You must remove snow, dirt and stain from the top of your plastic wood decking. Melting snow can be a daunting task if you don’t know-how. Can I use salt to melt snow on composite decking?

Melting Snow with Salt

One way you can get rid of snow from the surface of your composite decking is by using salt or calcium chloride. Of course, there are several ways to remove snow from your decking surface, but those methods require the use of lots of muscle strength. Also, shovelling snow when it has already become ice will be difficult. 

If there is snowflake or ice on your outdoor patio, you can easily use salt to melt it. Rock salt or halites are types of salt you can use to melt snow. They work by reducing the temperature of the snow or ice to 15 degrees. When the ice gets to that low temperature, it will melt gradually, and your decking will be free of snow. Aside from rock salt or halites, there is calcium chloride. 

Calcium chloride is more efficient than rock salt and halites. It will interact with the snow and bring the temperature down to minus 25 degrees. There are lots of salt that you can use, and they vary according to the brand. Happy Paw snow melter claimed to be safer than calcium chloride because it is safer for the pet.

Other Ways to Remove Snow from Your Decking

After it has snowed and your decking is covered, you can use a shovel to remove the snow to make your decking safe. Utilising a shovel is one of the most effective ways of removing snow from your composite decking surface if you don’t want to melt it. But using a shovel comes with a caution.

But if you shovel perpendicular to the boards, the shovel can scratch the surface. You should remove snow from your decking little by little to make the task easier for you.

Aside from a shovel, you can use a broom to remove snow if it is not too deep. After a light snow shower and your decking surface is not fully covered with snow, you can sweep the top of your decking with a broom.
