I have been told just rinse the flys off with fresh water. This seems to work about half the time. They still get rust on them. The worst part seems to be right at the pinched down barb. I also tried soaking them but it bleeds the color out of them. I use Gamakatu saltwater hooks for all my ties. I love to tie flys but when you have caught a few fish with a curtain fly you get the sense that it has some sort of mystical and magical powers and would like to save it and use it on your next trip. Does anyone have ideas on how to better to clean flys after a hard day of saltwater fishing. Thanks, later.
