Steel soap
Steel soap (also stainless steel soap ) is a handy piece of stainless steel with a fine to micro-structured surface. It is said to have a distinct odor- reducing effect when rolling or rubbing with water on skin contaminated with certain odorous substances, which cannot be achieved with ordinary soap , for example on the smell of garlic, onion, cabbage, fish and gasoline.
In scientific evaluations, doubts about such effectiveness are sometimes expressed, and sometimes attempts are made to explain the effect proven by experience reports and unconfirmed empirical tests. A catalytic effect is assumed for the steel soap . This means that the stainless steel temporarily combines with the odor-causing substances on the hands and thus enables them to be oxidized into water-soluble and non-gaseous substances. An alternative explanation is the adsorption of the odor molecules on stainless steel.
