Composite outdoor benches are durable and low-maintenance, but they can develop mildew or algae over time, especially in shady or damp areas. Here's a simple, effective way to restore your bench's clean appearance.
First, remove loose debris with a soft brush or cloth. Then, create a cleaning solution by mixing warm water with a small amount of mild dish soap. For tougher stains, you can use a mixture of one part white vinegar to one part water, or a specialized composite deck cleaner.
Apply the solution with a soft-bristled brush, scrubbing gently to avoid damaging the surface. Let it sit for 10-15 minutes, then rinse thoroughly with a garden hose or low-pressure spray. Avoid using a pressure washer, as high pressure can damage the composite material.
For persistent mildew or algae, you may need to repeat the process. To prevent future growth, keep the bench in a sunny area when possible, and clean it regularly. Ensure proper drainage around the bench to avoid water accumulation.
With these simple steps, your composite bench will stay looking fresh and beautiful for years to come. Regular maintenance is key to preventing stubborn buildup and preserving your outdoor furniture's appearance.
