The above ingredients are sometimes sold straight or are often blended. Cheaper blends will have a higher salt (sodium chloride) content. Some blends use a treated salt or “accelerator” which is often composed of magnesium chloride. These accelerants are typically coatings for the salt crystal which may slightly improve the ice melting performance. Be cautious of product claims where the price is somewhat comparable to rock salt yet it’s performance is “fantastic”. It is more likely salt in disguise. There are no magic ingredients in the ice melt world, just different combinations of the above components.
Purchasing Considerations:
- How much needs to be spread for each application?
|
|
| |
- Does it work at low temperatures?
|

|
| |
- Does handling it effect your skin?
|
- How harmful is it to vegetation?
|
|
- How well does it go through your spreader?

What To Use?
Large areas such as parking lots typically require salting, other areas such as walks or entryways, consider your priorities. Most common considerations are, price per application, effectiveness, potential cement or plant damage, tracking, and ease of spreading.
The lowest cost per pound is rock salt. The next lowest cost are treated salt and a high salt content blends. Again, be cautious of the additional benefits gained with the use of a low to medium priced blend which includes very small percentages of calcium or potassium as a blended additive.
Our Evco Premium Ice Melter is a blend with a good amount of calcium, some potassium, a little magnesium and some salt. It is a great mix for a mid to mid-high priced product. This type of blend spreads nice, and offers a good balance of desirable characteristics.
Arguably the best product is calcium chloride pellets. It melts fast, it tracks very little and is friendly to plants. It also takes very little to be effective, so its price per square foot is actually very reasonable. Also it is lighter than salt so you get more per bag. The only notable drawback is it may dry your skin out if you come in contact with it. Use a scoop or spreader, and gloves (not leather) to be safe.
One Last Tip
The key to controlling cost and minimizing the negative effects of using ice melt products is using the right amount of product. The tendency is to use too much each time.
