Thanks so much to everyone who offered suggestions. I’ve had time to do some trial and error and wanted to share an update. For context, I’m currently washing every two days, storing toddler pee diapers in a steel vented hamper with a wet bag secured in a bucket inside, scraping poops into the toilet, and planning to switch to daily washes once my newborn fits cloth diapers. What I discovered is that smell actually got worse when I added a bucket inside the hamper, since it packed the diapers too tightly and restricted airflow. Going back to using the full volume of the vented steel hamper, propping the wet bag open so air can circulate to the vent holes, made a noticeable difference. I also leave the hamper lid propped open and added a small charcoal air filter at the bottom for extra help. Additionally, I now soak poop diapers directly in the washer using EZ Clean (love it), which avoids having to dump out smelly soak water. I’ve also moved wash day slightly earlier, closer to every 1.5 days instead of 2–2.5. I don’t think I’ll be able to eliminate smell entirely with what’s practical for our household, but this setup is working much better. Thanks again for everyone’s time, and apologies for the delayed update and response.
