A dirty bird feeder does more harm than good. Wet seed and hull debris trap mold and bacteria, and a feeder that never gets scrubbed can spread diseases like salmonellosis and avian conjunctivitis through a backyard flock fast. The good news is that cleaning one properly takes about ten minutes and only a handful of supplies you probably already have.

What You Need

  • A bucket or basin big enough to submerge the feeder
  • Dish soap and a bottle or stiff-bristle brush (a bottle brush works well for tube feeders)
  • White vinegar or a mild bleach solution (1 part bleach to 9 parts water)
  • Rubber gloves
  • A towel or drying rack

Step 1: Empty and Disassemble

Dump out any leftover seed, especially anything wet, moldy, or clumped. Take the feeder apart as far as it will go, ports, base, perches, and lid, so water can reach every surface.

Step 2: Wash With Soap and Water

Scrub every part with warm soapy water, paying extra attention to feeding ports and corners where hulls and droppings collect. A bottle brush gets into tube feeders that hands cannot reach.

Step 3: Disinfect

Soak the parts for 10 minutes in a 10% bleach solution (about 1 cup bleach per gallon of water), or use straight white vinegar if you would rather avoid bleach. This step is what actually kills mold spores and bacteria that soap alone leaves behind.

Step 4: Rinse and Dry Completely

Rinse thoroughly under running water until you cannot smell bleach or vinegar anymore, then let every part air-dry fully before refilling. Wet seed inside a feeder is exactly the moldy mess you just cleaned up, so patience here matters.

How Often to Do This

Clean every 2 weeks in normal conditions, weekly in hot, humid, or rainy weather, and immediately if you notice sick or dead birds nearby. Wipe up spilled seed on the ground regularly too, since it molds just as easily as seed left in the feeder.
