Saltnets FAQs

  1. Will Saltnets® work on my roof? Yes, Saltnets® will work on any surface that you wish to melt/prevent ice and snow. Many customers prefer Saltnets® for their roofs because they can be quickly placed and removed they also limit the amount of salt runoff - which reduces the risk of corrosive damage. Please use caution around materials that are susceptible to corrosion.         
  2. Can I use Saltnets® in the rain? No, DO NOT USE IN THE RAIN. Salt based products will dissolve in rain, they are intended to use in temperatures below freezing.
  3. Why does my mat have ice/snow on top of it? Saltnets® mats, like other melting agents, are designed to prevent ice/snow from forming a bond to the ground's surface. The melting agents inside your mat slowly dissolve and produce a brine that gradually flows out of the mat, therefore preventing a bond from forming. In extreme cold conditions with heavy snowfall, snow may build up on top of the mat. As time passes, the mat will eventually melt this buildup, but if you wish to conserve the lifespan of your mat, we recommend sweeping or shaking off excessive amounts of snow.
  4. I just put my Saltnets® mat out, why does it look like nothing is happening?
    The melting agents inside of your Saltnets® mat pull moisture from the surrounding environment, which causes a reaction that produces heat and dissolves moisture into a brine. It may take some time for the mat to become active at first, especially in very dry climates.
  5. How long does it take to melt snow/ice?
    The melting rate for snow and ice will vary greatly depending on your local weather conditions. For example, at 18º Fahrenheit, an active mat should melt about 1/2" of snow every 3-4 hours.
  6. After I opened my Saltnets® package, the mat felt wet. Is this normal?
    Yes, the melting agents inside the mat pull moisture from the surrounding environment (this is why your package was vacuum-sealed). Moisture activates the mat and starts the melting process.
  7. How should I properly store my mat when it’s not being used?
    To prolong the lifespan of your mat, we highly recommend keeping it sealed in its original packaging until you're ready to use it. If you have already opened/used your mat and would like to store it, it's extra important that you take the necessary precautions to properly store it. Mats that are not in use need to be stored in an air-tight, vacuum-sealed bag or container. DO NOT store your mat inside your house without properly sealing it off from moisture first. This is extremely important because failure to do so will damage your mat and cause a mess.
  8. How long will my mat last?
    A Saltnets® mat's longevity is weather dependent. Each mat has about 5 pounds of melting agents, which will melt 13" of snow/ice at 15º Fahrenheit. Each mat was designed to last one average winter season; however, it may last longer or shorter depending on your local weather conditions. To maximize your mat's lifespan, remove large amounts of snowfall by dusting it off or shaking it.
  9. Do the mats have toxic chemicals in them?
    No, each mat contains a blend of common salts including calcium chloride, sodium chloride, and magnesium chloride. These are all non-toxic, commonly used melting agents.
  10. How do the mats work?
    A Saltnets® mat works by drawing in moisture and reacting with its melting agents to provide heat. Once the mat heats up, it will melt snow and ice, creating a brine that is then wicked around the mat. The mat then dries up and gets ready for its next round of winter precipitation. There are two ways you can use a Saltnets® mat: you can either lay it down before winter precipitation occurs or you can wait and place it on top of previously fallen snow or ice. If you lay it down before precipitation, it can be used to prevent snow and ice from ever bonding to the ground’s surface.
  11. Why can't it melt faster?
    We have designed the mats with a balance between effectiveness and conservation. We could create a mat that burns through ice and snow immediately; however, you would not be able to touch the mat and it would wreak havoc on the environment. Our mats are safe and will prevent snow and ice from bonding to the surface as well as provide improved traction when placed on top of ice and snow.
  12. How does a Saltnets® mat help prevent injury to my pets' paws?
    When a pet walks on exposed melting agents such as salt rock, they risk a high chance of getting rock crystals stuck in their paws. If this happens, your pet will most likely lick its paws in an attempt to remove the crystals. Ingesting salt rock is not recommended for anyone and it can be especially harmful to pets. A Saltnets® mat features tube-like construction which houses our blend of melting agents, so there's no way salt could get stuck in your pets' paws.
  13. I would like to purchase the rubber base mat, but I don't see it on your order page. Where can I find one?
    We have currently sold out of the rubber base mats and have more on order. Saltnets® entrance-style mats are designed to fit into common base mat systems —which you can find at many retailers.
  14. I live in Georgia, will Saltnets® mats work in the freezing rain?
    Yes, Saltnets® mats will melt ice caused by freezing rain, as well as keep ice from forming a bond to your walkway surfaces.
  15. Can I purchase Saltnets® mats in local stores?
    Saltnets® mats are currently for sale online at and We would love to be in your local stores, please ask them to stock Saltnets® mats for you.
