I used a case of it a year ago. Good on light carpets. Does a good job of deodorizing. Has a strong orange scent. Doesn't pass the dish test for encapsulation crystallization- dries sticky in the dish.
Does a very good job for doggie urine, etc. Not sure re. cat, but might work if deposits were hit with something else first followed by dwell time, then Hydroxi.
I don't see it as an "everyday" solution for your chems, but for light carpets or pet issues, not a bad selection. The similar product H2Orange2 (Carpet Complete) is Green Seal certified btw, but is expensive.
i have heard that "encap" products that have dlimonene in them will not work and will resoil the carpet! i wouldn't use them. i did try the above said product with less than average results.
