Birdbaths are a valuable addition to any garden, providing a safe drinking spot for birds as temperatures rise in spring. However, sunny weather can cause algae to grow rapidly, making the water hazardous. James Theodore from Water Fountain Online recommends white vinegar as a safe, effective cleaner.
Unlike bleach, which is toxic to birds and can damage their feathers, white vinegar is a natural acid that removes algae without harming wildlife. To clean, mix nine parts water with one part white vinegar (or equal parts for stubborn algae), pour into the empty birdbath, and leave for 10–15 minutes.
After soaking, scrub with a sponge or brush, then rinse and let the birdbath dry in the sun. UV light acts as a natural sanitiser. Clean weekly or every few weeks to prevent algae buildup. Avoid using bleach or pennies, as these can be dangerous to birds.
