My method is this.
When I take them out I turn them inside out and rinse them right away to get the big stuff. This usually makes the run off run greenish for a few seconds.
When I am ready to wash I just fill up my 5 gallon bucket used only for this with 10-1 Bleach and hot water. I usually use even more water than that.
Let it sit for 1-2 days, then I rinse like you wouldn't believe and air dry. Sometimes I place them in front of my fan if I am in a hurry but not usually since I have 3 pairs.
I purchased the eShopps X-Large Square Socks Holder with 2 socks and they were put in Tuesday morning and will come out probably Saturday. I used to have only one at a time for both inputs until I purchased a new 75Gal and built a new sump and it was a new sock every 2-3 days. Ughhh
Note: The eSopps socks have to be bleached or cleaned however you do it or the skimmer will go nuts. My Aqueon socks never had to be just the eShopps. The squares are huge. The holder is enormous. I will post a build sort of, of the new sump. I made a custom bubble trap outside the sump.
