[and a bit of brand-naming consumerism]
Some things that are working for me at the moment:
Smoked Sea Salt. On everything.
I am still in love with my Kenmore Calypso washer & dryer. High Efficiency, large loads, cost a fortune ten years ago (like maybe $1400?) but still going strong. I can do a month's laundry in four loads: lights, darks, sheets/towels, and delicates on the "ultra handwash" setting. Love. It.
Washing my hair with baking soda. My hair is cleaner, stays clean longer, it's cheap, easy, no plastic bottles or weird chemicals going into the landfill/water stream.
Started using vinegar as fabric softener. The vinegar smell is gone by the time everything leaves the dryer. Works to soften towels and get grease out. Cheap and genius, and really just as easy as using the other smelly stuff.
