I just bought a Smooth Treadmill and put it in my sitting room. I don't know if I imagining it or what but I feel after three days the room already smells like a gym. I've worked out only twice in there. If you have a treadmill or other exercise machine in your home, what do you use to clean it and do you spray the room with anything special? I hope this is my imagination, I would hate for people to come to my home and smell weird smells. Please advise.
