Hey Mike, thanks for answering all these question I can't tell you how much this forum has helped. So the title says it all. A customer spilled milk, fish, and lobster meat in a car in december 2015. The smell is baked in to the carpet by now. They are paying me to get rid of the stench (it's awful). I shampooed the spot for about 3 hours using a bisell portable shampooer, foaming carpet/upholstery cleaner, and used a full bottle of Meguires odor elminator in it. The smell is obviously still there but about 75% of what it was. I suggested they do the same thing every week for about 2 months. Any suggestions on what else to do?? Thanks again.
