Carpet Cleaning Technician flashcards

33 cards. Read the term and the definition here. The deck at the top of this page is optional.

Pre-inspection purpose

A documented walkthrough before cleaning that identifies fiber, construction, soiling, damage, and pre-existing defects, and sets written expectations with the customer.

Documenting pre-existing damage

Record burns, stains, wear, delamination, fading, and furniture marks in writing and photos before cleaning so pre-existing defects are not attributed to the technician.

Fiber identification tests

Burn and chemical tests on spare fibers reveal fiber type; burn behavior, ash, and odor distinguish protein, cellulosic, and synthetic fibers.

Traffic lane mapping

Marking high-soil zones during pre-inspection lets the technician concentrate prespray, dwell time, and agitation where soil is heaviest.

Nylon fiber properties

Strong, resilient synthetic that accepts acid dyes; acid spotting agents can strip its color, and it benefits from stain protectant.

Polyester (PET) properties

Inherently stain-resistant and low-moisture synthetic, but oil-loving and prone to matting and pilling; less resilient than nylon.

Olefin properties

Solution-dyed, hydrophobic polypropylene used in loop pile; resists moisture-based stains but crushes and attracts oil; low melting point.

Wool fiber care

Protein fiber sensitive to high pH, chlorine bleach, and strong alkalis; use neutral or wool-safe products with controlled moisture and drying.

Cut pile vs loop pile

Cut pile shows footprints and matting but resists snagging; loop pile resists crushing but snags and unravels if pulled.

Carpet backing types

Action backing, jute, polypropylene, and urethane foam vary in water sensitivity; jute and foam demand lower moisture and faster drying.

Particulate soil removal

Sand and grit are removed best by dry vacuuming before wet cleaning; wetting grit first drives it deeper into the pile.

Oily soil removal

Grease and cooking oil need surfactants and solvents with dwell time; alkaline presprays saponify oils but risk damage on wool and pH-sensitive dyes.

Protein stain treatment

Blood, milk, and egg require cool water and enzyme or neutral digesters; hot water or high pH sets protein stains permanently.

Urine contamination

Urine penetrates backing and pad, leaving salts and odor; surface cleaning is insufficient and sub-surface extraction or pad replacement is often needed.

Filtration soiling

Dark lines along walls and doorways where air passes through carpet edges; embedded carbon soil that is rarely fully removable.

Wicking

Soil or stain drawn back to the pile surface as carpet dries; controlled by thorough extraction, low moisture, and rapid airflow.

Four cleaning principles

Chemical action, mechanical action, temperature, and dwell time; increasing one factor generally allows reducing another while maintaining cleaning results.

pH and cleaning

Alkaline cleaners above pH 7 attack oils and grease; acidic cleaners below pH 7 neutralize residues and correct browning and high-pH damage.

Target drying time

Carpet should dry within roughly 6 to 12 hours; slower drying invites wicking, odor, mildew, and delamination.

Over-wetting consequences

Excess solution causes delamination, shrinkage, prolonged drying, and odor; slow overlapping dry passes maximize water recovery.

Chemical residue and resoiling

Detergent left in the pile attracts soil; thorough rinsing or pH balancing reduces rapid resoiling after cleaning.

Prespray dilution

Traffic-lane prespray must be mixed at the label ratio; over-concentration leaves sticky residue that attracts soil and dulls the pile.

Defoamer function

Added to the recovery tank to collapse foam; excess foam reduces vacuum lift and leaves solution behind in the carpet.

Solvent spot removers

Dissolve oils, tar, and grease; apply sparingly with ventilation and never near open flame or pilot lights due to flammability.

Enzyme digesters

Break down protein and organic stains; require dwell time and moisture and should not be mixed with strong chemicals that deactivate them.

Reducing agents

Sodium metabisulfite and similar reducers remove oxidizing stains such as coffee and tea; test first because they can strip dyes.

Oxidizing agents

Hydrogen peroxide-based products brighten and remove color-based stains but can bleach dyes, especially on wool and natural fibers.

Standard cleaning sequence

Pre-inspection, dry vacuum, spot treatment, prespray, dwell, agitation, extraction, grooming, drying, and post-inspection.

Dry vacuuming importance

Slow, overlapping vacuum passes remove most dry particulate soil before liquid is applied, preventing grit from being driven deeper.

Prespray dwell time

Prespray must remain wet on the pile for the label-specified dwell time; letting it dry reduces effectiveness and can leave residue.

Agitation purpose

Groomers, rotary brushes, and pile brushes break soil loose for extraction; excessive agitation on wool or loop pile causes fuzzing or snagging.

Low-moisture cleaning

Encapsulation and bonnet methods dry quickly and suit light commercial maintenance, but remove less deep soil than hot-water extraction.

Post-inspection steps

Groom the pile, verify stain results, check for wicking, position air movers, and review drying time and aftercare with the customer.
