Not in to all natural, but this works great. Best I have tried.
I tried the spray with the best reviews I could find and tried on my old carpet stain (dog urine). It works, but the stain keeps coming back. It will be clean beige for a day or so but then slowly turns gold again. For awhile I thought it was my eyes, but my mother could see it too. Anyway, I did some research online about cleaners and found this one. I have used the septic treatments with “good” bacteria, so I knew that they eat the gunk in the septic system. Seemed to make sense they might eat the pet waste in a stain. According to other reviews this product works better because the bacteria keeps eating until nothing is left, then dies. Well, it works. No more stain residue. Now you have to apply liberally. make sure it soaks through the stain,, but then look out. It took several days to be gone completely, but it was. I am totally sold, Some of the other products “clean” what is on the surface, but in the process of “lifting” the stain out on carpet, then just bring the stain back to the surface. This worked from the top down. Excellent product, I think its the best!
