How to clean a bird feeder

Clean food starts with an accessible feeder. Use this checklist with the exact manufacturer’s instructions, especially for electronics, coatings and removable parts.

    Let the washable parts dry before adding fresh food.

Choose seed or nectar below for the right schedule and cleaner guidance. Use a dishwasher only when your exact feeder’s manual permits those parts.

A checklist you can keep

Seed and nectar have different schedules

Project FeederWatch recommends cleaning seed feeders every week or two, and more often in wet weather or heavy use. Remove spoiled food and debris from below the feeder as well as from the reservoir. Let washable parts dry completely before adding seed.

Nectar needs much more frequent attention. Audubon gives daily or every-other-day cleaning in hot weather, every three days in temperate weather, and twice weekly in cooler conditions. Cloudiness, mold or a sick bird’s visit calls for prompt action.

Keep water and cleaners away from electronics

Remove the camera, battery and other electrical parts as the exact manual directs. Weather resistance is not permission to submerge a camera or place it in a dishwasher. Clean the lens and ports only as the manufacturer specifies.

Cornell and Audubon give different cleaner guidance for nectar feeders. The checklist shows that difference instead of treating one cleaner as universally correct. Follow the material-specific instructions and rinse thoroughly.

When birds appear unwell

Check your state wildlife authority for a current advisory. Cleaning, appropriate disinfection and temporary removal may be relevant, but conditions vary. Do not handle sick birds or use this checklist to diagnose them.

Keep records of a concerning observation for the relevant wildlife organization, and follow its current instructions.
