Water alone does not necessarily kill germs, but it can help to remove them from surfaces or dilute their concentration. However, hot water can kill some germs by denaturing their proteins and disrupting their cell membranes. Additionally, water combined with soap or detergent can help to break down the outer layer of germs, making them easier to remove. Water can also be used to wash away germs and dirt, reducing their presence on surfaces. Ultimately, the effectiveness of water in killing germs depends on various factors such as temperature, duration of contact, and the type of germ being targeted.
