What can you use to clean the sides of your pool from algae that does not contain chlorine?

There are several chlorine-free alternatives that you can use to clean the sides of your pool from algae. Here are a few common options:

1. Vinegar: White vinegar is a natural and mild acid that can effectively kill algae. To use vinegar, create a mixture of 50% water and 50% vinegar. Spray this solution directly onto the algae spots and scrub with a brush. Leave it for about an hour, then rinse the area thoroughly.

2. Baking Soda: Baking soda is another gentle abrasive that can help remove algae from pool surfaces. Make a paste by mixing baking soda with a small amount of water. Apply the paste directly to the algae, scrub with a brush, and leave it for several hours or overnight. Rinse the area thoroughly afterward.

3. Borax: Borax, also known as sodium borate, is a natural mineral that has antifungal and antibacterial properties. To use borax, dissolve it in water according to the package instructions and apply the solution to the algae-affected areas. Scrub with a brush, leave it for a few hours, and then rinse well.

4. Hydrogen Peroxide: Hydrogen peroxide is a powerful oxidizer that can kill algae and other microorganisms. Mix equal parts of hydrogen peroxide and water and apply it to the algae. Let it sit for about 30 minutes, then scrub the area and rinse thoroughly.

5. Oxygen-Based Cleaners: Some commercial oxygen-based pool cleaners are designed to remove algae without the use of chlorine. These cleaners typically contain hydrogen peroxide or other oxidizing agents. Follow the manufacturer's instructions when using these products.

6. Algaecides: There are also specific non-chlorine algaecides available that can be used to target and kill algae growth in your pool. Follow the instructions on the algaecide container carefully when using them.

It's important to note that while these alternatives may be effective in removing algae, they might not provide long-term protection against algae growth. Regular maintenance and proper pool chemical balance are still essential for keeping your pool clean and free from algae.
