Please read all CAUTION:, DIRECTIONS:, and WARNING: labels on all products before use. Below is an excerpt from the INSTA-SCENT ULTRA label.
There is always the possibility that liquid air fresheners can stain or damage if they are not applied properly. You can greatly reduce this chance by carefully spraying any and all brands of air fresheners UNDER THE FRONT SEAT INTO THE CARPETING. DO NOT spray liquid air fresheners on any visible carpet area, floor mats, dashboard area, doors, seats or headliners. Permanent damage or staining can occur.
Pour entire contents of one to two bottles (depending on the level of fragrance strength desired) into a clean one gallon container. Place hose in bottom of gallon container and fill slowly with fresh water. Screw cap on gallon container and shake well until dissolved. Apply 8 to 12 sprays of the finished product into the carpet area under the front seat using an all-purpose spray bottle.
