I have started collecting ties and some of them were pretty grotty. I actually deconstructed mine before washing and gently handwashed with liquid wool detergent, then rinsed with cheap white vinegar and water and hung out to air dry. Anything that didn't survive that was ditched, I had a theory that if I pulled them apart first I could assess usability and had no use for the lining so couldn't see the point in washing it. Oh and I didn't soak them for long.
