Only related to body care, but can't figure out where else to post this. We've been using Seventh Generation unscented detergent for a long time, but have moved and it's much more expensive than at our old coop.I noticed wonder balls and green laundry balls on Gaiam. Has anyone tried them? You can use without any detergent (although I'm not sure I would do that with dipes). The green wash ball is a ceramic that changes the water pH to that of detergent. The wonderball is minerals and magnets.
