What is aluminum foil on door knobs?

Aluminum foil is a thin metal sheet made of aluminum that has several applications, including cooking, packaging, and insulation. One of the lesser-known uses of aluminum foil is for covering door knobs, which is a technique some people use for hygiene purposes.

Door knobs are commonly touched by multiple people throughout the day, making them a hotbed for bacteria and viruses. By covering them with aluminum foil, the foil can act as a barrier between the hands and the knob, reducing the spread of germs.

However, it's worth noting that this technique can only offer temporary relief as the foil can wear and tear over time. Additionally, using disinfectants and washing hands properly are more effective ways of preventing the spread of bacteria and viruses.

Overall, while there may be some benefits to using aluminum foil on door knobs, it's essential to prioritize practicing good hygiene habits to stay healthy and prevent infection.
