Thread: ok bac water question and sterile water q also

ok bac water question I have BAC water that expired in november 2011 and been in the fridge the whole time is it ok to use on peps still and sterile water question also I have new sterile water is that ok to use on peps and doesn't bac water work longer for pep's or no or is the sterile water fine to use

thats what I thought it's been in the fridge the whole time what is the one thats last longer acidic acid one? and can that only be mixed with certain peps right ?
