Im sure you can guess from the title what my problem is. So far regular carpet shampoo from a spray can has proved worthless so it's on to some more serious steps. I'm going to get a blacklight bulb from Home Depot to locate the source of the smell and a big bottle of Nature's Miracle cleaner since it gets pretty good online reviews. Any other advice? The only good thing is that I can live with a cleaning product that discolors carpet. The smelly spot is under my bed so I don't care how it looks. I just want to get rid of the damned smell.
