How to Get the Bad Smell Out of Nalgene Water Bottles

Nalgene makes plastic, reusable bottles in several colors. Like many plastic bottles, these may develop an odor. Musty smells or smells from liquids, such as milk, left too long in the bottles can linger if you don't wash the bottles well. Often, simply washing the bottles with dish soap is not enough to remove a bad, lingering odor. You can get the bad smell out of your Nalgene water bottle through an additional step, after cleaning, however.

Step 1

Fill the nalgene bottle with warm water. Add a tsp of dish detergent and close the lid. Shake the bottle to mix the detergent with the water.

Step 2

Open the lid. Use a clean bottle brush to brush clean the inside of the bottle.

Step 3

Pour out the soapy water. Rinse the bottle with warm, clean water.

Step 4

Place 2 heaping tsp. of baking soda in the bottle. Fill the bottle completely and replace the lid. Allow the baking soda and water to sit in the bottle for 30 minutes.

Step 5

Pour out the baking soda and water. Rinse the bottle well, then dry with a clean towel. Clean the lid with a wet, soapy cloth. Place the bottle (with the lid open) in the dish drainer to complete drying.
