CLEANING YOUR FEATHER DUSTER DRY CLEANING METHOD To clean your feather duster, simply take it outside and shake it to release the dust. WET CLEANING METHOD If you have more than just dust in your feather duster (ie: food, etc) then you may need to wash your duster. This is fine...after all these are bird feathers! Fill a bucket or sink full of warm water and a little dish washing soap. Place your duster in the solution and let it soak for a minute, and then gently swish the duster back and forth. Afterwards rinse the duster in fresh water. Finally, to dry it, squeeze and shake out excess water, and then let it air dry while hanging upside down. Once it is dry, turn it right-side up and wave your hand through it to fluff up the feathers.
