Safe deicer products for wood or composite decks
Enjoy your deck and move about safely using CMA to remove the ice.
DO NOT use salt or calcium chloride on your wood or composite deck which can corrode the fastners and hardware!
Salt or any chloride-based products are very corrosive to metal and you can put your entire family at risk if you put salt or calcium chloride on the deck. It's hard on the wood but you are inviting disaster from corroded joist hangers, nails, screws etc. Worse yet, there could be electrical conduits or gas pipes running below, out of sight and corroding slowly until it's too late. There have been several cases of decks collapsing from using salt. If you have used salt in the past, have your deck inspected for any signs of corrosion and make recommended repairs.
Q: "What can I use to melt ice or snow on my wood or composite deck without hurting the wood or decking materials?"
A: Finally, an ice melting product that is the safest for your wood deck or composite deck, as well as pets. Great for wooden paths or bridges too!
Calcium magnesium acetate (CMA) is a deicer and can be used as an alternative to rock salt. It is approximately as corrosive as normal tap water, and in varying concentrations can be effective in stopping ice from forming down to around -27.5 °C (-17.5 °F) (its eutectic temperature.) (From Wikipedia)
CMA is produced from a reaction of a magnesium/calcium compound with glacial acetic acid. (vinegar compounds) It is reacted with dolomite or dolomitic lime, to produce CMA.
Lowest corrosion product of anything on the market, even is good for vegetation! Salt, Magnesium Chloride, Calcium Chloride or any commercial products with those ingredients are corrosive and can damage the hardware that holds it all together. Additionally, Calcium Chloride has a more severe freeze/thaw cycle that can contribute to nail popping, splitting or cracking the decking materials, and refreezing to black ice. It is very hard on your skin, eyes, leather, fabric and more.
CMA is a bit unique, it does not produce your typical brine that flows across the surface. Rather, it stays fairly close to where you put it, so you need to spread it as evenly as you can, but sparingly. CMA lasts a long time because it does not run off. Therefore it builds up with subsequent applications, so less and less is needed over time. It is 100% biodegradeable, over 50 degrees for it to break down. Being vey light weight, it does not take a lot do get the job done.
Not only will this melt the snow and ice, it also provides anti-stick properties. Ice and snow do not readily bond so removal is easy. No more corrosive than tap water! See the article at Wikipedia here

Takes very little to effectively pre-treat a large area for super easy ice and snow removal. Snow and ice just won't stick, yet improves traction for vehicles and pedestrians. A real benefit is that the surface of the concrete is being defrosted even while the snow accumulates, reducing the slipperyness. Buys you some time if you can't get to shoveling or plowing right away.
This particular sprayer applies a 4 foot path for sidewalks. (adjustable to 15 feet wide) Notice it only takes a very fine misting to be effective - very economical!
At brisk walking speed we're applting only 1/2 gallon for 1000 square feet. Apply up to 7 days ahead of bad weather for ongoing protection
