How can you keep your hands away from fishy smell using metal soap, the “odor killer” in the kitchen?

In daily life, we always encounter some unpleasant odors, such as the strong smell left on hands after handling garlic or fish, which is often difficult to wash off with water or ordinary soap. Surprisingly, there is a special "metal soap" that can quickly remove these stubborn odors.
Metallic soaps are mostly made of stainless steel or other metals. They look like regular soaps, but their working principle and weight are different. The magic of metallic soaps lies in their metal components, especially the iron and chromium in stainless steel. Metallic soaps may look ordinary, but the science behind them is very interesting. Now, let's learn how metallic soaps become the odor-killer in the kitchen.

1. The chemical secrets of metallic soaps: the credit of catalytic reactions

Metal soaps are usually made of stainless steel. These odors mainly come from some sulfur compounds and amine molecules, such as those in onions, garlic, and fish, which easily adhere to the skin. When metal soaps come into contact with water, the oxide film formed on their surface will produce a catalytic oxidation reaction, thereby converting these molecules into odorless or low-odor compounds. This oxidation effect decomposes the odor molecules, thereby reducing the odor on your hands.

2. The magic of physical adsorption

In addition to chemical reactions, metal soap can also remove some odor molecules through physical adsorption. We know that there is a layer of microporous structure on the surface of stainless steel, which can absorb small odor molecules. When we rinse our hands with clean water, these adsorbed odor molecules are also taken away. Under the dual effects of this physical adsorption and chemical reaction, the deodorizing effect of metal soap is particularly effective.

3. How to use metallic soap correctly, such as:

Wet Soap: Wet the metal soap before use so that its surface is in contact with water to promote chemical reaction.

Rub thoroughly: Rub the metal soap on your hands for at least 30 seconds to allow the metal surface to fully contact the skin, thereby better absorbing and transforming odor molecules.

Rinse thoroughly: Use clean water to thoroughly wash away the odor molecules on your hands to achieve the best odor removal effect.

4. Environmental protection expert

In addition to effectively removing odors, metal soap has high environmental value. It does not require the addition of chemical detergents and can be reused many times, reducing dependence on disposable plastic bottles of soap and detergents. This simple and efficient deodorizing tool brings convenience to our daily lives while reducing the impact on the environment.

5. Support for scientific research

Many studies have provided scientific evidence for the deodorizing effect of metallic soaps. For example:

①Sulfide molecules are easily adsorbed onto metal surfaces (especially stainless steel surfaces) and undergo chemical transformation in a short period of time.

②Electrochemical effect: redox reaction, "micro-electrochemical reaction" of metal soap. That is, when water comes into contact with stainless steel, a tiny electrochemical reaction will generate micro-current on the surface of stainless steel. These micro-currents will promote redox reaction, further degrade or transform odor molecules such as sulfide and amino, thereby eliminating odor.

The weak electric field generated by the friction of stainless steel in water has been confirmed by many studies. These electric fields can effectively remove surface odor molecules and inhibit odor. Studies have also shown that stainless steel will form a weak electrochemical environment in water, thereby promoting the oxidation and decomposition of odor molecules, etc. These all highlight the uniqueness of metal soap, so that we can understand its use principle while enjoying the refreshing experience it brings with peace of mind.

Metal soap may seem ordinary, but it has complex chemical and physical mechanisms behind it. It not only performs well in removing odors, but also has advantages such as environmental protection, which makes it a "deodorizing artifact" in kitchen life. Next time, when we are troubled by odors, we might as well try this cheap and simple "black technology" to feel the comfort and convenience that science brings to life.
