My laundry process is the opposite of a lifehack - I am incredibly fussy about hand-washing all my animal fibers and about a third of my underwear, make absurd use of mesh wash bags in the machine, own six different kinds of detergent... I mildly enjoy doing laundry, and would love it more if the dryer were in the apartment instead of in the basement.

I do not separate colors very often. Instead I use those color catcher sheets. (I don't generate large enough loads fast enough to color-sort, and my roomie and I don't share clothes-laundry tasks because our detergent/fabric softener preferences are opposite.) I have one lint-prone, bleed-prone fuzzy bathrobe that gets washed and dried independently.

I own a LaundryPod (like a giant salad spinner with a drain hose) for the large amount of hand-washing I do. It's a goofy device, but having a special thing that only handles my clothes saves me from having to scrub the sink (which usually has a little bit of purple hair dye lurking somewhere).
