Low-Pressure Cleaning for Composite & Synthetic Decking

Composite decking can develop mold and mildew when environmental spores encounter moisture and an available food source. Even though composite decking is often marketed as low-maintenance, no composite decking product is completely immune to mold and mildew growth. Grime Busters Power Washing provides professional composite deck cleaning to help restore the original beauty of your deck and remove unwanted surface growth.

Our composite deck cleaning service can be performed on decks made entirely from composite materials or on outdoor spaces combining composite with wood, metal, vinyl, or glass. We use very low pressure along with cleaning solutions that are allowed to dwell before the deck is thoroughly washed. The old Grime Busters service page specifically notes that composite deck cleaning works best in direct sunlight and warmer temperatures.

Why It Matters

Protect the Appearance of Your Outdoor Living Space

A composite deck can become noticeably less attractive when mold, mildew, dirt, and environmental buildup accumulate across the surface. Regular professional cleaning helps restore a cleaner appearance and allows you to enjoy your outdoor living area without the neglected look caused by unwanted growth.

Composite and synthetic decking require an appropriate cleaning approach. Grime Busters uses very low pressure combined with cleaning solution and controlled dwell time rather than relying solely on aggressive pressure. This approach is designed around the characteristics of composite decking and can also accommodate decks containing a combination of materials.
