I ordered this stuff on a whim because it kept popping up in my fb feed and well we’ve been stuck at home and the carpets were driving me mad I foster with a local rescue so we’ve seen our fair share of accidents with 2 litters of puppies, multiple adult dogs needing a space to decompress and relax before finding their forever, and one foster fail. I thought I’d tried everything. But this stuff is amazing!!! I ordered the two 32 oz. spray bottles to test it out. Now, I wish I would’ve ordered more the first time and had taken more before and after pics...but I didn’t really think this stuff would work. This one was an old stained area after one treatment! One!!! I just ordered the gallon size so I can treat every inch of the carpet. I am thoroughly impressed! Thank you for such a great product!!!
