Choosing the Right Ice Melt for the Job

Not all winter conditions call for the same deicer. Temperature, surface type, traffic levels, and concerns about corrosion or vegetation can all influence which product performs best.

Understanding each option's strengths and limitations helps you choose the right product for every commercial and residential account.
 

How Deicers Work

Ice melts lower the freezing point of water by creating a brine on the ice surface. Once that brine forms, it begins breaking the bond between ice and pavement, making snow and ice easier to remove.

The effectiveness of that process depends largely on temperature and the product's active ingredients.
 

Rock Salt (Sodium Chloride)

Best suited for: General snow and ice control on parking lots, sidewalks, and other large areas.

Effective down to: Approximately 15°F

Rock salt remains the most widely used deicer because it delivers dependable results at a competitive price. Contractors managing high-volume winter maintenance programs often rely on it as their primary material.

Performance declines as temperatures fall, and repeated applications can damage concrete, metal surfaces, and surrounding vegetation.
 

Magnesium Chloride

Best suited for: Contractors seeking better cold-weather performance than traditional rock salt.

Effective down to: Approximately -10°F

Magnesium chloride balances performance and versatility. It stays effective at lower temperatures than sodium chloride and is often chosen when contractors want better cold-weather performance without moving to premium-priced products.

Like other chloride-based products, it can still affect concrete, metal, and plant material if overapplied.
 

Potassium Chloride

Best suited for: Moderate winter conditions and sites that prefer potassium-based products.

Effective down to: Approximately 20°F

Potassium chloride offers an alternative to sodium-based products and performs well during milder winter weather. Contractors should keep in mind that melting performance slows as temperatures approach the lower end of its operating range.

Overuse may still affect nearby turf and ornamental plants.
 

Blended Ice Melts

Best suited for: Balancing performance, cost, and flexibility across a variety of properties.

Effective down to: Depends on the blend.

Most blended deicers combine multiple ingredients to improve melting speed and temperature performance while managing costs. Because formulations vary significantly by manufacturer, review the product label when selecting a blend for a specific application.
 

Which Ice Melt is Right for Your Customers?

The best choice depends on the weather conditions you're facing and the property owner's expectations.

Managing large commercial sites? Rock salt and blended products often provide the best value.

Looking for a balance of performance and cost? Magnesium chloride may be a good fit.

Working in milder conditions? Potassium chloride can be an effective option.
