A whistling tea kettle works better than  just an open pot for steaming feathers.

Once washed with dishsoap removes the natural oils and haven't found a way yet to restore them....

If staft still good, I just refletch...

Here is one from Saturday. I wash it under warm water (since I use fletching tape) If you used glue to fletch you could use hot water.  I take a tooth brush and wash hold them under the water and go back and forth with the brush until the blood is gone. Then I just whip the arrow back and forth a few times to sling off the water. I then take my finger and go backwards on the feathers to fluff them up. Then just put them up to dry overnight.

Then I rub the feathers from front to back a few times. They are still separated somewhat but fly just fine.

I use dawn dish soap  ,, then steam fletching ,, same as most if they are tattered I just refletch
