My dear darling cat has a fetish with glasses sitting about, particularly if they have a liquid in them. Well as my luck might have it, about a week ago he knocked my remaining glass of milk over and it spilled onto my carpeting. I cleaned it up quickly with many paper towels but neglected to pull my couch forward to realize that it had spread along the base board. A few days later I discovered a less than pleasant aroma and I've nailed it to souring milk in the fiber and presumably padding of my carpet. I've tried doosing it with water (a second glass knocked over by the resident feline a few days later and scrubbing it with pet odor Resolve. But it hasn't fully disipated yet. I'm trying to avoid having the carpet cleaned professionally, especially before the holidays... any suggestions?
