What is wrap foil around doorknobs?

Wrapping foil around doorknobs may help prevent the spread of germs, especially during cold and flu season. The foil acts as a barrier between the user's hands and the potentially germy surface of the doorknob.

Additionally, some people use foil to prevent paint or stain from getting on doorknobs during home renovation projects. The foil can be easily removed once the project is complete.

It is important to note that while wrapping foil around doorknobs may reduce the spread of germs, it is still important to regularly sanitize high-touch surfaces to keep them clean and free of harmful bacteria and viruses.
