How to Clean Algae from Patio Furniture

Remove algae from patio furniture using a mixture of bleach and water or white vinegar, scrubbing with a soft brush, then rinsing thoroughly and allowing to dry completely.

1. Set Up Your Workspace. Relocate your patio furniture to a concrete driveway, lawn area, or other space where you can work freely and rinse without worrying about runoff. Choose a shaded spot if possible to prevent cleaning solutions from drying too quickly.
2. Clear Away Everything Loose. Brush off any loose dirt, leaves, or debris with a dry brush or cloth. Remove all cushions, pillows, and fabric elements, as these require separate cleaning methods. Check manufacturer labels on fabrics before treating.
3. Mix Your Secret Weapon. Mix one part bleach with nine parts water in a spray bottle for heavy algae growth, or use undiluted white vinegar for a gentler, eco-friendly option. For mild cases, dish soap mixed with warm water works well. Always wear gloves and work in a ventilated area when using bleach.
4. Saturate the Algae Spots. Spray the affected areas generously with your chosen solution. For stubborn algae spots, apply the solution and let it sit for 10-15 minutes to break down the growth. Avoid letting bleach solutions sit too long on colored or painted surfaces.
5. Scrub Every Hiding Spot. Use a soft-bristled brush or sponge to scrub the algae from the furniture surface. Work in circular motions and apply moderate pressure. For textured surfaces or crevices, use an old toothbrush to reach into corners and grooves where algae often hides.
6. Flush It All Away. Spray down the entire piece of furniture with clean water from a garden hose, ensuring all cleaning solution and loosened algae are completely removed. Pay special attention to joints, crevices, and any areas where solution might pool.
7. Dry and Check Results. Allow the furniture to air dry completely in the sun, which helps prevent algae from returning. Inspect for any remaining algae spots and repeat the cleaning process on stubborn areas. Once fully dry, return cushions and accessories.
