California Scents Odor Eliminator Air Freshener (Coronado Cherry Scent, 1 Pack)

I purchased several containers of this cherry air freshener because itsmells great to me. It's advertised as an odor eliminator. I had a problem with a heavy, unwanted odor in one of my upstairs rooms. One container didn't take care of the odor. Two containers didn't take care of the odor, but I could tell it was trying. SO, I added a 3rd container and removed all three lids. The next time I visited that room, the smell was gone. By that time, the first container (gel) was amost empty. I have not added a replacement container. The smell is still gone. The odor was caused by food trash in a can that contained food was not removed for a few weeks. After the odor is gone, I put the black lid back on the container. That lid helps the gel last longer.
