What you need to know about de-icers and saltRock salt is beneficial in melting thick layers of ice and snow and one of the first things people reach for when there is bad weather coming. It breaks down the ice on roads and other paved surfaces quite well. It is a matter of safety as ice on steps and walkways is extremely dangerous and leads to numerous injuries every year. De-icers are available that use various chemical variations of salt to melt ice on patios, walkways, and driveways. But as with everything, there are pros and cons. Salt is very soluble and can run off into nearby bodies of water and have a tremendous effect on plants in the area. Here is some information to help you weigh the pros and cons on using salt as a de-icer:



  • Prevents buildup of ice and snow.
  • Great on steps, slopes, walkways and steep driveways as it provides great results and grip and traction.
  • Reduces injury from slipping, sliding and falling on ice.
  • Salting before and after a storm prevents ice and snow from forming a thick layer and makes it easier to clear snow off the treated surfaces.



  • It can significantly damage plants, grass and trees if it saturates the soil.
  • Salt contamination delays bud break, growth and can cause browning.
  • Can cause corrosive damage to concrete surfaces, motor vehicles and recreational vehicles.
  • Can damage wildlife and lead to food and shelter loss.
  • Can damage animals paws and harmful if too much is ingested through eating snow or drinking from puddles.
  • Can be harmful to children if swallowed but also if they get it in their eyes causing abrasions to the eye or harming their skin.

There are ways to prevent salt from harming areas of your property. They are:

  • Use de-icers with lower salt content or mixed with other materials such as ash or sand.
  • Place burlap, plastic or a snow fence over delicate perennials before snow and ice come.
  • Do not stack snow or shovel snow with salt onto plants or grass.
  • If contaminated, try applying a layer of gypsum to the soil to displace the sodium with calcium and improve the drainage of the soil.


Tips for using deicing products:

  • Purchase the correct blend according to your climatic conditions and average low temperatures so that you will need to use less salt.
  • Keep walkways cleared as the snow falls before it becomes ice.
  • Pre-treat before the storm so that you will use less de-icer.
