To keep your container clean and reusable, we recommend the following:
Use on tablespoon baking soda per half-gallon of regular water. Swish this solution around the bottle and then pour it out. Rinse well, and seal the container until ready to refill.
Use one teaspoonful of household bleach or hydrogen peroxide (the over-the-counter type works fine) per gallon of water. Swish the solution around so it contact all surfaces, then fill the container with tap water. Let the solution stand for about 5-15 minutes, then empty and rinse your container repeatedly with tap water until the chlorine odor is gone. Let air dry, then seal.
