I had the issue of a small spot spreading and turning into a larger one due to several cleaning attempts. I tried nature's miracle at first but it didn't remove the smell. I then tried a carpet shampooer and, while it helped some, I still have a slight odor coming off the carpet. I even tried using the hand tools and scrubbing it out. While the room itself doesn't smell that bad (well, we have the windows open), I want to be able to get this smell out. The rug also feels like it still has that "sticky" feeling to it a little.
Since it is larger than what it was, is there something I can use with my carpet shampooer to help? Is there a special process? Thanks.
