Some customers can be open of the use of products to clean with, sometimes they are not.  Most of the times that I personally have done house cleaning there usually was not a preference.  This allows opportunity to disinfect after cleaning where there previously might not have been and reducing the spread of illness and disease.

Fortunately, there are a variety of professional grade and commercial products.  Most commercial products are readily available to consumers and most people are usually familiar with these products.  Lysol products are probably the most known for their ability to disinfect many surfaces.  Zep is offering disinfectants as well.  Bleach is also commonly known.  I would caution individuals, as I have seen people use bleach and get it unintentionally on the bottom of their shoes while cleaning and disinfecting bathrooms, then accidentally got bleach on carpets.  However, bleach will disinfect and they can give a solution for making general disinfectant with the amounts you need with contact time at: www.clorox.com.  

There are also more products becoming available to consumers and business owners than regular grade commercial products.  Most indications of people not liking disinfectants in their homes there usually is a level of sensitivity either towards the product or smell.  Working either residential or commercial cleaning can allow you the opportunity to implement disinfectants for those individuals and businesses.

Obviously, were businesses are concerned especially with public access, the more we can help prevent the spread of disease and illness with active participation in disinfecting those environments greatly improves the overall health of those individuals.  Look for services where disinfecting is part of the cleaning process, ijcsa.org can be a great resource to check your area https://www.ijcsa.org/Janitorial-Service-Directory-Find-A-Janitorial-Service-JanitorialServices.
