Excellent question - I've been wondering myself. I'm interested in trying soap bars, but the ACV rinse kind of turns me off, although not for the same reasons. Honestly, it just seems like a hassle and I'm lazy!
hmkenny could be right, and you could try a weaker solution. It might help with the odor issue, too. I also use white vinegar (always have it around), and I find the smell to be slightly less obnoxious. However, having very sensitive skin myself, I know that if you're sensitive, you just are. And if the smell is a deal-breaker, I can relate.
curlyserf, do you know the dilution ratio for a citric acid rinse? Just curious.
Just had a brainstorm: we should ask kathymack if there are other options - she knows everything! Calling kathymack, calling kathymack....
