Getting dust off a feather lampshade can be tricky as there are millions of barbs that can trap dust. With some DIY tricks, you can clean this without ruining the lampshade. The easiest way is to use a hairdryer. Just point the hairdryer at the feathers and turn it on. Rotate the shade when you are blowing to dislodge the dust from the insides of the feathers. This step will do the job of cleaning all the loose dust. After that, you have to deal with more stubborn dust. For this, use a soft-bristled brush and run it gently through the feathers.
