Pseudoscience and carpet cleaning...

[Mikey P]

According to GPT,

A system of beliefs, theories, or practices that claims to be scientific and factual but lacks the evidence, methodology, or principles of legitimate science.

Key Characteristics of Pseudoscience:​

• Lacks empirical support: Not backed by controlled, repeatable experiments or peer review.
• Does not follow the scientific method: Relies on anecdotal evidence, vague claims, or emotional appeals.
• Cannot be reliably tested or falsified: The claims are often too broad, vague, or flexible to be proven wrong.
• Resists correction or criticism: Proponents often dismiss valid scientific objections or ignore contrary evidence.
• Uses scientific-sounding language: To appear credible while lacking true scientific foundation.

• Examples include astrology, homeopathy, and many "miracle" health products without clinical validation.
  
  
  So with that, what elements of our industry relies on or is based on Pseudoscience
  
  I'll toss some out there to get this conversation going...
  
  
  
  
• 4 to the Door or 2.5 hose
• TACT/CHAT
• Wand jetting- flow, number of jets, distance from carpet etc
• Deep flushing for urine removal
• Peroxide effectiveness on germ removal
• Enzymes effectiveness on germ removal

This one faded from view a few decades back:

The "Arrhenius rule" is a simplification of the Arrhenius equation, which states that for many chemical reactions, the reaction rate roughly doubles for every 10 degree Celsius (or Kelvin) increase in temperature. This rule of thumb is often used as a quick check for calculations involving the Arrhenius equation, though it's not always perfectly accurate


This was translated as:

"Every 18 degrees over 118 (how that conversion came about I'm not sure) cleaning power doubles"

The truck mount guys with fuel burners (Steamway and Prochem) and the upholstery cleaning equipment manufacturer (Kleenrite) used this extensively to sell their machines, and it made its way into IICRC classes.

The only way this really applies to what we do is how oxidizers and reducers work on stains.

Another one related to heat:

"Cleaning with temperatures over 212 f sanitizes carpet"

To do this you would have to:

1. Have a temperature of 212 hit the carpet. Since temperature sensors on machines are read at the hottest spot of water in the equipment system, it doesn't account for the cooling effect of last step chemical injections (usually drops about 20 f), then the heat loss through hoses and fittings, and especially the heat loss that occurs once the cleaning solution exits the wand jets until the solution hits the carpet.

2. Then IF (a big IF) the cleaning solution hitting the carpet is still over 212 f, it would need to remain at that temperature for a full minute. The vacuum pass of the cleaning tool rapidly cools the carpet at that point, so this is nearly impossible to acheive.

It is far more likely that by warming the carpet during the hot water extraction process, the water and unremoved contaminants would now experience accelerated microbial growth.

This is evident when post cleaning odors occur where animal hair is present, as one example.

An Aerotech and a Rotovac could accomplish that...

Trust the science, bro!
