We are FINALLY stink free (of course I have given up all hemp too, don't know if I have the bravery to try hemp again), this is after I was ready to go out and buy a top loader.
Here is what I do (my stash is now FBs and microfiber inserts)...
-Most poops will plop off into the toilet, if it's a gross sticky poop, we minishower it, and then wring out and stick in the dry pail
-I also sprinkle BS in the diaper pail a few times a day and wash every other day, but thinking about maybe going to every 3rd day, since I have a good stash now.
-I have an older model frigidaire gallery front loader and we have a water softener, our water heater is set at about 125 F, I WISH we had a washer that could heat up water on its own. I used to be a nurse on the burn unit, so I am too weary of pouring extra boiling water into the washer or turning up our water temp super high for safety reasons. I had waaaay too many patients who spilled boiling water on themselves by accident at home, and I'm afraid that with a toddler underfoot, it might be even worse and I'd spill it on him by accident.
-Cold prewash with a generous squirt of Joy liquid dish detergent (currently using the citrus scent antibacterial scent, normally I'm not for antibac products... but since poo is involved, I'm ok with it.).
-Hot/cold cycle (extra rinse) with nothing extra (there's enough joy left from the prewash)
-1/2 teaspoon of sportswash and another hot/cold cycle (extra rinse), sometimes I add vinegar, sometimes not... I don't think it makes a difference to be honest.
-Sometimes I will do another cycle w/o anything else, but I think I'm being overly anal, and last time I did dipes, I dropped this extra cycle and everything seemed to be fine, which is great... less work, energy, water and $ involved.
When I was using HE or any kind of other laundry detergent it seemed like no matter how little I used, I would have to do a ton of extra cycles to get rid of suds, but still had stink issues. I was ready to pull my hair out. I believe this is d/t my front loader/soft water combo... it made things EXTRA frustrating. The liquid dish detergent seems to be the key to solving my problems, it appears to rinse out more easily. I don't know if I *really* need the sportswash cycle or not, but it makes me feel better, lol. My dipes now come out smelling faintly citrusy and kind of neutral smelling... in my book, PERFECT!
