There are many methods of cleaning to reduce and eliminate the threat of the coronavirus (COVID-19) in office buildings and medical practices. The EPA has a list of approved disinfectants to use on this strain of the coronavirus, but many commercial cleaning companies are finding it difficult to apply the product and leave it wet for the entire dwell time. Many times, when applying a disinfectant that has a dwell time of more than 5 minutes, the disinfectant will need to be applied a second time, so as to observe the entire dwell time, or allow the surface to remain wet during the entire dwell time. If the surface dries before the entire dwell time is observed, you must start over and apply the disinfectant for an additional 10 minutes.
Restoration companies use different equipment to apply disinfectants to hard-to-reach areas, such as ceilings, high walls, and areas that are generally difficult to reach. Foamers are an excellent way to achieve this result. A foamer is a piece of equipment that changes a liquid into a foam (the same applies to liquid hand soaps that instantly turn to foam when the plunger is pushed). This equipment is very useful because the foam allows the disinfectant to stay wet against a surface much longer than it would in a liquid state.
There are a couple of downsides of using a foamer, though. The first it the product may not be able to applied upside down, so applying this to a ceiling must be done at an angle. The second is that the foam generally comes out unevenly, so you may need more than one pass to properly apply it. The notabe downside of using a commercial foamer to apply a disinfectant is there is generally a sizable mess to clean up after the dwell time is observed.
Despite the downsides, there are some great reasons to use a foamer to apply a disinfectant to kill the coronavirus.
