Factors Affecting De-Icer Efficiency

Let's delve into some of the factors that impact the efficiency of de-icers.

1. Temperature

Let's first examine de-icer effectiveness by looking at the range of temperatures in which it can provide de-icing action. The “practical” lowest temperature limits for these materials mean that the product is effective within 15-20 minutes of being applied.

Here's additional information on the effectiveness temperatures of different types of de-icing materials (ranked):

In terms of temperature adaptability, calcium chloride and magnesium chloride are the most effective, particularly for lower temperature ranges where other de-icers' efficiency diminishes.

2. Penetration Rates  

Let's look at different penetration rates for some of the types of de-icers:

• Calcium chloride de-icers penetrate ice at all temperatures at a rate that's twice as fast as other de-icers.
• Sodium chloride de-icers penetrate ice at lower rates than calcium chloride. However, they do perform similarly to calcium chloride over 45-60 minutes at milder temperatures of 15-25º Fahrenheit. But they are substantially inferior compared to calcium chloride at 5º Fahrenheit or lower.
• Urea and potassium chloride are significantly less active than calcium chloride and sodium chlorides, and they become nonpenetrating at 15º Fahrenheit and lower.

3. Ice Melt Process

What melts ice the fastest? This is a common question that's considered when choosing a product for de-icing. The most effective de-icers take action quickly, helping to penetrate the snow or ice by undercutting the material.

There are differences in how fast these compounds turn into a de-icing brine at low temperatures. Both calcium chloride and magnesium chloride are liquid in their natural states. In addition, when the solid forms of these compounds come into contact with water they work swiftly and naturally release heat.

As soon as calcium chloride and magnesium chloride come into contact with the snow, they pick up water and form a strong brine. By emitting heat, they are able to provide additional ice-melting effects, creating more water, which in turn creates more brine. This process repeats until the material is gone.

4. Other Factors to Consider 

Other factors include:

• How much material is needed.
  
• How long will each de-icer work.
  
• The shape of the de-icer.
  

Look at the volume of ice each can melt pound-for-pound within normal temperature conditions over a reasonable amount of time. When you are reviewing the materials based on volume, most users will first choose calcium chloride followed by magnesium chloride, then sodium chloride. 

In addition, you can consider how long each de-icer will provide ice melting action. The longer the action, the fewer applications you'll need. Natural state liquid de-icers such as calcium chloride and magnesium chloride will continue to work the longest. Finally, look at the shape of the granules. Round particles have a smaller surface which means they're more effective at boring down vertically instead of horizontally. 

To Sum Up: What Melts Ice the Fastest?

In conclusion, salt melts ice the fastest. You can use some combination of sodium chloride, with calcium chloride and/or magnesium chloride. This combination will work more effectively than plain rock salt alone. 

People buy various types of salts to melt ice. Even though rock salt is cheaper to buy, it can be more corrosive to concrete in addition to vehicles. Ice melt blends will melt the ice faster, and it's less corrosive to cars and asphalt. If you are still confused about how ice melt is different from rock salt we have an article on Rock Salt vs Ice Melt that covers this topic in great detail.

Environmental Impacts of De-Icers

There has been an increasing emphasis on the environmental impact of de-icers. Nearly all studies have concluded that factoring in the alternative of hazardous solutions, the benefits that come from de-icers outweigh the negatives. Despite this, it's important to address these concerns. 

The residue is one thing to consider. What is the material of the surface you are applying to and if there is foot traffic into a building, what is the material of the flooring in the building. These are factors to consider when deciding what type of ice melt to use. For example, products with calcium chloride tend to have a lesser impact on concrete. Additionally, the impact on vegetation is another consideration. All de-icing materials can potentially damage plants, however, magnesium chloride is the safest option for vegetation. 

Alternative de-icing agents are also being researched and tested. Potassium acetate is a promising option due to its effectiveness at lower temperatures and a smaller environmental footprint compared to traditional salts.
