A fresh onion should smell garlic-like and pungent with a grassy smell and a subtle hint of caramelization odor. Once it has gone bad, it will start to smell like rotten garbage or rotting compost. Note: Take note that these signs apply to all types of onions: whether it's white, red, or yellow onions.I think Muley Freak solves that problem with Klean Freak wipes. They are supposed to leave you smelling “freakishly fresh.” If you would get to the point of smelling like old broccoli, I don’t know if they would help.
I have never tried them myself.
