The Use of Ice Melt for Exterior Decking

Ice on Composite Decking

• Composite decking manufacturers suggest the use of calcium chloride or rock salt to melt the ice and snow from its decking product. Some companies recommend using a gentler product that states it does not harm concrete or grass. Brush off any leftover ice melt after the snow and ice melts to protect the deck.

Ice on Wood Decking

• Wooden deck manufacturers suggest using a salt-free, pet-safe ice melt to melt the ice and snow from your decking. This product is gentler and less corrosive. It should not harm the wood, if it's safe for use around pets.

Other Methods of Ice Removal

• Decking manufacturers recommend dislodging the ice gently from the deck with a plastic or rubber-tipped shovel, but do not use a metal shovel. Shovel with the grain and don't dislodge frozen, stuck pieces of ice, just loose pieces, to prevent scratching or denting the decking. To melt the ice, pour hot water mixed with a few drops of dish washing detergent onto the decking.

Warnings and Suggestions

• Do not use most rock salt products on a wood deck, since it is corrosive and can cause the wood to dry out. It may also stain your decking. Most composite decking products do not require any sealants, but seal your wood decking in the fall before it knows to protect it through the winter months. Wash both types of decking products with a commercial deck cleaner or a detergent and water solution before winter hits.
