How to clean algae buildup from aluminum outdoor flower pots?

Algae buildup on aluminum outdoor flower pots can make them look dirty and unsightly. Fortunately, cleaning them is simple with the right methods. Here’s how to restore your pots to their original shine:

1. Prepare a Cleaning Solution – Mix equal parts white vinegar and water in a spray bottle. Vinegar is a natural disinfectant that helps break down algae.

2. Scrub Gently – Use a soft brush or sponge to scrub the affected areas. Avoid harsh abrasives to prevent scratching the aluminum.

3. Rinse Thoroughly – After scrubbing, rinse the pot with clean water to remove any residue.

4. Prevent Future Growth – To reduce algae recurrence, place pots in well-ventilated areas and avoid overwatering plants.

For stubborn algae, a mild bleach solution (1 part bleach to 10 parts water) can be used, but rinse thoroughly afterward. Regular maintenance will keep your aluminum pots looking great all season!
