Saw this at an estate sale by the kitchen sink. It looks like a bar of soap but it’s made of solid metal and has no smell.

The act of rubbing allows the sulfur molecules in the odors to bind with the stainless steel, effectively removing the smell from your skin. While it might seem counterintuitive, this method is a time-tested solution for cooks and chefs who frequently deal with odoriferous ingredients.

The effectiveness of stainless steel odor remover bars lies in the chemistry between the metal and sulfur compounds. Many strong kitchen odors are caused by sulfur, which is found in garlic, onions, and fish. When these sulfur molecules come into contact with stainless steel, they undergo a process called adsorption.

Adsorption involves the sulfur molecules binding to the surface of the metal, which effectively neutralizes the odor. This interaction is facilitated by the smooth, non-porous surface of the stainless steel, which allows for maximum contact and efficient odor removal.

Stainless steel odor remover bars are particularly effective against the potent odors of garlic, onions, and fish—common ingredients in many cuisines that can leave lasting smells on your skin.
