Well I just made my first kiwi mop today and I have lost more ink from it trying to open it when its full and squeezing to much out then actually bombing. Its a little under halfway right now and its easy to open now and works great. Like I got the instant wax shine bottle and i can feel the ink is about right under the text on the bottle that says "instant wax shine". I am sure all the bottles have the text in the same place so just fill it up there.
