Dos and Don’ts for Cleaning Your Snow-Covered Deck

A composite deck is an investment built to last through rain, ice and snow. Fiberon’s outdoor composite decking is scientifically tested to ensure your outdoor project can sustain extreme weather changes. (Check out our freeze/thaw test results to see just how sure we are!) The one thing we can’t account for is human error. That’s why it’s so important to research and understand the proper, minimal care your composite decking needs.


Snow on a Fiberon Composite Deck

One topic we get a lot of questions from homeowners about, is what to do when your deck is covered in ice or snow. First, let’s start out with what you should do during extreme cold and then move on to things you should avoid.

Use Calcium Chloride-Based Ice Melt

The best tool for removing ice and snow is a calcium chloride-based “ice-melt” or rock salt. If you’re unsure about what type of ice-melt you’re looking for, search for a product that has the phrases, “safe for concrete”, “safe for flagstone”, and “will not kill grass” in its description.

It’s important to note that Calcium Chloride ice melt can cause harmful effects. If you have kids or outdoor pets, you’ll want to keep them away from the treated area.

Clearing Debris

Once you’ve treated the existing ice and snow, give the process time to work. When the threat of inclement weather has passed, use a broom to sweep up any existing granular pieces (help protect water and wildlife by throwing away the ice melt). This will also prevent people and pets from unintentionally tracking in ice melt which can damage your home.

Rinse Your Deck

You may not be able to completely clear off your deck during the winter months. (See below for reasons why you shouldn’t try forcibly removing ice and snow) Once the weather gets warmer, use a garden hose to rinse off any remaining debris and ice melt from your decking.


What To Avoid



  • Do not use ice melt with an added colorant. The dyes can stain your composite decking.
  • Never use sand on Fiberon Decking. Sand abrasion can grind into the decking and permanently damage the surface.
  • Brooms are best. Do not use metal shovels or sharp-edge tools to clear your deck.
  • Be extremely careful when pressure washing your deck. Set your pressure washer to 1,500 psi or lower and maintain a safe distance (12” above deck or more to avoid damaging your deck.)
