Remove leaves and other debris from the pump’s intake valve and housing. With the pump taken out of the fountain, wipe it clean with a damp cloth. Use a toothbrush to scrub hard-to-reach areas. Flush the pump and hose lines if they appear to be clogged. Replace filters or damaged components as necessary.
Algae: The tiny organism can flourish in outdoor fountains, particularly in direct sunlight during the peak summer months. Gently scrub it away with a diluted bleach mixture. Thoroughly rinse the fountain afterward. You also can add all-natural products to the water to keep algae in check. These items are rich in enzymes that inhibit algae growth but do no harm pets or other animals. Animal waste: Birds are frequent visitors to outdoor fountains, and while they’re often bright additions to the landscape, they can be messy. Wipe bird droppings away with a damp sponge but try not to use soap. Consider replacing the water, too. Mineral deposits: Hard-water stains often appear on the fountain surface as crusty, white buildups. Scrub these off with white vinegar and allow the fountain wash the deposits away.
