My HVAC technician cleans my air conditioner’s evaporator coil with a special spray

I know some people who think that they can use bleach to clean literally anything.

They read online that it kills viruses, bacteria, and fungus like mold and mildew.

It’s easy to assume that bleach is the perfect cleaning agent for nearly every application due to its alleged versatility across the board. Unfortunately, bleach isn’t as great as it’s made out to be. The fumes are toxic, especially in high concentrations. Even though it is a good virucidal and bacteriostat, people don’t know that it doesn’t always kill everything on immediate contact. Like hydrogen peroxide, bleach needs to sit on a surface for varying degrees of time to kill everything that isn’t wiped away at first by your bleach soaked rag. It also leaves behind gross odors when it reacts with organic material like virus, bacteria, and mold. You might think that your surfaces are still dirty simply from the odor left behind after you finish your initial cleaning. But worst of all, bleach has the ability to damage and corrode metal surfaces. Because air conditioners are prone to mold growth inside, some people reach for bleach in the hopes that it will solve all of their air quality concerns. In the process, they end up destroying their evaporator coils because the metal gets corroded and rusted out upon contact with the chemical. This is why HVAC technicians use special aerosol spray cleaners for disinfecting heating and cooling equipment. When I need my evaporator coil cleaned, I let my HVAC technician handle the chore so I don’t damage my air conditioner.
