Hi Maryjane. Borax will not bleach your darks. It is perfectly safe. ;) When I was making my own with borax and baking soda, I did my dark in it all the time and no problems!!:) Hugs

Thank you so much farmgirls! I am teaching a class in my home for 40+ sisters from my church on how to make laundry detergent and I know they will ask this question! I have been using my detergent for 2 months now and have not seen a change in my darks but needed to know from you pros! Isn't homemade laundry detergent the best!!! xox
