Yes, rock salt **needs to be covered** when in storage, particularly to protect it from moisture.
## Why Covering Rock Salt is Essential
Based on recommendations, storing rock salt properly, which includes covering it, is crucial to maintain its quality and effectiveness. Exposure to moisture, such as rain or snow, can significantly damage the salt.
Here's why covering is necessary:
* **Prevents Clumping:** When moisture comes into contact with salt, it causes the granules to stick together, forming large clumps. This makes the salt difficult to scoop, spread, and use efficiently.
* **Avoids Hard Crust Formation:** Prolonged exposure to moisture can create a hard, solid crust on the outer layer of the salt pile or container, rendering the salt underneath less accessible or requiring extra effort to break apart.
* **Maintains Effectiveness:** Dry, loose salt spreads more evenly and dissolves properly to melt ice and snow. Moisture damage compromises these properties, reducing the salt's effectiveness as a deicer.
## How to Properly Store Rock Salt
To prevent moisture damage and ensure your rock salt is ready for use when winter weather hits, proper storage is key.
* **Use an Airtight Container:** As recommended, keeping your winter salt in an **airtight container** is the most effective way to protect it from humidity and direct moisture. This prevents both external moisture and airborne humidity from affecting the salt.
* **Protect from Rain and Snow:** Salt should **never be exposed to rain or snow** while in storage. Whether you're storing it outdoors or in a shed, ensure the covering or container is waterproof and completely shields the salt from precipitation.
* **Choose a Dry Location:** Store containers or covered piles in a dry area away from sources of moisture, if possible.
By taking these steps, you ensure your rock salt remains loose, easy to use, and effective throughout the winter season.
