How do I clean old fly tying materials?
The Blue Dawn Ultra Dishwashing Liquid, Original Scent does a wonderful job of removing any dirt, oil, fats, or residue that may have soiled the material.
Start by soaking the feathers or materials in warm water and work in a liberal amount of liquid soap.
Rinse them thoroughly with cool water, and pat them dry with paper towels. Let the air dry on a rack or hang them on a close line to dry.
For faster drying use a hair dryer and use your fingers to stoke the material back to its original shape.
