This is the best product I’ve ever used for pet stains. Believe me when I tell you I have literally used every pet stain product out there. I originally purchased this for some older stains that I had. I was intrigued buy the use of micellar in the ingredients as it’s something with which I’m familiar and use as and efficient make up remover. Wow! Pristine Pet got out stains in my carpets that were two years old! Color me amazed! I was inches away from replacing an entire room of carpet to be rid of those stains. I used this product as my final attempt at removing those stains and was pleasantly surprised at the results. Thank you Pristine Pet!
