I have it bookmarked. I have saved so many shirts this way. And don't neglect the vinegar...it does wonders. If anything, the concentrated Oxy step can be omitted unless the stain is serious.
This.I use a garment bag in the wash and wash the socks on cold, delicate cycle, and then line-dry them. Works like a charm. I hand-washed them when I started but the time commitment was a bit much for socks. The garment bag prevents pulling.
