I would think that vinegar and salt would do the trick -- no other chemicals should be required. Unless, of course, your hot sauce has lots of other "stuff" in it to raise the pH to an unsafe level -- fruit, sugars, etc. My guess is that your utensils and storage contaners were not _pristinely_ clean when you started. Good luck. Matt --- Vancouver Pepperman <vanpepperman@shaw.ca> wrote: > Hi all, > > What's a good preservative to use in hot sauces?
