Aside from using your trusted dishwasher to clean your bottle, there are several ways that are also effective in cleaning and sanitizing your bottle. Here are some of the most natural and efficient ways to clean your water bottle.

Warm Water and Soap

Distilled White Vinegar

Distilled white vinegar is a cleaning agent that does not smell so good. However, it can remove the nasty smell and stain on your bottle. All you have to do is to take equal parts of water and vinegar solution. Soak the bottle overnight with the mixture and rinse it with warm water the following morning.

If your bottle still smells like vinegar after rinsing, wash it with hot water and soap. Let the hot water sit there for about 5 to 10 minutes then rinse it out. Allow the bottle to dry naturally before storing or putting the lid on.

Baking Soda

Baking soda is also an effective cleaning agent for stainless steel bottles. Make sure to soak the inside of the lid as well to clean the bottle fully. After a couple of hours, rinse it well with water and allow it to dry. You may also leave it overnight for better results.

Bleach and Baking Soda

If the stain or grime in your bottle can’t be removed by vinegar or baking soda alone, combining the sanitizing and cleansing powers of bleach and baking soda may work. Combine a teaspoon of baking soda and a teaspoon of bleach inside the bottle. Pour some water up to the brim.

Using the same solution, clean the lid as well. Allow the mixture to soak your bottle overnight and rinse with warm water in the morning. Let the bottle and the lid dry naturally.
