Follow up. How much soap do you use? I have powder Tide Free and some Country Save that got good reviews for diapers. I think I heard something about using less soap?
Diapers are your dirties laundry you will do. Do a quick rinse. Then a heavy duty cycle. Use real laundry detergent (tide/gain/etc). Use the free/clear versions if you have skin issues. I also like to throw in an extra rinse.
Unless you live on a dairy farm. Diapers for the most part have nothing on those jeans and coveralls.
