There is a lot of hype about the proper way to disinfectant with the attention is focused on electrostatic and fogging. The one thing these two methods have in common is they spray a liquid. The list of how they are different is much bigger. The intention is not to bore you with a long white paper but to highlight what you need to know to make your decision about the best way to protect your staff and customers.
When it comes to applying a disinfectant to surfaces, both accomplish the task. They both do it differently and provide different levels of protection. Regardless of what device is used for spraying, the important first step that is often forgotten is cleaning the surfaces. If you do not all you are doing is applying the disinfectant to the dirt, grease, grim, dirt and dust.
Do you select the spraying device before the disinfectant? NO
At the end of the sprayer where the liquid comes out is a nozzle. The hole in the nozzle can have a variety of sizes. Most of the time the hole is 35mm to 90mm. The nozzle size is critical to attain the right size droplet to evenly cover the surface. Different disinfectant performs differently based on the nozzle size. Match the disinfectant requirements to attain the protection you expect. NOTE: The instructions on the label are required by the EPA. You must follow the instructions not only to kill the germs but protect the surface, the air, and the people.
The nozzles also come in a variety of materials. A variety of plastics and metals. If you intend to spray a chemical, caustic, toxic disinfectant – you need to know what if the disinfectant is more caustic to plastics or metals. Frequently this is difficult to determine until you have already purchased the sprayers, but you will soon realize the problem when you must replace the nozzle repeatedly. Remember from above, the right size nozzle is critical to getting the protection offered by the disinfectant. As soon as the nozzle starts to wear out, your level of disinfecting is reduced.
Are foggers better than electrostatic?
It depends on the surfaces you want to protect. Foggers are generally used outdoors for insects. They spray exceedingly small droplets that are easily directed by wind currents and gravity. If you want to disinfectant a floor, foggers are best (at long as there is no wind).
- Foggers are best used in HVAC systems – tight spaces where you can force air into tight spaces. Foggers are not as effective in any area with vertical surfaces like table and chair legs, fitness centers with vertical equipment, etc.
Electrostatic sprayers deliver charged droplets meaning the liquid has an electrical charge. The charge provides a couple benefits:
- As the liquid is sprayed it will wrap around corners. For example, imagine a restaurant. The electrostatic liquid will wrap around the edges of the tables. This makes for amazingly fast spraying to cover large area is but also produces a false sense of security. In the hands of an inexperienced technician, it’s hard to tell if the invisible actually reaches all of the surface that people may touch. (That is why onsite testing is critical to determine if the treatment is being applied properly.
- The electrical charge in the droplets is attracted to surfaces providing a more even layer of protection and the liquid bonds better with the surface. Think of painting a car. Using a spray can would take a long time compared with an electrostatic sprayer.
What is the right way to spray?
The real question – what is the right way is to “DISINFECT”! As we said earlier, the disinfectant determines the sprayer. But it also determines the spray protocol. The right protocol is determined by the disinfectant, the surface(s) and the size of the space. In tight spaces, electrostatic and foggers are going to waste a lot of disinfectant, provide uneven coverage and reduce the level of protection. The right answer is to use the best sprayer for the surfaces requiring protection. This is a combination of electrostatic, fogger, hand sprayers and wipes.
How do I know if the surface is protected?
Testing is the only way. Disinfectants are invisible so you cannot see them in action. If your surfaces are not tested, you are spending a lot of time and money for protection you are probably not getting.
Using the right disinfectant for the right surface is a science. When you want to protect your staff and customers from germs, odors, mildew, or mold, leave it to the experts at MicroForce.
