How’s your GIANT filter? By Michael Zachery

Did you know that carpet cleaning is largely an unregulated industry?

In many places, someone can legally call themselves a carpet cleaning technician without formal training, classroom education, certification, or a strong understanding of cleaning chemistry, fiber science, or the principles of a healthy indoor environment. Someone can even operate for decades without ever receiving meaningful industry education.

That may help explain why so many people have a negative perception of the carpet cleaning industry. They may have hired several different companies over the years and assume that what they experienced represents professional carpet cleaning. But simply having someone show up with a machine does not mean that the science and expertise behind professional cleaning are being applied.

So why is professional carpet cleaning important?

The textiles throughout your home—including carpeting, rugs, upholstery, and other fabrics—can collect and hold dust, allergens, soil, and other particulate matter. They are a significant part of the indoor environment and, in a sense, function as highly effective passive filters.

Think about an old pair of pants. If they haven’t been washed for years, you wouldn’t expect them to remain clean simply because they were originally clean. Your home’s textiles are no different. They require periodic cleaning to remove the soils and contaminants they accumulate through everyday use.

Keep in mind that your carpets cover a large portion of your home’s floor space and can act much like a large air filter. They capture particles from the air, foot traffic, pets, spills, and everyday activity. Like any filter, they need to be properly maintained and cleaned. Your main cleaning is using an effective vacuum on a regular basis. But at some point it’s time to call a genuine professional. 

Yet because our industry often has no educational requirements, many technicians have never been taught the science behind cleaning for a healthy indoor environment. This lack of knowledge can contribute to poor results, reinforce negative perceptions of the industry, and potentially create additional problems in the home.

For example, excessive moisture can leave carpeting wet for too long. When carpet remains damp, it can contribute to bacterial growth and unpleasant odors. Bacteria and other contaminants can produce odors, while improper cleaning methods may leave behind residues that attract soil and cause rapid resoiling.

Many homeowners have experienced spots returning, strong fragrance odors, crunchy carpet fibers, discoloration, or carpet that feels sticky after cleaning. These issues can indicate that the cleaning process was incomplete, the wrong products were used, too much solution was applied, or the carpet was not properly rinsed and dried. They are often signs that the work may not have been performed by a properly trained professional.

Drying time is another important consideration. Carpeting that remains excessively wet for hours—or, worse, days—can create an environment where microbial growth and odors become concerns. Professional cleaning isn’t simply about getting something “clean.” The process, chemistry, moisture management, extraction, and drying all matter.

In my opinion, choosing a carpet cleaning company shouldn’t be based solely on price or how quickly someone can get a machine through your home.

Look for a company that can demonstrate education, training, experience, knowledge of cleaning chemistry and fibers, and a genuine understanding of how professional cleaning affects your home environment.

A professional cleaner isn’t simply someone who happens to own a carpet cleaning machine.

There’s a lot more science behind clean than most people realize.
