I just received my Odorcide starter pack and it saved the day. We had a vacation home turnover and the previous guest vomited on the carpet and tried to clean it up only pushing it further into the pad. I applied disinfectant and HWE'd the room. It still smelled horrible. I tried an odor counteractant and it just masked the smell, so I applied Odorcide and it did the trick. I'll definitely be stocking this full-time.
