Introduction
Composite decking is one of the most popular upgrades for modern homes—but it also requires a completely different cleaning approach than traditional wood.
If cleaned incorrectly, you can:
- Permanently damage the surface
- Cause discoloration
- Void your manufacturer warranty
In this guide, we’ll show you:
- What NOT to do
- The safest cleaning methods
- How to protect your investment
Why Composite Decks Are Different
Composite decks are made from:
- Synthetic materials
- Wood fibers
- Protective coatings
They are designed to be durable—but not indestructible.
The #1 Mistake: Pressure Washing
Using high pressure can:
❌ Damage the surface
❌ Leave visible streaks
❌ Strip protective coatings
The Right Way: Soft Washing
Soft washing:
- Uses low pressure
- Applies proper cleaning solutions
- Cleans without damage
Why Detergent Matters
Using the wrong cleaner can:
- Discolor the deck
- Break down materials
Professional solutions are designed specifically for composite surfaces.
