[diach]

I am not domestic, and I need help. Last week Murphy got sick on my couch. I cleaned it up right away with upholstery cleaner. The next day there was a sour smell. Since then I have cleaned the couch twice with the attachment on my rug shampooer. I also sprayed Fabreze a few times. My couch still has a sour smell. It is a recliner couch so I cannot remove the cushion. At the time Murphy was eating Nature's Variety-beef. Since then I have switched back to Candidae. (That's another story!)
Any suggestions! Thanks in advance.
