Said to be the Best Hummingbird Feeder Ever!! Introducing the new solution for cleaner feeders. Dishwasher safe (place all parts of the feeder in the top rack of the dishwasher). When using soap to hand wash the feeder, or when using a dishwasher, always follow up by rinsing with a mild bleach and water solution to rinse the parts before re-filling with sugar and water. Unique 2 piece base. Innovative flow-control design. High-quality removable parts. Bee resistant inner base. Finally you can clean the inside of a hummingbird feeder. Wide mouth jar for easy cleaning and no mess when adding sugar and water. No drip design even in high winds!
