First of all, it needs to be explained that stainless steel soap cannot be used as ordinary soap. It can neither disinfect nor decontaminate. Its only function is to remove odors, such as fishy smell, garlic smell, body odor, etc., so buy stainless steel soap , we must first see its use clearly. We know that the general traditional deodorization method is coverage, which is to cover the odor with fragrance, but this cannot really eliminate the odor, and it may produce more unpleasant odors after mixing (such as Liushen toilet water + sweat odor...); another way of deodorization is adsorption, but the adsorption deodorant will reach saturation after a period of use and can no longer exert its effect. The deodorizing principle of stainless steel soap is decomposing. When stainless steel is in contact with air and water molecules at the same time, iron ions will decompose the molecular structure that produces peculiar smell and "restore" it to an odorless state.

One point of view is that it may be that after the iron or chromium in the stainless steel contacts the odor molecules, the latter forms oxides, which are then taken away by flowing water. The idea is that you can achieve the same effect as stainless steel soap by using an ordinary stainless steel object. According to the effect test of a company's patented product by a German government agency, it is believed that because the odor molecules generally contain sulfur and ammonia compounds, the stainless steel material acts as a catalyst to convert them into oxides and then be taken away by water, which can eliminate odors. The effect of the smell, but how it works is not described.

In general, it is generally believed that the deodorization principle of stainless steel soap is decomposed: when the stainless steel alloy contacts with air and water molecules at the same time, it will produce a catalytic effect, decompose the molecular structure of the odor, and "reduce" it into an odorless state. The specially polished frosted surface of stainless steel rubs against objects, and the released iron ions combine with odor molecules to achieve the effect of eliminating odor.

During use, stainless steel soap is usually "half put into water and half exposed to air". When using it for the first time, it will work normally after 5-6 hours of waiting. It is worth mentioning that the effective use time of ordinary stainless steel soap can last for 3 to 5 years. This lifespan is much longer than ordinary soap, and the price/performance ratio is relatively high, but the effect of use varies from person to person.
