The liquid inside a new atomizer is called the "primer". It keeps the coil moist while in transport and storage. I do not suggest cleaning the atomizer with water or any other substances before or during use. You can roll up a paper towel or kleenex, insert it into the atomizer and blow gently through the battery connector end. This will clear out the excess primer fluid. You can also use this method between flavor changes. There is also the dry burn, hit the button on the battery (short burst) a few times to burn off the primer. Be really careful if you do this, you can burn out the coil and break your atomizer.
