Mycoplasma urealyticum is a kind of mycoplasma, which has poor resistance to the external environment and is sensitive to ultraviolet light, drying, and heating, and can also be inactivated by fat solvents as well as commonly used disinfectants. Those who are positive for Mycoplasma urealyticum can disinfect their underpants by steaming them or by using commonly used disinfectants such as alcohol and other disinfectants of their own choosing. When washing the underwear, a large amount of water can play a diluting role and cause a decrease in osmotic pressure, inactivating Mycoplasma hyopneumoniae. Ultraviolet light, temperature, and drying during air-drying can also inactivate Mycoplasma hyopneumoniae, so the process of washing and air-drying underwear contaminated with Mycoplasma hyopneumoniae basically eliminates Mycoplasma hyopneumoniae’s infectious properties. When positive for Mycoplasma Urealyticum, you can use steaming to sterilize the underwear after washing, usually boiling for more than 30 minutes to achieve the sterilization effect. When it is not convenient to steam, you can also use chemical disinfectant to disinfect after washing, such as using 84 disinfectant soaking for more than 30 minutes, or using alcohol soaking for several minutes, can achieve the disinfection effect, after disinfection, remember to clean the disinfectant before wearing.
