Quick Answer
Mix equal parts of water and white vinegar in the stainless steel bottle, let it sit for 10-15 minutes, then scrub with a soft-bristled brush and rinse thoroughly.
Removing Odors with Vinegar
To eliminate bad odors from a stainless steel bottle, mix equal parts of water and white vinegar inside the bottle. The recommended ratio is 50/50, but you can adjust it according to the severity of the odor. Let the mixture sit for 10-15 minutes, allowing the acid in the vinegar to break down and neutralize any lingering bacteria or residue.
Scrubbing and Rinsing
After the vinegar solution has sat for the recommended time, use a soft-bristled brush to gently scrub the interior of the bottle. This will help dislodge any remaining bacteria or residue. Be careful not to scratch the stainless steel surface, as this can lead to further contamination. Rinse the bottle thoroughly with clean water to remove any remaining vinegar solution and bacteria. Repeat the process if the odor persists.
Disinfecting with Baking Soda
For an added layer of protection against future odors, mix 1-2 tablespoons of baking soda with water to create a paste. Apply the paste to the interior of the bottle and let it sit for 30 minutes to an hour. Then, rinse the bottle with clean water and dry it with a soft cloth. This will help absorb any remaining moisture and prevent bacterial growth.
