What is distilled water
Distilled water is water that has been subjected to an intensive purification process called distillation. This means heating the water and returning it to a liquid state. It’s the water without minerals, contaminants and other possible contaminants found in a typical tap water. Learn all the benefits of distilled water. Distilled water is commonly used in laboratories, aquariums, and certain medical applications due to its purity. However, as awareness grows about the environmental impact of water sourcing and purification processes, many are now exploring sustainable water options to minimize their ecological footprint. By choosing sourced or filtered alternatives, individuals can enjoy clean water while also contributing to better water resource management in their communities.
Even though it’s used for everything from water testing labs and cooling in cars to some cooking, distilled water is so pure it needs to be stored and treated differently from any other water in order to keep it pure and free of contamination.
Why Distilled Water Requires Special Care
Distilled water’s purity is both its strength and its weakness. It’s free from impurities that could affect certain processes, making it ideal for many specific uses. However, its lack of natural minerals and ions also means it can absorb substances from its surroundings more readily, making it prone to contamination if not stored and handled correctly.
For example, if distilled water is stored in a metal container, it could absorb metal ions, compromising its purity. Therefore, knowing how to correctly store and handle distilled water is crucial to preserve its integrity and ensure it remains safe for its intended use.
Does Distilled Water Go Bad?
Distilled water, when stored properly, doesn’t go bad or spoil in the traditional sense. Since it is purified through distillation, it contains no impurities or microorganisms that would typically cause it to deteriorate. However, over time, if not sealed properly, it can absorb dust, bacteria, or chemicals from the air, potentially affecting its quality. The key to maintaining the freshness of distilled water is to store it in a clean, airtight container, away from direct sunlight and heat sources.
How long can distilled water be stored? When kept in optimal conditions, distilled water can last indefinitely. It’s best to consume it within a reasonable timeframe, such as 1-2 years, to ensure its purity and taste are not compromised. If you notice any changes in the water’s appearance or odor, it could be a sign that it has been contaminated after opening. Storing distilled water in a cool, dry place and sealing it tightly will help maintain its quality for a long period.
What are the ideal containers for storing distilled water?
The choice of container is fundamental when storing distilled water. The container material should be non-reactive and should not leach substances into the water over time. Glass and certain types of plastic are typically recommended.
- Glass: It is an excellent material for storing distilled water as it does not react with the water or release any substances. Glass bottles or jars with airtight seals are often used.
- Plastic: Not all plastics are suitable for storing distilled water. Look for containers made of high-density polyethylene (HDPE) or polypropylene, as they are generally safe and do not leach harmful substances into the water.
How to Store Distilled Water
The best way to store distilled water is to keep it in a clean, airtight container, preferably made of glass or food-grade plastic. It’s important to store the water in a cool, dry place, away from direct sunlight and heat sources, as UV light and high temperatures can degrade the quality of the water over time. Keeping the water sealed prevents any contaminants from entering the container, maintaining its purity.
For long-term storage, it’s recommended to use containers with tight-fitting lids to avoid exposure to air, which could introduce bacteria or other impurities. Avoid using containers that have been previously used for other substances, as residue could affect the water. By following these storage practices, you can ensure that your distilled water remains safe and pure for use.
How to Store Distilled Water After Opening
Proper storage of distilled water is essential to maintain its purity and prevent contamination after opening. To store distilled water, always transfer it to a clean, airtight container if it wasn’t already sealed when purchased. This prevents dust, bacteria, and other particles from getting into the water. The container should be kept in a cool, dry place, away from direct sunlight and heat sources, as exposure to light and warmth can cause the water to degrade over time.

Glass or BPA-free plastic containers are the best options for storing distilled water safely and maintaining its cleanliness.
Proper Cleaning and Preparation of Storage Containers
Before filling them with distilled water or substitutions to distilled water, all storage containers should be thoroughly cleaned. Any residue or contaminants left in the container can contaminate the water, defeating the purpose of distillation.
Start by washing the containers with a mild, non-perfumed detergent, and rinse thoroughly with tap water. Then, rinse a few times with a small amount of distilled water to remove any potential tap water contaminants. Allow the container to air dry completely before filling it with distilled water to prevent any bacterial growth.
The Right Environment for Storing Distilled Water
Once your distilled water is safely in its appropriate container, the next step is to consider where to store it. The storage environment can significantly affect the quality of the water over time.
The distilled water should be stored in a cool, dry place away from direct sunlight. Ultraviolet (UV) rays from sunlight can break down plastic containers over time, potentially leading to the leaching of harmful substances into the water. In addition, distilled water should be kept away from chemicals, strong odors, and heat sources to prevent contamination and degradation of the container.
Long-Term Storage: Do's and Don'ts
If you plan to store distilled water for a long period, there are a few extra precautions to take.
- Do seal the water container tightly. This keeps out air, dust, and other potential contaminants.
- Don’t open the container until you’re ready to use the water. Once opened, use the water quickly or move it to a smaller container to reduce the exposed surface area.
- Do check the water regularly for any changes in smell, taste, or appearance. These could indicate contamination.
