Introduction

When it comes to de-icing roads and sidewalks during the winter months, two popular options are Calcium Chloride and Magic Salt. Both products are effective at melting ice and snow, but they have different attributes that make them unique. In this article, we will compare the characteristics of Calcium Chloride and Magic Salt to help you decide which one is best for your needs.

Cost

One of the first factors to consider when choosing between Calcium Chloride and Magic Salt is the cost. Calcium Chloride is typically more expensive than Magic Salt, making it a less budget-friendly option for large-scale de-icing projects. Magic Salt, on the other hand, is more affordable and can be a cost-effective choice for those looking to save money without sacrificing performance.

Effectiveness

Both Calcium Chloride and Magic Salt are effective at melting ice and snow, but they work in slightly different ways. Calcium Chloride is a hygroscopic material, which means it absorbs moisture from the air and generates heat when it comes into contact with ice and snow. This makes it a fast-acting de-icer that can quickly melt even thick layers of ice. Magic Salt, on the other hand, is a blend of salt and a liquid de-icer, which helps it to work at lower temperatures than traditional rock salt.

Environmental Impact

Another important factor to consider when choosing between Calcium Chloride and Magic Salt is their environmental impact. Calcium Chloride is known to be harmful to plants and animals, as well as corrosive to metal surfaces. It can also leach into groundwater and contaminate water sources. Magic Salt, on the other hand, is considered to be more environmentally friendly, as it is made from natural ingredients and is less harmful to the environment.

Storage and Handling

When it comes to storage and handling, Calcium Chloride and Magic Salt have different requirements. Calcium Chloride is typically sold in pellet or flake form, which can be messy to handle and store. It also has a tendency to clump together, making it difficult to spread evenly. Magic Salt, on the other hand, is usually sold in granular form, which is easier to handle and spread. It also has a longer shelf life than Calcium Chloride, making it a more convenient option for long-term storage.

Residue

One of the drawbacks of using Calcium Chloride as a de-icer is the residue it leaves behind. Calcium Chloride can leave a white powdery residue on surfaces, which can be unsightly and difficult to clean up. Magic Salt, on the other hand, leaves little to no residue, making it a more aesthetically pleasing option for de-icing roads and sidewalks.

Conclusion

In conclusion, both Calcium Chloride and Magic Salt are effective de-icing agents that can help keep roads and sidewalks safe during the winter months. However, they have different attributes that make them suitable for different situations. If cost is a concern, Magic Salt may be the better option. If you are looking for a fast-acting de-icer, Calcium Chloride may be the way to go. Consider the environmental impact, storage and handling requirements, and residue left behind when choosing between Calcium Chloride and Magic Salt for your de-icing needs.
