Frequently Asked Questions
Have some questions or considerations? Here are the answers to some FAQs.
What temperature does ice melt?
Using rock salt and ice melt on concrete is a standard method of melting snow. However, different ice melt formulas are effective at different temperatures.It is important to know the temperature an ice melt product will be effective before you purchase it.
Firstly, the temperature of ice increases along with the ambient temperature of its surroundings. However, once this ice gets to its melting point, the gradual temperature increase ends. The ice transforms into water, and the temperature remains largely constant until all the ice melts. This ice water will stay at 32 F until it is all water. In other words, ice melts at 32 F.
Is ice melt bad for concrete surfaces?
According to the American Concrete Institute, many chemical compounds in today’s ice melt formulas are bad for concrete and ought to be avoided. They are:
- Ammonium Sulfate
- Aluminum Chloride
- Ammonium Nitrate
- Calcium Sulfate
- Magnesium Chloride
- Magnesium Sulfate
- Sodium Cyanide
Although some of the chemicals in ice melt can damage your concrete, the amount of water your concrete absorbs is the bigger culprit.
As water seeps into the concrete and freezes, it expands and can cause the surface to crack when it thaws.
When you use a de-icer on your concrete floor, it accelerates the process. It it continues, the water will eventually expose the coarse aggregate and compromise the concrete’s structural integrity.
A best practice is to clean up the slush left over by the de-icer quickly. This will limit the amount of water seeping into the concrete.
You also need to understand how each ice melt product will affect your concrete. For example, an ice melt product consisting mainly of Sodium Chloride will damage your concrete rebar, including nearby vegetation, groundwater, and soil structure.
On the other hand, Calcium Chloride ice melts tend to leave behind oily residue, which can discolor your concrete pavement. While Magnesium Chloride may be safe for pets, it can affect the structural integrity of the concrete. It must be used as a blended formula to reduce the damage to your concrete pavement.
Ammonium Sulfate and Ammonium nitrate are harmful to your concrete pavement. These chemical compounds must only be used as an ice melt of last resort.
Is ice melt the same as rock salt?
Ice melt is not the same as rock salt. While both products are great for keeping walkways free from slippery ice, they are as different as night and day.
Rock Salt
Rock salt is not so different from the salt you use to spice your food, and it is sodium chloride in its unprocessed form. If you mix salt with water, it turns to brine. Salt can melt ice because brine freezes lower than regular water. When you apply it to frozen concrete, the ice begins to melt. Rock salt may be different from ice melt; however, it has benefits and drawbacks.
Benefits
- Provides traction
- More affordable
- Can melt ice in temperatures as low as 5 F.
Drawbacks
- Not effective in negative temperatures
- Can corrode metal and damaged concrete
- Hurts pets’ Paws
- Can destroy plants
Ice Melt
This formula combines many chemical compounds and is far more effective than rock salt. Depending on the blend, ice melt can work at -25 F. The mixture comes in liquid or pellet form but doesn’t have the traction of rock salt. That said, ice melt has its benefits and drawbacks.
Benefits
- It is effective in frigid temperatures
- Melts ice quicker than rock salt.
Drawbacks
- More expensive than rock salt
- Can corrode metal and damaged concrete
- It is harmful to pets
- Can damage flora and fauna
- No traction
Application
Rock salt and ice melt are easy to apply on frozen surfaces. However, you must put on protective equipment, including hand and eye protection, before using these products. The best way to get the most is to apply either product before the snowfall arrives. Applying before the snow begins to fall ensures less ice build-up and accumulation after the snow stops.
Effectiveness
This isn’t a contest because ice melt is far more effective than rock salt. Ice melt also works faster and for longer.
Price
The price of rock salt and ice melt are within the same range, and you can buy both for less than $40 per 50lb bag at many physical and online stores. Rock salt will set you back $10 to $25 for a 50lb bag, while ice melt is slightly more costly at $20 to $40 per 50lb bag.
Rock salt seems to be the cheaper option. Still, you might need to use more of the product to get a result, making the ice melt the more economical choice if you’re going to do a lot of de-icing over the winter.
Safety
Ice melt and Rock Salt require handling care and can hurt your pet’s paws. Both products can damage vegetation so clear up as much of the product once the ice thaws.
How to melt ice without salt?
The best ice melt for concrete or asphalt that you can make without salt is by mixing a half-gallon of hot water with six drops of dishwashing liquid and 1/4 cup of rubbing alcohol. If you pour this homemade formula on your concrete, the frost and ice will bubble up and melt away. Remember to have a shovel at hand to clear up the slush left behind.
Can you use water softening salt or Epsom salt to melt ice?
Water softening salt or Epsom salt is also known as magnesium sulfate. It is an effective method for melting ice, just like regular table salt. It lowers the ice freezing point, consequently melting the ice or frost. The main benefit is that Epsom salt is eco-friendly and great for flora and fauna.
Why is Potassium Chloride ice melt dangerous?
While potassium chloride is generally considered to be less harmful to the environment and less corrosive to concrete than traditional salt-based ice melt products, it can still be dangerous in certain situations. Here are some reasons why:
- Risk of ingestion: Potassium chloride is a common ingredient in fertilizer and is often used in agriculture. If it’s ingested in large amounts, it can be toxic and lead to serious health issues.
- Slippery residue: When potassium chloride is used as an ice melt, it can leave a slippery residue on surfaces. This can increase the risk of slips and falls, especially on stairs or steep inclines.
- Limited effectiveness in extreme temperatures: Potassium chloride is less effective than traditional salt-based ice melt products in extreme cold temperatures. This means that it may not be effective in preventing ice buildup on surfaces during very cold weather, which can create additional hazards.
- Harmful to some plants: While potassium chloride is generally considered to be less harmful to plants than traditional salt-based ice melt products, it can still be harmful to some types of plants. Overuse or exposure to potassium chloride can lead to root damage and stunted growth in some plants.
- Corrosive to some metals: Potassium chloride can be corrosive to some types of metals, including aluminum and brass. If used on surfaces containing these metals, it can cause damage and reduce the lifespan of the surface.
