I hang mine in the back of the shower and let it soak in the steam from when I shower. Now that it's getting colder, the house heat is on so the strop will be dry by the next time I shower. Depending on the level of the crease, I leave the strop in there for a week or so, repeating the process of hot steam and house heat. It works very well. I then the condition the strop and my strop is ready for use. :)
I'm getting strop #3 and that's what I'm going to do.
