LOL, I have washed cloth diapers for NINE years and counting, as the youngest is still not out of diapers, and it does appear that
I'm miraculously 9 weeks pregnant again, after four miscarriages and some weird hormonal issues that made the doctors and my midwife say I would never have another baby, so if this one makes it, I have at least 2 more years of cloth diapers. I haven't used paper diapers in, well, ever. The washer will be fine
You can run a bleach wash cycle afterwards if you want; add 1c bleach to the washer, no clothing, and run a hot water cycle, unless your septic system doesn't like bleach.
I use paper towels in the bottom of the incubator, the only thing I use paper towels for. [We use washable kitchen towels, cloth diaper wipes, reuseable everything, just about. It has saved us a fortune, even accounting for water, electricity and detergent.] I like the paper towels because if the humidity needs help, I can spray water in via the air holes and help spread it over a bigger surface area to bump humidity.
I have also some canning jars with sponges in them inside the incubator that I use to increase humidity. I do find I have to add water quite often, and I can't figure out why, as the humidity in the house runs 45%. But the bator, without help, wants to hover at way less. Very odd.
