How do you safely kill the algae growing in your drinking water container?

It is not recommended to use containers that have grown algae as a drinking water source, as the presence of algae can raise significant concerns about the quality and safety of the water.

Regardless, if you find yourself in such a situation, here are some steps you can take to safely kill algae in a drinking water container (though it's worth noting that it might be best to consider discarding the water and the container):

1. Thorough Cleaning: Begin by emptying the container and thoroughly cleaning it using dishwashing liquid and hot water. Remove any visible algae or slime on the container's surface, paying close attention to the corners, spout, and lid.

2. Soaking Solution: Prepare a soaking solution by mixing one part water with one part white vinegar. Submerge the cleaned container in this vinegar-water solution and make sure that the affected areas are fully covered. Leave it to soak for several hours or overnight.

3. Baking Soda Rinse: After soaking, rinse the container thoroughly with clean water to remove the vinegar solution. Create a baking soda mixture by combining equal amounts of baking soda and water to form a paste. Use this paste to scrub any remaining algae spots inside the container.

4. Sun Exposure: If possible, expose the clean container to direct sunlight. Sunlight can have natural sanitizing effects and can help eliminate any remaining algae or bacteria. Leave it in the sun for several hours to further reduce the risk of algae growth.

5. Disinfection: Use a food-grade sanitizer or a mild bleach solution to sanitize the container. Follow the instructions provided on the sanitizer package. Make sure to rinse the container thoroughly after disinfection to remove any residual chemicals.

6. Fill and Store Properly: Once the container is clean and sanitized, refill it with fresh drinking water. Store the filled container in a cool place and avoid direct sunlight. Regularly monitor the water for any signs of algae growth or other contamination.

Remember that DIY cleaning methods might not guarantee the complete removal of algae or other potential contaminants. If you have concerns about the quality or safety of your drinking water, it's best to consult with a water quality professional or contact your local health department for advice and recommendations on accessing safe drinking water.
