Hello! I’m sorry to hear that your product stopped spraying when the bottle was half empty. I understand how frustrating this can be. Here are a few points to consider that may help:<br /><br />1. Clogging: The nozzle may be clogged. You can try running warm water over the nozzle or soaking it in warm water for a few minutes to loosen any clogs that may have occurred.<br />2. Aerosol Mechanics: The product in the Air Mist can is an aerosol that is sprayed out by nitrogen, a natural propellant found in the atmosphere. Unfortunately, once the nitrogen has been emptied from the can, the aerosol spray will not work, and any remaining product will stay in the can.<br />3. Proper Positioning: As directed on the pack, the product should be sprayed with the can in an upright position. If the can is tilted upward or downward when spraying, it may release excess nitrogen, reducing the amount available to use the full contents of the product.<br /><br />We would love to help you further.
