I want to thank all of you who have weighed in over the past few months on Fast Acting Enzyme, “how to” and “benefits of”. After reading all of the threads, I recently have encountered two tough jobs where by using the FAE I cut down on time and effort to complete. This stuff really works and works very well. I had one lady, who owned a rental home, who came back after our cleaning and only half jokingly asked if we had replaced the carpet. Good stuff, keep it coming!
