Snow and Ice Management Terminology

De-Icing: Deicing is the reactive application of ice control products to driving or walking surfaces, to melt existing snow and ice. Deicing is performed after snow removal operations to melt any remaining snow and ice.

Anti-Icing: Anti-icing is the pro-active application of ice and snow melting products to driving or walking surfaces prior to a snow or ice storm. Anti-icing helps prevent snow and ice from bonding to the pavement, allowing snow and ice to be cleared more easily. When used effectively, anti-icing can create some of the safest conditions in the winter, and be a cost-effective alternative to de-icing.

Understanding the difference between anti-icing and de-icing can yield insight into the different approaches utilized by professional snow removal services. Professional services do not always rely on one approach or tool for all storms, but use a variety of tools to maintain the safest conditions possible during the season. A main goal for a professional service provider, which benefits both the property manager and the contractor, is to reach a designated level of service as quickly and efficiently as possible. Any information in this section is very general, only a trained and qualified snow and ice professional should make decisions regarding what material to use on a specific location. Currently the most common products used are:

Salt: Sodium Chloride, or rock salt, is the most common de-icer in use today. Generally this product is effective, though not in all conditions. Only a knowledgeable snow and ice contractor will know when and how to apply the right amount of material to create a safe environment for your property. In very cold conditions (typically less than 23 degrees F), salt begins to lose its effectiveness and is either not used or is overused in an attempt to make up for reduced performance.


There are many other products in use in today, these products include:

• Potassium Chloride 
• Magnesium Chloride
• Calcium Chloride
