Disinfection has become a buzzword in recent years, especially following the COVID-19 pandemic. But behind the marketing claims and brightly colored labels, there’s real science at work. Understanding what truly makes a disinfectant effective can help businesses make better choices when it comes to keeping their facilities clean and safe. Baker Sandoval Cleaning explores this further below:

What Is Disinfection?

Disinfection refers to the process of eliminating or reducing harmful microorganisms—such as bacteria, viruses, and fungi—on surfaces to a level deemed safe by public health standards. It’s not the same as cleaning (which removes visible dirt and debris) or sterilizing (which kills all microbial life). Disinfection focuses on reducing microbial load to prevent the spread of illness.

How Do Disinfectants Work?

Disinfectants kill or inactivate microbes by disrupting their structure or metabolic processes. The active ingredients in disinfectants vary, but common ones include:
– Quaternary Ammonium Compounds (Quats): Effective against most bacteria and enveloped viruses. Often found in general-purpose disinfectants.
– Bleach (Sodium Hypochlorite): A powerful and fast-acting disinfectant that kills a wide range of pathogens. Best for non-porous surfaces.
– Hydrogen Peroxide: Breaks down into water and oxygen, making it an eco-friendlier choice while still being effective.
– Alcohol (Ethanol or Isopropyl): Quick-acting and effective against many bacteria and viruses, though it evaporates quickly.
The key is contact time—the amount of time the disinfectant must stay wet on a surface to be effective. Many products require 5–10 minutes of wet contact to work properly, which is why simply spraying and wiping immediately isn’t enough.

What Surfaces Need Disinfecting?

High-touch surfaces are the priority when it comes to disinfection. These include:
– Door handles
– Light switches
– Desk surfaces
– Phones and keyboards
– Restroom fixtures
– Breakroom counters
Disinfecting low-touch surfaces like walls or ceilings is generally unnecessary unless there’s been a contamination event.

The Role of Dwell Time

Dwell time (also called “wet time”) is a critical factor in effectiveness. A product may claim to kill 99.9% of germs—but only if left on the surface for the required time. Janitorial professionals are trained to follow these instructions to the letter, ensuring the disinfectant has the chance to do its job.

Proper Use is Key

Even the best disinfectant won’t work if not used correctly. Here are a few best practices:
– Pre-clean dirty surfaces. Dirt and grime can block disinfectants from reaching microbes.
– Follow label instructions. Always read and apply according to the manufacturer’s guidelines.
– Use appropriate PPE. Gloves and sometimes masks or goggles may be necessary, especially with strong chemicals.
