Im currently washing our diapers in ALL no fabric softener, no bleach, no dryer sheets or nothing. I usually let them air dry...

But my friend said the other day she used to use baking soda and tea tree oil to wash hers?
Should i be doing this too??

You can add both to your wash if you like. Baking soda will help to whiten/reduce stains and odors, and TTO will help to freshen and kill germs.

OH Thank you very much.. I think ill try that!
