Most viruses and bacteria, including Corona virus can remain on a random surface (such as wood, metal, plastic, glass, etc…) up 9 days. Every day we are exposed to hundreds and thousands of bacteria and viruses at our homes.
When you clean your home or invite general cleaning services, they use spray and wipe the cleaning materials. This way of cleaning in most cases move bacteria and viruses from one surface to another since the rag is not cleaned well between one surface to another.
