Ice Melt and Winter Salt Guide for Businesses: Rock Salt vs Calcium Chloride
October 24, 2026 · RPS Distributors
When ice forms on parking lots, walkways and loading docks, businesses need to act fast. Choosing the right ice melt saves money, works better in the cold and protects surfaces.
The most common ice melt types
| Product | Works best down to (approx.) | Pros | Cons |
|---|---|---|---|
| Rock salt (sodium chloride) | About 15°F | Lowest cost, widely available | Slows in deep cold; can harm plants and concrete |
| Calcium chloride | Well below 0°F | Works fast in deep cold | Higher cost; can leave residue |
| Magnesium chloride | Below 0°F | Gentler on surfaces and plants than rock salt | Higher cost |
| Blends | Varies | Balance of cost and performance | Check the label |
Temperatures are approximate and vary by product. Check the label for the rated working temperature.
Tips for using ice melt
- Apply before the storm when possible. A light layer before snow or freezing rain stops ice from bonding to the surface.
- Shovel first, then treat. Ice melt works better on a thin layer than under deep snow.
- Use the right amount. Too much wastes product and can damage concrete and landscaping.
- Sweep up leftover product after the storm to reduce tracking indoors.
Protecting concrete and floors
New concrete (less than a year old) can be damaged by some ice melts. Use a product labeled safe for concrete, and place mats at entrances to catch salt before it is tracked inside.
Plan your supply
Order ice melt early in the season. When a big storm is forecast, demand spikes and supply can run short. Keep shovels, scrapers and gloves on hand too.
