The GEHATI fragrance sprays are our most popular product because it works! Any unwanted odor--smoke, dog poo, human poo, baby poo, gym shoes, trash cans, mildew, spoiled food, etc.--a squirt or two instantly kills the smell and the scent from the spray lingers for 2-3 days. Not kidding, see for yourself! There are no dyes added and it's sensitive to people with bad allergies or sinuses.
