The length of time that your disinfectant remains wet on surfaces has an ENORMOUS impact on the resulting cleanliness. This property is called DWELL TIME. For most disinfectants, this takes several minutes. For example, both Lysol and Chlorine Bleach take a whopping 10 minutes to effectively disinfect surfaces. Newer disinfectants have entered the market that are based on Hydrogen Peroxide.
The product that we primarily use is called Oxivir. Oxivir is available in three formats: a pre-moistened wipe and a ready-to-use quart sized spray bottle called Oxivir Tb, and gallons of concentrated disinfectant called Five 16.
Oxivir Five 16 is so named because it has a 'five' minute dwell time at 1:16 dilution. Oxivir Tb in both wipe and spray form has only a one minute dwell time, which is reasonable for staff and building occupants to use effectively without too much hassle. The 'Tb' in the name refers to Tuberculosis. Tuberculosis is of the mycobacterium family which are notoriously difficult to eliminate with disinfectant products. Oxivir Tb does eliminate Tuberculosis, so by default anything less difficult to kill is toast.
Another benefit of Oxivir is that is doesn't evaporate too quickly. Here is a quick video showing two competing products and their evaporation time. If the product dries prior to the required contact time, you either need to re-apply or face the reality that you didn't fully disinfect the surface.
