Our Hummingbird Feeder Cleaning Brushes are perfect for cleaning and maintaining your hummingbird feeders! This pack come with three brushes that are sure to get your hummingbird feeder squeaky clean! The long brush is used primarily for cleaning the inside of the hummingbird feeder itself. The longer end of the large brush is used for cleaning the reservoir; the smaller side will allow you to clean the base of the feeder as well as any harder to reach nooks and crannies. The tiny brush with the pointed end is meant for cleaning the ports where your hummingbirds feed from.
