Restoring a weathered teak garden bench is a rewarding project that brings its warm, golden hue back to life. First, clear the surface with a stiff brush to remove loose debris. For a deep clean, mix a solution of warm water and mild teak cleaner or dish soap. Scrub the wood thoroughly with a soft-bristle brush, following the grain. For stubborn mildew or gray stains, a specialized teak brightener can be used. Rinse completely with a hose and let the bench dry fully in the sun for at least 48 hours.
Once dry, lightly sand the entire bench with 120-grit sandpaper to remove the remaining gray surface and smooth any rough spots. Always sand along the wood grain. Wipe away all sanding dust with a tack cloth.
The final step is protection. Applying teak oil is optional but recommended if you prefer a richer, honey-colored finish. Using a clean cloth, apply a thin, even coat of high-quality teak oil. Allow it to penetrate for 15 minutes, then wipe off any excess to prevent a sticky film. Let the bench cure for 24 hours before use. For long-term care, repeat this cleaning and oiling process once or twice a year to maintain your bench's beauty and durability.
