How to Clean Mold Out of Glass Hummingbird Feeders


With wings that flap at a rate as fast as 80 times per second, hummingbirds are always an awe-inspiring sight. Many like to attract these tiny birds to their home for the sheer joy of catching a glimpse of them in motion. Hummingbird feeders, like anything else that is exposed to moisture and warmth, can potentially accumulate mold, which is not only unsightly to look at but unhealthy for you and your quick little friends. Fortunately, cleaning it out is easy, so next time your local hummingbirds come by for a quick snack; they'll never even know it was gone.

Step 1

Take the feeder down from wherever you had it hanging.

Step 2

Empty the liquid contents and wash them down the drain in the sink.

Step 3

Mix 1/4 cup of chlorine bleach with a gallon of warm water in a bucket.

Step 4

Set the feeder in the solution making sure that it is completely submerged.

Step 5

Allow the feeder to soak for an hour.

Step 6

Remove the feeder from the solution and use a brush to remove any residual mold.

Step 7

Rinse the feeder with clean warm water.

Step 8

Refill the feeder with the hummingbird food of your choice and hang it back up.
