Bleach Hydrogen Peroxide Kill Mold
On the Killing Effect of Bleach and Hydrogen Peroxide on Mold
Shi Youasked Yu: "Bleach and hydrogen peroxide, can kill mold?" Yu said: "This matter needs to be investigated in detail."
The main component of bleach contains chlorine and is highly oxidizing. In ordinary environments, chlorine and water phase together to produce hypochlorous acid. Hypochlorous acid is extremely active and can penetrate the cell wall of mold, break its cell membrane, and then destroy its internal structure, such as proteins and nucleic acids, so that the vitality of mold is cut off. However, if the mold is deeply hidden in porous materials, such as wood and gypsum board, the chlorine of the bleach can only reach the surface, and it is difficult to go deep into the pores to eradicate. If the mold is killed on the vertical surface, the deep ones can still recur.
And hydrogen peroxide is also a strong oxidant. When it encounters mold, it decomposes and releases new oxygen. This oxygen is very active and can oxidize the cellular components of mold, such as lipids, proteins, etc., causing damage to its structure and function, and the mold dies. And the products of hydrogen peroxide decomposition are water and oxygen, without residual pollution, which is beneficial to the environment. However, its stability is poor and it is easy to decompose. If it is not stored properly, its effectiveness will decrease rapidly, and it may be difficult to achieve the expected killing effect when applied to mold.
In summary, both bleach and hydrogen peroxide have the ability to kill mold, but each has its own advantages and disadvantages. When using bleach, consider the suitability of the material to avoid the shortness of the root that is difficult to remove from the porous material; when using hydrogen peroxide, it is necessary to ensure its effectiveness and use it according to the time and quantity. In this way, both can be used well to effectively remove mildew.
