Cleaning instruction for my EVMAN Aluminum Bottle
For thorough cleaning, soap and warm water or even an occasional vinegar and water solution work well.
Using Dish soap : Empty the water bottle and fill it with dish soap and hot water. If there are really tough stains and/or mold, you can use a long brush to scrub the hard to reach areas of the bottle. Or, you can mix a cup of uncooked rice in with the dish soap and water and shake the bottle vigorously.Rinse your bottle with fresh water. Let air dry.
Deep clean with vinegar and baking soda : Pour 2 tbsp. of baking soda into the bottle, then add 1/2 cup of vinegar. this is going to create some major fizzing which will likely fill the bottle. Allow this to sit for about five minutes. (Vinegar kills mold and mildew germs and baking soda will aid in cleaning and removing odors.) Use bottle brushes or soft bristle toothbrushes to scrub the bottle. Thoroughly rinse your bottle with fresh water and let air dry.
Alternative : Put about a cup of uncooked rice into the bottle followed by 2 tbsp. baking soda, and 1/2 cup vinegar. Let it fizz up like mentioned before, close the lid, and shake with all your might. Thoroughly rinse your bottle with fresh water and let air dry.
