Magnesium Chloride vs Calcium Magnesium Acetate

Two very popular high-performance ice melting products are Magnesium Chloride and Calcium Magnesium Acetate (CMA).  They share a lot of the same strengths and they can be found for approximately the same price.

Which one is better? The answer depends on what you are trying to achieve.  Both are environmentally friendly, but one is gentler and the other melts at lower temperatures.  Let’s start off with a brief list of what the two ice melts have in common.

What do Magnesium Chloride and Calcium Magnesium Acetate have in Common?

  • They are both much friendlier to concrete and asphalt than rock salt
  • They are both pet friendly
  • They are both plant friendly
  • They make an excellent pre-treatment, adhering to pavement and preventing snow or ice from bonding to the pavement.
  • They both can be mixed with rock salt or sand for spreading.
  • They both can be mixed with water to treat surfaces with a brine solution (a salt water solution sprayed on instead of spreading the product on dry)

What is So Great About Calcium Magnesium Acetate (CMA)?

  • There is absolutely no chlorine in CMA.  Chlorine is the primary reason why deicers eat away at pavement and structures they come in contact with.  CMA is about as corrosive as tap water, so very low corrosive properties.
  • CMA has low toxicity to plants and animals and is completely biodegradable.
  • CMA does not create a “runoff brine.”  It tends to sit in place therefore you need to make less applications during a big storm and one application may cover you for multiple periods of freezing moisture.

What Are the Cons of Calcium Magnesium Acetate (CMA)?

  • CMA only melts down to about 15°, the same temperature as rock salt.
  • It is not great at melting snow (rock salt works much better for this purpose).  CMA works better as a pretreatment on pavement to keep snow from sticking.

What is So Great About Magnesium Chloride?

  • Magnesium Chloride melts ice down to a frigid -13°.
  • Magnesium Chloride works fast.
  • Magnesium Chloride tends not to leave residue, so it is great to use in front of building entryways to help limit the mess you often see during winter events.  In other words, when the snow tracked in dries, you do not get a whole bunch of grey film sitting on top of the flooring like with rock salt.
  • Magnesium Chloride helps make dirt roads more compact.
  • Magnesium Chloride is great for keeping dust down and is even used as a dust treatment on roads, at construction sites, and in horse arenas.

What Are the Cons of Magnesium Chloride?

  • There is only about 1/3 the chloride in Magnesium Chloride compared to rock salt, but it still contains chlorine. The small amount of Choride means Magnesium Chloride has a slightly caustic effect on pavement and other surfaces. While it is much less caustic than rock salt, it is still harder on surfaces than CMA.

Which One Do I Use?

If you need the more environmentally friendly ice melt of the two options, then you will want to stick with CMA.  If you need the best performance for your money, Magnesium Chloride is going to be your best bet.

To be sure, we love both products.  They are both environmentally friendly when used properly and they both have a good value for the money you spend when they are used as intended.

Dust Control for Roads, Parking Lots, Work Zones, and Horse Arenas

Keeping Dust Down for Health and Environmental Reasons

We once viewed dust as just an annoyance, but now we know that constantly kicking up dust is bad for people, machines, and the environment.  It wasn’t that long-ago we gave dust little attention, and now, larger construction companies are requiring their people to wear breathing protection where there isn’t dust control because we are beginning to realize constantly introducing people to large amounts of air born particulates creates negative long-term health consequences.  Dust control helps people (and machines) breathe easier preventing problems further down the road.

So, what are effective methods of keeping dust down?  The primary way is to use environmentally friendly “hygroscopic” salts. Hygroscopic is just a fancy word meaning the material attracts moisture from the air and its surroundings.  If you have ever left table salt out on a humid day and then you notice the salt wants to clump together, you have already experienced hygroscopic salts in action.  With environmental dust, hygroscopic salts help the loose dirt essentially stays moister with the hygroscopic salts pulling moisture into the dirt and therefore dirt stays on the ground better when the wind is blowing. After a while, the hygroscopic salts will help the dirt bind together and become compact.  As the salts seep down, they actually create a stabilizing effect which is great for roads because you see lower maintenance costs and less damage from frost and ice.

What Should I use for Dust Control?

The two most popular, environmentally friendly salts are Magnesium Chloride and Calcium Chloride. You can apply them as a brine solution (salt water) or spread them as flakes.  Brine solution is usually the method of choice for road crews and large construction sites because it is quick and easy, but you need a brine sprayer.  A brine sprayer is nothing more than a big tank on a big truck to hold the brine solution plus sprayers on the back to deliver the product onto the ground.  Usually the brine is 33-35% salt but be sure to read the directions of the specific product you will use.

For smaller areas or for those who do not want to buy expensive equipment, we like to recommend getting Magnesium Chloride Flakes.  Flakes are great because the surface area helps it stick to the ground and it won’t roll like pellets do.  To apply flakes, you want to spray down the area with water until it is damp, then spread about 2 lbs of magnesium chloride per square yard immediately afterward while the ground is still damp.  Once the ground dries, add another pound of magnesium chloride per square yard.  That means one 50 lb. bag of magnesium chloride flakes should treat about 150 sq. ft. the first time around.

After that, you can usually apply one pound per square yard as necessary which will be more often in an open area that gets more rain and less often in something like an enclosed horse arena.  With something like a horse arena, you may need to apply more to entryways and less in the center of the arena.

What will my Dust Control do to my Plants?

Treat Magnesium Chloride and Calcium Chloride like fertilizer around your plants.  Magnesium Chloride and Calcium Chloride are non-toxic and will not hurt plants if you get a little near your plants, but too much of anything will kill your plants.  Too much water, too much fertilizer, or too much magnesium or calcium chloride will hurt your plants if you go overboard, but if you get a little on the ground near your plants, it will have no negative affects unless you are dealing with a super sensitive species.

Best Ice Melt

Dowflake Xtra Calcium Chloride Flakes from Snow & Ice Sale & Chemicals Unlimited, LLC

If you are looking for information on the Best Ice Melt, you have come to the right place since ice melt is what we know!  We not only sell it by the ton, we use it in our own snow and ice removal business!

Unfortunately, the telling you “best ice melt” is not an easy straightforward answer.  The variety of ice melts are more like the variety of tools in your toolbox.  You don’t use a hammer to take out a screw and you don’t use rock salt on glare ice at night when the temp has fallen to -10°.

So rather than telling you “the best ice melt,” we will tell you which one is best for which situations.

Safe N Sure Ice Melt Blend from Snow & Ice Salt & Chemicals Unlimited, LLCBest All-Around Ice Melt

If you are looking for a jack-of-all trades ice melt that will work in most situations without breaking the bank, we recommend Safe N’ Sure Ice Melt.  Safe N’ Sure is primarily rock-salt which keeps the price down, yet it mixes in some of the other ice melt chemicals to allow ice melting down to -25°.  If you only wanted to buy one ice melt, this is the one to choose.

Peladow Calcium Chloride Pellets from Snow & Ice Salt & Chemicals Unlimited, LLCBest Cold Weather Ice Melt

Calcium Chloride like in Peladow Calcium Chloride Pelletspenetrates ice 3 times faster than other ice melts because of its exothermic action (it creates heat when interacting with the ice).  While Safe N’ Sure has a little calcium chloride in it, Peladow is 90% calcium chloride.

Nothing comes close to straight up calcium chloride when it comes to knocking out ice at really cold temperatures.  A bonus of calcium chloride is it likes to stay in place to keep ice and snow from freezing on payment during the next storm

Calcium Magnesium Acetate Ice Melt from Snow & Ice Salt & Chemicals Unlimited, LLCBest Low Corrosion Ice Melt

One of the least corrosive ice melts would be Calcium Magnesium Acetate (CMA).  If you have concrete or iron surfaces you would like to preserve from the harsh effects of chloride-based ice melts, this is a great option.  It works down to -15°and cuts through ice really well.

CMA is generally considered safe for plants and petsunless it is overused.  Like calcium chloride, it also likes to stay in place and acts like a pre-treatment for your next storm.

Best Pet Friendly Ice Melt

Many pet owners love PESTELL Paw Thaw Ice Melt, which is made of a sugar based, non-toxic anti-freeze called propylene glycol.  It cuts through the ice yet is no more harmful than if your pet stepped in glycerin.

Rock Salt - Bulk Salt - Solar and Mined Rock SaltBest Cheap Ice Melt

You can’t beat rock saltfor being cheap!  You can normally buy rock salt for a small fraction of the cost of the other deicers.  Yet, you get what you pay for.

Rock salt is corrosive to your concrete and asphalt, harmful in larger quantities to your plants and animals, and only works to about +15°.  You often have to use more rock salt than the other ice melt products, so in the end, you are saving less money than you may hope, but it is still extremely inexpensive.

What is the Most Environmentally Friendly Deicer?

various ice melt chemicals

There is No Perfect Deicer

There are a lot of blog posts out there that tell you they have the “silver bullet” deicer that will melt snow and ice at low temperatures while at the same time be healthy for the environment.  Sorry to tell you, there are no perfect deicers.  Every single type of deicer currently on the market in large enough quantities will negatively impact the environment in one way or another.

Beyond the environmental impact, they all have the potential to corrode our roads (more so with the chloride-based products and not so much with the carbohydrate deicers) and they also don’t all work the same in very cold temperatures (sorry, but nothing beats out Calcium Chloride for breaking up ice in frigid weather).

There are three basic types of deicers out there, and each type has their own strengths and weaknesses.  The three categories we will cover are chloride-based deicers, acetate-based deicers, and carbohydrate-based deicers.

Before we cover those, we should stress that the best way to protect the environment is to not over-salt.  By reducing the amount of salt, you reduce how much of the deicer gets into our soil and into our waterways.  You want to put down just enough deicer (or preventative anti-icing agent) to keep people safe without an ounce more.

Magnesium Chloride Flakes: Mag Flakes: MGCL PRO-F by Hot SaltChloride-Based Deicers

Chloride based deicers are the most common deicers used in the United States and throughout the world with rock salt leading the way.  Rock salt is the same thing as table salt, only in larger grains.  Calcium chloride and magnesium chloride are also popular chloride-based deicers.

All chloride-based products are highly corrosive to metals and moderately corrosive to concrete.  More importantly, chloride-based deicers are harmful to plants, moderately harmful to soil and waterways, yet they at least have little impact on air quality.

In other words, if you put enough salt on your plants, they are going to die.  A little salt in the river won’t hurt anything, but after years of use, salinity starts adding up which can be toxic for aquatic life.

We can say that calcium chloride and magnesium chloride appear to be less harmful to the environment because they can help soil in lower doses by improving soil structure plus you need less of these two than rock salt to break-up ice.  So we can say they are more “environmentally friendly” than other deicers to your soil and they introduce less chlorine into the environment because it takes less volume of either of these two deicers to do the same work as others, allowing you to use less deicing product overall.

Generally, most people do not spread calcium chloride or magnesium chloride by themselves because of the cost as compared to rock salt.  Instead, most people will use them in blends with rock salt allowing for maximum impact while keeping costs reasonable.

Acetate-Based Deicers

Acetate-based deicers do not poison the ground and waterways with chlorine and in small amounts they can act as fertilizer.  The key point is “small amounts.”  Deicers like Calcium Magnesium Acetate (one of our favorites), Potassium Acetate, and Sodium Acetate are moderately corrosive, don’t hurt soil or the air in moderation, but in larger quantities they can be devastating to plants and aquatic life.

What happens is they create osmotic stress (water is pulled out of the cells) when found in larger concentrations in plants and they set off microscopic organism growth which steals oxygen and other resources from affected plant and aquatic life.  This second issue is a similar to what happens when too much farm runoff gets into streams where you see a lot of algae growth, yet the fish may be oxygen starved.

Carbohydrate-Based Deicers

Carbohydrate-based deicers are friendlier to metals and concrete but they do not have a whole lot of power to melt ice in cold temperatures.  Carbohydrate-based deicers are made from beets or other fruits or vegetables and can be pricey for how little work they actually do to remove ice.  Because these deicers have not yet shown a lot of value in cost versus the benefit, most people just avoid them altogether (which is also why we do not stock them).  You are more likely to see these types of deicers as part of a blend then by themselves if you see them in the stores.

Carbohydrate-based deicers have a similar effect upon plants and aquatic life as acetate-based deicers.  The sugars are going to spur the growth of micro-organisms which steal necessary resource for growth from plant and aquatic life.  If you have every mixed in compost into your soil without having let the compost “cook thoroughly” or break down all the way, you may have seen plants you put in that soil struggle or even die.  These carbohydrate deicers can have the same effect in larger concentrations.  While bacteria break down the deicer, they use up nitrogen and oxygen, and if there is too much carb-based deicer in an area, plant or aquatic life can be killed.

You Wonder “What Deicer Should I Choose?”

There is no one right answer since there are pros and cons to every product.  Again, the first step in protecting our environment is generally to just use less deicer.  Apply only as much deicer as is necessary for safety.  If you can, one option is to prevent traffic from certain areas, so you don’t have to apply deicer in those spots at all.  Another option is to use deicer that has a bright color to it, so you will be able to accurately see how much salt you have actually spread.

In the end, the deicer for you will be what fits your personal choice and yet still removes the ice.  One of our personal favorites is Calcium Magnesium Acetate for when temperatures are above 15 degrees.  It is one of the friendliest deicing products available that is commonly found in the market.

When you have colder weather, then Calcium Chloride or a Calcium Chloride blend like Hot Melt are your best options because they can work in very cold temperatures yet it takes a lot less to get the job done (like 2-7 times less depending on the product you are comparing it to).

Commercial Ice Melt for Commercial Ice Removal

Best Ice Melt Distributor - ice salt truck.jpg

Commercial Ice Melt is essential for any serious contractor.  You know that rock salt is great, but it just does not do the trick in all situations.  Like when you get an ice storm followed by really cold temperatures, you need something that can cut through the ice today, not when the weather warms back up.  This is where a large arsenal of commercial ice melts come in really handy.

Some of the best ice-melts are considered “hot melt.”  The difference with hot melt is that it is exothermic, rather than needing heat to melt ice, it creates its own energy.  This means that the hot melt works at much lower temperatures and can be really effective against ice.

Rock-salt is not going away any time soon.  The inexpensive cost to get rock-salt in bulk makes rock salt the primary weapon of choice for melting ice and helping tackle snow.  When the temperatures get really cold, most ice melts use a blend that is about 80% rock salt and 20% something else like magnesium chloride.  The blend helps keep the cost down while the magnesium chloride starts the melting process and the rock salt finishes off the job.

If you are a contractor, you likely already knew all that.  The problem becomes, where do you get commercial quantities of ice melt?  Should you pay way too much at a big box store?  Should you get it from a chemical supply company that primary sells cleaning agents and knows little about which ice melt to use when?

How would you like to buy your commercial ice melt from guys who started a company dedicated to commercial ice melt, guys that have experience pushing snow themselves?

Snow, Ice, Salt: The Three Sisters of Winter

snow & ice salt treatment

Snow, Ice, Salt and Winter

It is hard to think of winter in the Northeast without thinking of our friends: snow, ice, salt. Snow falls on a regular basis. Ice comes from ice storms or from melting snow. Salt follows the other two to keep us safe. The frustration for some people is, with other alternatives, why is spreading rock salt still the primary method for attacking snow and ice. We are glad you asked.

Rock Salt is “Dirt Cheap”

At about $50/ton for bulk rock salt for deicing, it is hard to come close to the cost of rock salt when it comes to fighting ice and snow.  Some other products costs more than 10 times as much to produce compared to what it costs to mine and prepare rock salt for spreading.  Don’t get us wrong, many contractors would be happy to spread the more environmentally friendly products, but their customers want the cheaper product.  So in the end, it is the clients that say price is an important factor in which deicing product is chosen.

Brine Doesn’t “Cut-It”

Brine is great as a pre-treatment or on ice, but when you are dealing with a lot of snow, brine solutions and even some of the dry rock salt alternatives don’t seem to cut through the snow like a good spread of rock salt.  When you have to load your salt spreader with one ingredient to work in the changing situations of a large winter weather event, rock salt continues to be a great, versatile product.

What About Rock Salt’s Bad Reputation?

Rock Salt gets a bad reputation not because it is evil, but usually because it is over-applied.  Contractors that learn to apply the proper amount of salt save money, the environment, roadways, and the properties of clients when they use just the right amount of salt instead of going with the “more is better” theory.  Rock Salt can be combined with other products to be less corrosive and to work in lower temperatures than it does when applied with no treatments.  Leveraging the strengths of rock salt while adding the strengths of other products creates a real benefit where everyone can win.

SIMA has been doing a lot in the industry in order to help contractors know the best spreading methods to minimize use of deicing products, but also to explore how we can do even better in reducing any negative effects of rock salt.  You can learn more about SIMA’s sustainable salt initiative here!
