Stainless steel soap is a piece of stainless steel, in the form of a soap bar or other hand-held shape. Its purported purpose is to neutralize or reduce strong odors such as those from handling garlic, onion, durian, guava, salami, or fish.[1]
No published scientific studies are known to have been conducted on the efficacy of these soaps, for which serious doubts have been raised.[2][3]
