Just a quick update on my recent sock cleaning experience. Some have suggested washing without bleach. I tried that, and after a lot of washing and rinsing, they were still not clean. These 200 micron CPR socks are too thick and stiff to turn inside out, so it is very difficult to wash loose the crud that is stuck in the fibres.
I then soaked them in a bucket with some bleach for a couple days. And almost like magic, the crud was dissolved and easily washed out, clean and white. It took a couple more cycles of rinsing in clear water and then drying to get rid of the bleach smell. But at the end of a week, they were ready for use again.
These large socks easily last a week for me, so a weekly cycle is just the right amount of time to get them cleaned and ready for use again.
Thanks again to everyone for all your suggestions.
Also, for your interest, here are a couple pics of the sock hangar I made out of a scrap piece of lexan. I like working with lexan, as it is easy to cut and shape/form similar to a thin sheet of metal, but is incredibly strong. Works perfectly.
