Drain the fountain.

Allow the fountain to dry for several days in the sun, if possible. This step is not absolutely necessary.

Wipe off the surfaces of your fountain with a wash cloth, warm water and a cleanser. You can use dish detergent, lemon juice, bleach or vinegar to kill the algae. Make sure the cleanser is safe for your fountain.

Use a pipe cleaner to remove algae from any tubing or spouts on your fountain and a toothbrush to scrub any small cracks or areas. Use the same cleanser that you previously used, to remove all the remaining algae from your fountain.

Rinse out the fountain with water.

Refill your fountain with clean water.
