It's a common question for garden owners: Is it okay to pressure wash my wooden garden benches? The short answer is yes, but with extreme caution and the correct technique. A high-pressure washer can be a powerful tool for blasting away dirt, moss, and mildew, but used incorrectly, it can severely damage the wood by splintering the surface, opening the grain, and forcing water deep into the wood, which leads to rot.
The key is to use a low-pressure setting or a wide fan tip, and keep the nozzle at least 12-18 inches away from the wood surface. Never use a concentrated, high-pressure stream directly on the wood. Always test on a small, inconspicuous area first. For heavily soiled benches, consider using a dedicated wood cleaner and a soft brush first, rinsing with a garden hose. This is often safer and equally effective.
After any wet cleaning, allow the bench to dry completely in the sun. Once dry, applying a fresh coat of sealant, oil, or stain is crucial to protect the wood and restore its beauty. Regular, gentle cleaning and annual sealing are far better for your bench's long-term health than occasional aggressive pressure washing. Treat your wooden furniture with care, and it will provide comfort and charm for many more seasons.
