Odors returned within 24hrs
Product arrived in a timely fashion. I used it in a 2-story 16ft x 24ft storage building that the previous owners used as an office and kept a cat inside. I had pulled all the carpets/padding out and removed the paneling but even though there was no urine stains in the subfloor, there was still pet odors present. I used the product as directed, one upstairs and one downstairs. I had the air conditioner turned off so it would not remove any of the gas. 24hrs later, I went in and could smell the chlorine and opened the windows, turned on the AC to air out the space as directed. I was very hopeful this product would have removed the odors from the space but within a day, the odors returned. I feel I used the product as directed but open to suggestions if I needed to do something different.
