smell comes from decaying bacteria. so wash thoroughly before and after your ride. yes, before and after. also you might stay away from garlic and foods that contain garlic. my last employer had a shower so it was a commuters heaven. I showered before my ride, after I got there, and I also changed my clothes. don't think you can get by with some baby wipes or without chaning your clothes. cycling specific clothes are best cuz they rinse and dry quickly. trishorts are great under regular street clothes cuz they have a thin liner but once you get where you are going you're gonna want to take them off and let them air dry. my last employer also had a boiler room where I could air things out during the day. like I said, a commuters heaven.
