Why is it important to clean the environment?
Microorganisms (bacteria, fungi, viruses) are present throughout our environment and can cause infection. The environment can serve as a breeding ground for these organisms. Cleaning and disinfecting housekeeping surfaces and medical equipment, especially those that are frequently touched, is important to decrease and/ or prevent the spread of these organisms to people particularly if they are rapid acting pathogens.  Human fungal infections may fail to respond to contemporary antifungal therapies in vivo despite in vitro fungal isolate drug susceptibility. Such a discrepancy between in vitro antimicrobial susceptibility and in vivo treatment outcomes is partially explained by microbes adopting a drug-resistant biofilm mode of growth during infection. High efficacy methods of high temperature steam may be one of the few solutions for surfaces infested with biofilms.

What should I worry about when doing such cleaning?  Cleaning is important.  Having a regiment is important.   Preventing the spread of toxic chemicals is important.  If you are a restaurant, rental car agency or any other commercial business it is also important to know the speed of removal and the frequency of the regiment.  High temperature steam is one of the fastest methods.
