Composite Deck Maintenance Guide: How to Keep Your Deck Looking New

Although composite decking requires less maintenance than wood, regular cleaning and simple care will help keep your deck looking beautiful for many years.

1. Regular Cleaning

The easiest way to maintain a composite deck is regular cleaning. Dirt, dust, pollen, and leaves can accumulate on the surface over time.

To clean your composite deck:

• Sweep the deck regularly with a soft broom

• Rinse the surface with a garden hose

• Use warm water and mild soap if needed

• Gently scrub with a soft brush

Regular cleaning prevents stains and helps maintain the deck’s original appearance.

2. Remove Mold and Mildew

In humid climates or shaded areas, mold or mildew may develop on outdoor surfaces. Composite decking is resistant to mold, but dirt buildup can still allow mildew to form.

To remove mold:

• Mix warm water with mild dish soap

• Scrub lightly with a soft brush

• Rinse thoroughly with water

Avoid harsh chemicals or strong pressure washing that could damage the deck surface.

3. Avoid Scratches and Damage

Composite decks are durable, but it is still important to protect the surface.

Helpful tips:

• Use furniture pads under chairs and tables

• Avoid dragging heavy furniture across the deck

• Use a plastic shovel when removing snow

These simple steps help prevent scratches and surface damage.

4. Clean Spills Quickly

Food, grease, and drink spills can leave stains if left for too long.

If something spills:

1. Wipe the spill as soon as possible

2. Wash the area with warm soapy water

3. Rinse with clean water

Prompt cleaning keeps your composite deck looking fresh.

5. Seasonal Inspection

It is a good idea to check your deck at the beginning of each season.

Look for:

• loose fasteners

• dirt buildup between boards

• blocked drainage gaps

A quick inspection helps prevent long-term issues.
