We recently purchased a new high tech clothes dryer that has a steam sterilize option. It really rejuvenates down and takes away any funky odors. Everything comes out super fluffed, clean and fresh without ever getting the down wet, at least saturated. I have run all of my down coats, quilts, etc. through it and it has worked great. Just an FYI. If you have such a machine, it might be a good option.
