Put one cupful of corn meal, one-half cupful of white flour and three tablespoonfuls of powdered borax into a paper bag and shake the feathers in this till clean, then remove and shake. This also cleans laces, etc.
Feathers are also cleaned by dipping in gasoline, rubbing the feathers toward the tip, then shaking dry. This does not take out the curl. Never use gasoline indoors.
Make a paste of flour and gasoline. Put the feather in it and rub carefully the entire length, toward the tip. Repeat till clean. Rinse in clear gasoline and shake dry.
Sprinkle salt over hot coals, and shake the feathers over them.
Or place the plume in a warm oven for a few minutes.
