We started making our own laundry detergent. Big win on price vs fiat “pods” that attempt to fix manufacturer profit per load regardless of size, and overpriced fiat boxes of who knows what. Lots of recipes online with epsom salt, optional borax, washing soda, baking soda, ground soap, optional essential oils. Likely halved our cost per load.

Yeah, it's amazing how much laundry you can get done at a tiny fraction of the cost. And after making my own soap, I've even stopped using my dishwasher and just dissolving grated soap in water and hand washing everything.
After trying a couple laundry mixes, I'm just down to a half cup each of washing soda and oxygen bleach per load and it works great. Borax if I'm washing my shower curtain for the mold.
