Chapter 1 – Introduction

Low Moisture Cleaning In the world of carpet cleaning, there remains a systemic debate…more water or less water. Technologies are changing rapidly as advances in chemicals and equipment race forward.

Chapter 2 – Definitions and Industry Terms

Detergency Detergency is the imparting of free-flowing abilities to undesired foreign   substances without damaging the material to which they are attached. Independently or collectively, it is created from four all-encompassing elements: Chemistry Heat / Temperature (Electromagnetic Energy) Agitation (Mechanical Energy) Time (which is always a factor). The strength of each element is accumulative with the... View Article

Chapter 3 – Processes

All cleaning process should begin with dry soil removal and vacuuming Dry carpet cleaning systems are more accurately known as "very low moisture" (VLM) systems, relying on dry compounds complemented by application cleaning solutions, and are growing significantly in market share due in part to their very rapid drying time,[4] a significant factor for 24-hour commercial...

Chapter 4 – What Is Soil?

Basically, anything foreign to the construction of the fiber. Where do we find the soil?  Most soil will be at the entrance. One study showed it takes 15 steps or about 45 feet.   Walk off mats both inside and outside will help with keeping the soil contained. Proctor and Gamble did a study and found... View Article

Chapter 5 – Pre-Vacuuming

This is the MOST EFFECTIVE WAY of removing soil. In all classes, that we teach this is usually the least welcome news but it is critical, especially in low moisture and VLM. Let us see why pre-vacuuming is such an advantage. All the general carpet-cleaning methods rely on some sort of solvency. By that, we... View Article

Chapter 6 – Soil Suspension and Agitation

So now we have removed insoluble soil, what’s next? Pre-conditioners Whether we are using a pre-spray, encapsulant, shampoo, or an absorbent compound we must be able to break down the water soluble and dry solvent soluble oily soils into suspension.  These can be applied with a variety of tools or methods including: Pump-Up Sprayers Battery/electric-Powered...

The absorbent compound method (also called dry cleaner method) is a cleaning process that employs an absorbent/adsorbent media that has been mixed with various cleaning ingredients which is applied to the carpet and agitated with any of a variety of specially designed machines. The absorbent media delivers the cleaning liquids to the fiber surface, the... View Article

Chapter 9 – Bonnet Brush Machine

This machine combines both the brush and bonnet. The brush gives the agitation and the bonnet picks up the soil. This works great with encapsulation. Here are some bonnets that can be used. Bonnet driver with Brush

Chapter 10 – Bonnet and OP Cleaning

Using a 175 RPM rotary or oscillating or orbital pad machine fitted with a drive brush or pad holder several different types of bonnets and pads are used to agitate, trap, or absorb to remove suspended soil.  Fiber pads  Absorbent, Adsorbent, and Microfiber pads  Bonnet: 175 RPM Swing Type Floor Machine  Chemstractor – Bonnet Sprayer...

Chapter 11 – Bonnet Cleaning With Steam Vapor

The steam vapor system employs the use of live, low moisture, high temperature steam vapor to release the soils entrapped upon and within the carpet fibers with minimal agitation.  High temperature steam vapor flows from the steam generator, through the bonnet and into the carpet.  The bonnet fabric becomes hot and moist, attracting and collecting...

Chapter 12 – Dry Foam Shampoo

Low moisture extraction cleaning (Most commonly known as dry foam) Some systems are self-contained and the cleaning process, that cleans carpet as well as extracts the soil-laden foam, is done simultaneously in a single forward pass. Other systems generate foam and then require a separate wet vacuuming process.   Depending on soil conditions and carpet type,... View Article
