The Science of Clean: Why Targeted Disinfection is Replacing the Overuse of Chemicals

For decades, the commercial cleaning industry operated under a flawed assumption: if an office smelled like strong bleach and harsh chemicals, it was clean. However, facility management has evolved significantly. Today, premium office cleaning is no longer just about visual appearance or a sterile smell; it is fundamentally about protecting occupant health and indoor air quality.

The industry is rapidly shifting away from the indiscriminate overuse of harsh chemicals and toward a smarter, healthier approach: Targeted Disinfection.

Here is why facility managers in Metro Detroit are upgrading to this health-focused cleaning methodology, and how Reach Building Services implements it to keep your workplace truly safe.

The Problem with "Spray and Pray" Cleaning

Unprofessional cleaning crews often walk into a facility and spray strong chemicals indiscriminately over every visible surface. This overuse of disinfectants is not only wasteful, but it actively degrades your building’s Indoor Air Quality (IAQ). Continuously breathing in airborne chemicals and artificial fragrances can cause respiratory irritation and discomfort for your employees.

Furthermore, simply spraying a chemical and immediately wiping it away does not actually sanitize the workspace. Wiping down a surface right after spraying it with a disinfectant is one of the most common mistakes made by untrained cleaners.

The Master Key: Understanding "Dwell Time"

The secret to true sanitization is a concept known as "dwell time" or "contact time." Dwell time is the specific duration a disinfectant must remain wet on a surface to reach its peak effectiveness. Depending on the specific chemicals comprising the product, this necessary wet time can range anywhere from 30 seconds to 10 minutes. Disinfectants must stay visibly wet on the surface for this entire duration to successfully kill targeted germs and viruses.

At Reach Building Services, our tenured staff is rigorously trained in the science of cleaning. We utilize precise chemical dilution systems and strictly adhere to manufacturer dwell times. We know that skipping the clock means leaving pathogens behind.

The Targeted Disinfection Strategy

Instead of dousing your entire office in unnecessary chemicals, our crews employ Targeted Disinfection. This protocol relies on a deliberate two-step process:

• Clean First: Disinfectants work best on surfaces that are already free of dirt. We first clean surfaces with commercial cleaners containing soap or detergent to decrease the number of germs and remove physical dirt.

• Target High-Touch Points: We then apply EPA-registered disinfectants to the surfaces most likely to spread illness. This focuses heavily on high-touch surfaces such as door handles, counters, elevator buttons, stair rails, and shared touchpads.

By focusing the chemical application only on the critical vectors where germs actually spread, we drastically reduce the total volume of harsh chemicals introduced into your facility's environment while maximizing health protection.

Health Over Appearance

Your cleaning contract should do more than just make your floors shine; it should actively reduce office sick days and protect the health of your team. By partnering with a company that understands targeted disinfection, proper chemical dilution, and crucial dwell times, you ensure a workspace that is definitively clean, completely safe, and ready for business.
