Stainless steel soap
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.
Companies that produce stainless steel soaps claim that the odors these foods cause result from sulfur, which turns into sulfuric acid upon washing the hands. The aim of the stainless steel soap is to then bind to the sulfur molecules, thus removing them and the associated smell from the hands. However, scientific evidence of the efficacy of these soaps appears lacking.
