Algae growth on urban outdoor furniture is a common problem, turning beautiful patios and balconies into slippery, green-eyed monsters. Fortunately, removing it and preventing its return is straightforward with the right approach. The best method depends on the furniture material and the severity of the growth.
For a quick and effective clean, a simple DIY solution is often best. Mix equal parts white vinegar and water in a spray bottle. For tougher jobs, add a squirt of eco-friendly dish soap. Spray the solution generously onto the algae-covered surfaces and let it sit for 10-15 minutes to break down the growth. Then, scrub vigorously with a stiff-bristled brush (use a softer brush for delicate woods like teak). Finally, rinse thoroughly with a garden hose. This method is safe for most materials, including metal, plastic, and resin.
For large areas or heavily infested furniture, a pressure washer can be a powerful ally. Use a wide-angle, low-pressure tip and keep the nozzle at least 12 inches from the surface to avoid damaging the furniture. Always test on a small, inconspicuous area first.
To prevent algae from returning, ensure your furniture dries completely after rain by using covers or storing it in a dry place. Applying a specialized outdoor furniture protectant spray can also create a barrier that inhibits new growth. Regular cleaning every few months will keep your urban oasis looking fresh and inviting.
