Amco Rub-a-way Bar Odour Eliminator
It is claimed that you can remove the smell of garlic, or onion, or any other sulfurous vegetables from your hands by rubbing your wet hands with stainless steel. Some folks say this works wonders, some say it does nothing.
This reaction has to do with the organic sulfur compounds released when you cut into alliums like garlic. Our noses are very sensitive to these compounds. We may appreciate the the slight garlic aroma coming from a big pot of past sauce but we cannot stand to have that smell on your hands. Metal ions are supposed to have a high affinity for sulfur and nitrogen compounds. Thus, these stinky compounds react with the stainless steel, either removing them or rendering them less stinky.
