To remove mildew from the hummingbird feeder bottle, place a bunch of small nails inside the bottle. Add a little hot, soapy water and gently shake the nails back and forth across the inside edges of the bottle. The nails will loosen all the mildew buildup.
Empty the nails into your hand, rinse well and spread them on a paper towel to dry. Store in a small container and use when cleaning your feeder.
