Is it Safe to Use a Barrel for Drinking Water After Cleaning with Dish Detergent and Hot Water?

Water storage is a critical aspect of emergency preparedness and survival planning. Barrels are often used for this purpose due to their large capacity and durability. However, the safety of the stored water can be compromised if the barrel was previously used to store harmful substances. A common question that arises is whether a barrel that was previously filled with sodium hypochlorite and sodium hydroxide can be safely used for drinking water storage after cleaning it with dish detergent and hot water. This article aims to provide a comprehensive answer to this question.

Understanding Sodium Hypochlorite and Sodium Hydroxide

Sodium hypochlorite is a compound often used as a disinfectant or a bleaching agent. Sodium hydroxide, on the other hand, is a strong base used in many industries, including paper manufacturing, textile production, and soap making. Both these substances are corrosive and can cause harm if ingested or come into contact with the skin or eyes.

The Cleaning Process

Cleaning a barrel that contained these substances involves thoroughly rinsing it with water, followed by scrubbing with dish detergent and hot water. The detergent helps to break down and remove any residual chemicals. After scrubbing, the barrel should be rinsed again with hot water to remove any soap residue.

Is it Safe?

While cleaning with dish detergent and hot water can remove a significant amount of the residual chemicals, it may not be sufficient to ensure the safety of the water stored in the barrel. Sodium hypochlorite and sodium hydroxide are both highly soluble in water, meaning they can penetrate the surface of the barrel, making them difficult to completely remove.

Recommendations

Given the potential risks, it is generally not recommended to use a barrel that was previously filled with sodium hypochlorite or sodium hydroxide for drinking water storage, even after thorough cleaning. Instead, consider using barrels that were specifically designed for water storage. These barrels are made from food-grade materials and are safe for storing drinking water.

Conclusion

While it is possible to clean a barrel that was previously filled with harmful substances, the safety of the water stored in such a barrel cannot be guaranteed. Therefore, for the sake of your health and safety, it is best to use barrels that were specifically designed for water storage.
