This stainless steel soap is made of 304 high quality stainless steel, used to wash hands to remove odor. For example, after processing onions, garlic, green onions, fish and other foods, remove unwanted odors from the hands and restore the original taste. The deodorization principle of stainless steel soap is basically decomposed. When the stainless steel alloy is in contact with both air and water molecules, catalysis occurs and the molecular structure of the odor is decomposed and "reduced" into an odorless state. The stainless steel material rubs against the object through a specially polished frosted surface, and the released iron ions combine with the odor molecules to achieve a convergence effect. Stainless steel soap is usually "half immersed in water and half exposed to the air". When you use it for the first time, it takes 5 hours - 6 hours waiting for normal work. Effective use can last for 3 to 5 years. .
