Re: refrigerate apple cider vinegar?
are you using the organic kind?
when i used it, i never refrigerated it. i just kept the bottle in the cabinet under my bathroom sink. i dont think there would be any harm in refrigerating it, though. using cold apple cider vinegar on your face in the morning will surely wake you up!
i never washed it off either. i would put it on, wait for it to dry, then just went to bed.
