Best Practices for Storing Distilled Water After Opening

Distilled water is a type of purified water that has gone through a distillation process to remove impurities and minerals. This makes it ideal for various purposes such as drinking, cooking, cleaning, and medical procedures. However, once you open the container of distilled water, it can easily become contaminated if not stored properly. In this blog post, we will discuss how to store distilled water after opening to ensure its purity and safety.

Why is proper storage important?

When you open the container of distilled water, it becomes vulnerable to contamination from various sources such as air-borne bacteria or dust particles in the environment. Additionally, if not stored correctly at room temperature or higher than 70°F (21°C), microorganisms may grow rapidly in the water leading to bacterial growth that could be harmful when consumed.

Air-tight Containers

One way of keeping your distilled water safe from contamination after opening is by storing it in an air-tight container. Air-tight containers prevent any external elements like dirt or bacteria from entering the bottle which keeps your distilled water clean and pure.

Dark Glass Bottles

Another way of ensuring that your distilled water stays uncontaminated is by using dark glass bottles instead of clear plastic bottles. This helps prevent exposure to sunlight which can promote algae growth thereby contaminating your purified drinking supply..

Cool Dry Place

Lastly but very importantly; Ensure you keep your opened bottled distilled-water in a cool dry place away from direct sunlight exposure since this usually speeds up microbial growth greatly while also promoting changes within molecular structure present within H²O.

In summary:
To ensure long-lasting freshness with no risk factors involved always store bottled-distilled-water properly.
Use air-tight opaque containers
Store them far away from direct sun rays
Keep them cool and dry
With these few tips, your distilled-water remains pure and safe for consumption no matter how long you store them after opening.


Storing distilled water properly is essential to preserving its purity and safety. By using air-tight containers, dark glass bottles, and storing it in a cool dry place you can ensure that your purified drinking supply will remain fresh for longer periods without risk of contamination thus maintaining the mineral properties within H²O. Follow these simple guidelines to make sure you keep enjoying the benefits of distilled water!
