Worked fairly well as a temporary (day-ish) eliminator of pet odours in our carpet, which were pretty bad. Used in a room of about 100 square feet and only got four uses from this tiny bottle. The spray is wide, which is good for coverage, but makes it harder to breathe while using; a mask would fix that. It definitely stings the lungs and caused me cough for awhile afterward. So obviously keep all people and pets off and away until it's completely dry. There was no lingering scent, which was a bonus.
