, how should glass bottles be cleaned?

First, empty the glass bottle after use and pour out any remaining contents. If there are stubborn residues, you can rinse the bottle with a moderate amount of warm water to dissolve and remove the residues.

Next, you can choose to clean the glass bottle using dish soap or a cleaning agent. Pour a suitable amount of dish soap into the bottle, and then add warm water. Use a cleaning brush or sponge dipped in foam to evenly scrub the inner walls of the bottle, paying attention to cleaning the bottle neck and cap. Repeat the cleaning process several times until the inside and outside of the bottle are clean.

For stubborn stains such as tea or oil stains, you can consider using bleach powder or vinegar to clean. Mix water with bleach powder or vinegar in the proper proportion, then pour it into the glass bottle and let it sit for a moment to remove the stains. Rinse thoroughly with clean water to ensure that all traces of bleach powder or vinegar are removed.

After cleaning the glass bottle, it needs to be thoroughly rinsed. Use running water or repeatedly fill the bottle with water and pour it out to rinse the inside and outside of the bottle, making sure there are no residues of cleaning agents. Keep rinsing until the water runs clear.

Finally, invert the clean glass bottle to air dry. To prevent bacterial growth, it's recommended to place the bottle upside down to allow water to evaporate and the bottle to dry naturally. Alternatively, you can use a clean towel or tissue to dry the glass bottle completely before storage or reuse.

In conclusion, when cleaning glass bottles, remember to empty any remaining contents, choose a suitable cleaning agent, thoroughly scrub and rinse, and allow the glass bottle to air dry or dry with a clean towel. Keeping glass bottles clean and dry not only ensures hygiene but also prolongs their lifespan.
