Hello I bought some e liquid and hated the bottle and dropper it came in, so i washed an empty unicorn 120ml bottle to transferred it over to that, i shook out the water residue before but i didn't manage to get it totally dry, and well poured the liguid over to it, can that water residue cause any problems ? Spoilage or and dangers with health? Cuz i usually have a few flavors i switch so that particupar batch would remain in that for over a month.
