Quick Answer
Clean containers with mild soap and water, allow to air dry, and then sanitize with a 1:10 bleach-to-water solution for at least 10 minutes before storing long-term water.
Pre-Cleaning Preparation
Before cleaning containers for long-term water storage, remove any labels and residue using a gentle adhesive remover or a mixture of equal parts water and white vinegar. Rinse the container thoroughly with warm water to remove any remaining residue.
Cleaning Process
Mix 1-2 tablespoons of mild soap (preferably fragrance-free) with 1 gallon of warm water. Use a soft-bristled brush to scrub the container, paying particular attention to any areas with visible residue or stains. Rinse the container thoroughly with clean water, making sure to remove any soap residue.
Sanitizing and Drying
To sanitize the container, mix 1 tablespoon of unscented bleach with 1 gallon of water. Submerge the container in the bleach solution and let it sit for at least 10 minutes. Remove the container from the solution, rinse it with clean water, and allow it to air dry. This will help prevent the growth of bacteria, mold, and mildew, ensuring the stored water remains safe and potable.
