De-icing salt, especially after opening, should be stored in a dark, dry environment in fully sealed, air-tight, and water-resistant packaging. This prevents moisture absorption, which can render the salt less effective.
Why Proper Storage Matters
De-icing salt, also known as ice melt, is hygroscopic, meaning it readily absorbs moisture from the air. When this happens:
- Reduced Effectiveness: The salt clumps together and may not spread evenly, reducing its ability to melt ice.
- Wasted Product: Moisture can dissolve the salt prematurely, causing it to become a slushy mess, making it unusable.
- Damage to Storage Area: Leaking, damp salt can damage storage areas like garages or sheds.
Ideal Storage Conditions
To maintain the effectiveness of your de-icing salt, aim for these conditions:
- Airtight and Water-Resistant Packaging: Use heavy-duty plastic bags, buckets with tight-fitting lids, or other containers that prevent air and moisture from entering. Re-seal opened bags carefully.
- Dark Environment: Store the salt away from direct sunlight, as UV rays can degrade some chemical components in certain types of ice melt.
- Dry Location: Choose a storage area that is not prone to dampness or flooding. Basements can be problematic unless properly dehumidified. Garages, sheds, or indoor storage closets are often suitable.
- Cool Temperature: While not as critical as dryness, extreme heat or cold can affect the salt's performance over very long periods. A stable, moderate temperature is ideal.
Practical Storage Solutions
Here are some practical ways to store de-icing salt:
- Original Packaging (Enhanced): If you have the original bag, seal it tightly with duct tape or heavy-duty packing tape after each use. Place the sealed bag inside a larger, airtight plastic container.
- Plastic Buckets: Transfer the salt to a durable plastic bucket with a secure lid. These are readily available at hardware stores.
- Storage Bins: Large, airtight storage bins designed for outdoor equipment can also be used to protect the salt from the elements.
- Elevated Storage: Store the salt off the ground on a pallet or shelf to prevent moisture from seeping in from the floor.
By following these storage guidelines, you can ensure that your de-icing salt remains effective throughout the winter season and beyond.
