i was thinking maybe baking soda in my rinse to soak up or neutralize any toxins. i think the h2o2 is a great idea as well, as long as it was a quick rinse. rancid oil is oxidized oil, and rancid is not good, thats for sure. i will post a follow up on anything i try. they are sitting in a ziploc in the fridge and they are not tempting me at all. tells ya how bad they are!
