Ultra Odor Gone Spray is an amazing complement to the Semi Solid product. When air born odors occur, the Ultra Odor Gone Spray can be used to neutralize odors immediately! This product is not for long standing embedded odors, but for transient odors. This product works well when a person has just smoked in your home, after you've had fast food in your car, in the kitchen after cooking with strong spices, in the bathroom, and in many other instances. Ultra Odor Gone Spray will also remove skunk odor. This product is sold in 16oz non-aerosol spray bottles.
