How to deodorize goose feather pillow core? Can I wash it?

Don't dry clean it, just rinse it with water. Put some toilet water in it. It's best to wash it by hand, and don't twist it hard, which makes the goose feathers messy. Sun drying, usually when not in use, will slowly remove the smell of goose feathers. Don't use perfume. It's useless, but it will stink even worse. Goose feathers smell terrible. Good goose feather products also have a taste, but they are very small.
