How do I open the spray bottle to refill it?
It's very similar to opening a medicine bottle. Hold the bottle with one hand, with the bottle sitting on a table. Put your other hand on top of the sprayer and push down and turn counterclockwise at the same time. You only need to turn it about a quarter to a half of a turn and it will pop off. Don’t worry. You will not break it. To put it back on, just push down and turn the sprayer clockwise to line it up.
