Storing Distilled Water After Opening
Distilled water, when stored properly, can maintain its purity and stay free from contaminants for an extended period. Here’s a step-by-step guide on how to properly store distilled water after opening to ensure its quality remains intact.
Step 1: Use a Clean Container
Transfer the distilled water into a clean, airtight container made from materials that won’t leach chemicals into the water. Glass or food-grade plastic containers are the best choices. Ensure the container is sterilized or thoroughly cleaned before use to avoid any contamination.
Step 2: Seal Tightly
Once the distilled water is transferred, make sure to seal the container tightly. A good seal helps prevent air, which may contain contaminants, from getting into the water.
Step 3: Store in a Cool, Dark Place
Store the sealed container of distilled water in a cool, dark place away from direct sunlight. Sunlight can encourage algae or bacterial growth, even in distilled water if organic contaminants are introduced. A pantry or a cupboard away from any heat sources is ideal.
Step 4: Avoid Contamination
Every time you access the distilled water, be sure to use clean utensils or dispensers. Your hands, cups, or any object coming into contact with the water should be clean to maintain the purity of the water.
Step 5: Do Not Store for Prolonged Periods
Even with proper storage, try to use the opened distilled water within a few weeks to a couple of months. Over time, certain plastic containers may leach chemicals slowly into the water, and even small amounts of contaminants can proliferate if conditions become conducive.
Step 6: Monitor the Water Quality
If the distilled water starts to appear cloudy, has an odor, or you notice any other change in quality, it’s best to dispose of the water as it may be contaminated.
Special Considerations
If the distilled water is being used for sensitive applications such as laboratory work, medical devices, or certain industrial processes, it may be necessary to take additional precautions as recommended by relevant guidelines or manufacturer’s instructions.
Conclusion
With proper storage practices, you can extend the life of distilled water after it’s been opened. It is important to ensure that it is kept in a suitable container, sealed well, protected from contaminants, and used within a reasonable time frame to maintain its purity.
