Before use, twist and remove the outer cover to remove the inner cap. Place the outer cover back on and place the deodorizer in a designated spot, ideally in a central location.
Note: For external use only. Do not remove the filter paper inside the outer cover. Do not place in direct sunlight or head. Do not tip over as the liquid will seep out. The solution may become slightly cloudy and the filter paper may become discolored over time, however, this does not affect its performance. Discontinue use if you feel any discomfort. Follow additional instructions on the packaging.
