just bought a house whose previous occupants smoked extensively indoors. The cigarette smell clings to every surface, as does the nicotine. Spray any wall and it will run yellow with nicotine buildup. Anyways, I'm in the process of deep cleaning EVERYTHING and I wanted something that would hopefully control the stench long enough for me to clean the place out without succumbing to a stink-induced migraine. The spray is good for a limited amount of time. It's not a forever product; it's a temporary band-aid solution to control cigarette smell, and it does a decent job at it. I can spray a room thoroughly and have it smell lightly scented, a bit perfumey but not overpowering. The cigarette smell is mostly but not perfectly masked. It's enough to get in, clean, and get out. The next day when I'm back at it again, the cigarette smell is back to its original stinky strength, but another spray will control the smell again for another day of cleaning. Overall, decent product if you accept that it is not magically removing the smell from any room. Controls it for a set amount of time. Does not get rid of the need to do a deep clean of stinky areas. Packaging is great and eco-friendly. Good value.
