Warning. This is an awkward post. It's deep winter and many of us are trapped indoors without the flow of fresh air from open windows. I, personally, have become quite conscious lately of daily smelly moments both at home with guests and at work (the elevator is the worst) where I've been trapped by someone passing gas or simply wished the bathroom at home would air out quicker. I myself will plead guilty on occasion. That said, there is one really effective way to erase this smell immediately. Do you know it? I have found that many people do not.
