Algae stains on a wood outdoor table can be unsightly and difficult to remove, but with the right techniques, you can restore your furniture to its original beauty. Here are some effective methods to tackle algae buildup:

1. Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the stained areas and let it sit for 10-15 minutes. Scrub gently with a soft brush or sponge, then rinse with water.

2. Baking Soda Paste: Create a paste using baking soda and water. Apply it to the algae stains and let it sit for 20 minutes. Scrub with a brush and rinse thoroughly.

3. Hydrogen Peroxide: For tougher stains, use a diluted hydrogen peroxide solution (1 part peroxide to 4 parts water). Apply, let it sit for 10 minutes, then scrub and rinse.

4. Pressure Washing: If your table is sturdy, a low-pressure wash can help remove algae. Be cautious to avoid damaging the wood.

5. Preventative Measures: To prevent future algae growth, keep your table dry, store it in a shaded area, and apply a protective sealant.

Regular maintenance and these natural cleaning solutions will keep your wood outdoor table looking pristine for years to come.
