What is wrap foil on doorknobs?

Wrap foil on doorknobs is a simple and cost-effective way to reduce the spread of germs in public places. The aluminum foil acts as a barrier between the user's hands and the doorknob, preventing direct contact and reducing the risk of transmitting germs and viruses. This method is often used in hospitals, public restrooms, and other high-traffic areas where the spread of germs is a concern. To wrap a doorknob with aluminum foil, simply tear off a piece of foil and mold it around the knob, ensuring the entire surface is covered. The foil can be easily replaced as needed for a fresh and clean surface.
