In general, boiling water for about 30 minutes can kill or inactivate some of the fungi and make them lose their pathogenicity. Fungi are eukaryotic organisms that are widely distributed in water, air and soil. It is usually not visible to the naked eye and is mainly characterized by mycelium and spores as the characteristic structure under the microscope. There are many different kinds of fungi, and the number of discovered species has reached tens of thousands, but only a small number of them are pathogenic. Most fungi do not tolerate high temperatures, boiling water for about 30 minutes to achieve the purpose of disinfection and sterilization, so that it is no longer pathogenic, even if the fungus again, will not be infected with the disease. However, not all fungi can be killed by high temperature, and timely treatment is needed if necessary. In addition, it should be noted that sunlight cannot make the fungus inactive. If some clothes cannot be ironed for a long time, it is recommended to choose medical disinfectants and other methods to kill the fungus.
