My Mother kept a fresh bottle around the house, only opening it on "stinky" occasions. if you have forgotten them, they were a glass bottle containing a heavy "wick" hung on a wire frame, which drew up out of the bottle a few inches to dispense fragrance into the air. Haven't seen one in 50 years! Frank
Their products look a little different but Air Wick is still in business, still selling stinky stuff for the house.
