New research has revealed that salt can be used as a safe and simple way to disinfect surfaces. Scientists at the University of Manchester have discovered that salt can be used to kill bacteria, fungi, and viruses, providing an effective and inexpensive way to reduce the risk of infection. The research team tested a variety of salts, including table salt, sea salt, and rock salt, and found that all of them were effective at killing the pathogens they tested. The researchers believe that the salt works by disrupting the cell membrane, which leads to cell death. Salt is also a natural disinfectant, meaning it is safe to use and unlikely to cause any harm.
