same here buy back up socks and clean the old ones with some bleach, then what i do is run it again in the wash right after to get all the bleach off of them
I had extras so I would just dump them in a bucket with water, and a little bleach until I was down to the last one.
I'd run the dirty ones through the wash with a little chlorine, and hot water on double rinse twice. Then dried them.
Don't use them anymore! To much of a hassle, caused to many floods for me with my set up.;(
