Sheen Genie was made to be as odorless as possible has no foul-smelling odor to it. In fact, there is barely even any odor to it. In an effort to keep it clean, you’ll find that it’s a very neutral smelling formula. Some of the ladies have described it as smelling very clay-like or earthy. One description was that it smelled the same as her clay mask she uses to refresh her skin on her face. In other words you don’t have to wear a gas mask or even do this outdoors to neutralize a stench. It’s safe for your car and safe for the home.
