Algae growth on a stone outdoor table is a common issue, especially in humid or shaded areas. Not only does it make the table look unsightly, but it can also become slippery and hazardous. Fortunately, there are several effective ways to remove algae and prevent it from returning.

1. Natural Cleaning Solutions

- Vinegar and Water Mix: Combine equal parts white vinegar and water in a spray bottle. Spray the solution onto the algae-covered areas and let it sit for 15-20 minutes. Scrub with a stiff brush and rinse thoroughly.

- Baking Soda Paste: Make a paste using baking soda and water. Apply it to the algae, let it sit for 10 minutes, then scrub and rinse.

2. Chemical Cleaners

For stubborn algae, use a commercial algae remover or a bleach solution (1 part bleach to 4 parts water). Apply carefully, avoid surrounding plants, and rinse well after scrubbing.

3. Preventive Measures

- Regularly clean your table to prevent algae buildup.

- Place the table in a sunny spot, as algae thrive in shade.

- Apply a stone sealant to create a protective barrier.

By following these steps, you can keep your stone outdoor table clean and algae-free all year round.
