|Left is control with just water, Purex 2, Bleach, borax|
The stats before:
2" of elastic, (fully stretched to 6 inches.)
1 piece of white PUL
1 piece of pink PUL
50/50 water to bleach, Purex 2, and Clorox in their own container
|6 hours later|
6 hours later:
2" of elastic which could stretch to 6 inches still
same size White and Pink PUL with no runs or staining an all the swatches.
This ratio was a 50/50 mix of the diaper killer for 6 (six) HOUR soaking period. Because they survived and would still be able to be used; I doubt a 3/4 a cup if bleach in a 40 gallon drum (or 640 cups) will ruin your diapers. Washing once a month with bleach will NOT kill your diapers. Using borax or Clorox 2 (or Purex 2) as an occasional additive will also NOT kill your diapers. Obviously if you have a cotton print and you use regular bleach, that will fade your print. But that is what color safe bleach is for. :)
Here is a pretty good blog about borax if you are worried about health safety. I will get around to doing a washing test with borax.
