How to remove snow from your composite decking

Snow on composite decking can create slippery surfaces and damage the deck if not handled properly. Removing snow safely and effectively helps maintain the deck’s appearance and longevity. This guide explains the best tools to use, how to clear snow without causing harm, which salt products are safe, and what to avoid during winter maintenance.

Types of Shovels and Brushes for Snow Removal

Choosing the right tools makes snow removal easier and protects your composite decking from scratches or stains.

Shovels

• Plastic Shovels

Plastic shovels are lightweight and less likely to scratch composite decking. Look for shovels with a wide, flat blade to push snow rather than dig into the surface.

• Rubber-edged Shovels

These shovels have a rubber strip along the blade edge, which helps prevent damage while scraping snow and ice.

• Avoid Metal Shovels

Metal blades can easily scratch or gouge composite decking. Avoid using metal shovels or those with sharp edges.

Brushes

• Soft-bristle Snow Brushes

Brushes with soft synthetic bristles are ideal for sweeping snow off without damaging the deck. They work well for light snow or after shoveling.

• Push Brooms with Nylon Bristles

For larger decks, a push broom with nylon bristles can clear snow efficiently. Avoid stiff or wire bristles that can scratch the surface.

How to Shovel and Brush Snow Off Composite Decking

Proper technique reduces the risk of damage and makes snow removal more effective.

1. Start Early

   Remove snow soon after it falls to prevent ice buildup.

   
   

2. Push, Don’t Dig

   Use a plastic or rubber-edged shovel to push snow off the deck instead of scraping or digging. This reduces the chance of scratching.

   
   

3. Work in Sections

   Clear small areas at a time to avoid heavy snow buildup that’s harder to remove.

   
   

4. Use a Soft Brush for Remaining Snow

   After shoveling, sweep away thin layers or patches of snow with a soft-bristle brush.

   
   

5. Avoid Excessive Force

   Don’t press hard on the deck surface when shoveling or brushing. Composite decking can scratch or dent under pressure.

   
   

6. Clear Snow from Deck Edges and Railings

   Snow can accumulate on edges and railings, causing moisture buildup. Brush these areas gently.

Types of Salt That Can Be Used on Composite Decking

Salt helps melt ice but some types can harm composite decking or surrounding plants.

• Calcium Chloride

This salt melts ice quickly and is less likely to damage composite decking. It works well in very cold temperatures.

• Magnesium Chloride

Magnesium chloride is gentler on decking and plants. It is effective at lower temperatures and less corrosive.

• Avoid Rock Salt (Sodium Chloride)

Rock salt can cause surface damage and discoloration on composite decking. It also harms nearby vegetation.

• Use Salt Sparingly

Apply salt only where ice forms and avoid overuse. Excess salt can leave residue and cause long-term damage.

What Not to Do When Removing Snow from Composite Decking

Knowing what to avoid helps protect your deck and keeps it looking good.

• Don’t Use Metal Shovels or Scrapers

Metal tools can scratch and gouge the decking surface.

• Avoid Using Wire Brushes or Stiff Bristles

These can wear down the deck’s protective layer.

• Don’t Use Hot Water to Melt Snow

Hot water can cause rapid temperature changes that may warp or damage composite decking.

• Avoid Harsh Chemicals

Bleach or strong cleaners can discolor or degrade the deck material.

• Don’t Let Ice Build Up

Ice left on the deck can be slippery and harder to remove later. Regular snow removal prevents thick ice layers.

• Don’t Use Excessive Salt

Too much salt can leave stains and harm plants near the deck.

Final Thoughts on Snow Removal for Composite Decking

Proper snow removal is essential for maintaining composite decking's integrity in winter. Use plastic shovels, apply traction aids, and establish a routine to prevent damage and ensure safety throughout the season. Regular inspections post-winter are also important.
