1. What is the primary purpose of pre-vacuuming carpet before wet cleaning?
A. To increase carpet moisture
B. To remove dry particulate soil
C. To neutralize alkaline chemicals
D. To soften carpet fibers
Answer: To remove dry particulate soil
Rationale: Thorough pre-vacuuming removes loose and dry particulate soil
before moisture is introduced, improving the effectiveness of subsequent
cleaning steps.
2. Which carpet fiber is generally considered a synthetic fiber?
A. Wool
B. Cotton
C. Nylon
D. Silk
Answer: Nylon
,Rationale: Nylon is a synthetic polymer fiber widely used in residential and
commercial carpeting.
3. What is the main function of a surfactant in a carpet-cleaning solution?
A. Increase carpet density
B. Reduce surface tension and assist soil removal
C. Permanently dye the carpet
D. Increase fiber strength
Answer: Reduce surface tension and assist soil removal
Rationale: Surfactants help cleaning solutions wet the fibers and interact with
oily soils so they can be suspended and removed.
4. Which type of soil is generally most effectively removed by vacuuming?
A. Dissolved salts
B. Dry particulate soil
C. Deeply bonded oily soil
D. Chemical residues
Answer: Dry particulate soil
Rationale: Vacuuming is particularly effective at removing loose particulate
material before a cleaning solution is applied.
5. Why should a technician inspect carpet before cleaning?
A. To determine whether the room needs painting
B. To identify fiber, construction, conditions, and potential risks
C. To determine the customer's income
D. To eliminate the need for testing
Answer: To identify fiber, construction, conditions, and potential risks
Rationale: Pre-inspection helps the technician select appropriate methods and
identify conditions such as color instability, wear, stains, or existing damage.
,6. Which fiber is a natural animal fiber commonly used in carpet?
A. Olefin
B. Polyester
C. Nylon
D. Wool
Answer: Wool
Rationale: Wool is a natural protein fiber obtained from sheep and is used in
many high-quality carpets and rugs.
7. What is the primary purpose of agitation during carpet cleaning?
A. To physically help distribute cleaning agents and loosen soil
B. To permanently flatten the carpet
C. To remove carpet backing
D. To prevent vacuuming
Answer: To physically help distribute cleaning agents and loosen soil
Rationale: Appropriate agitation improves contact between the cleaning
solution and contaminated fibers and assists soil suspension.
8. Which cleaning method typically uses a cleaning solution followed by
mechanical recovery of suspended soil?
A. Extraction cleaning
B. Dry dusting
C. Carpet installation
D. Color repair
Answer: Extraction cleaning
Rationale: Extraction cleaning uses solution to suspend soil and equipment to
recover the resulting liquid and contaminants.
9. What is one major advantage of effective vacuuming before cleaning?
, A. It eliminates all stains
B. It reduces the amount of soil that must be removed through wet cleaning
C. It permanently changes fiber color
D. It increases drying time
Answer: It reduces the amount of soil that must be removed through wet
cleaning
Rationale: Removing dry soil first makes the subsequent cleaning process more
efficient and reduces the soil load placed on the cleaning solution and recovery
system.
10. What does pH measure?
A. Carpet density
B. Fiber diameter
C. Acidity or alkalinity
D. Moisture content only
Answer: Acidity or alkalinity
Rationale: The pH scale indicates how acidic or alkaline a solution is, which is
important when selecting cleaning chemistry.
11. A solution with a pH below 7 is generally considered:
A. Neutral
B. Acidic
C. Alkaline
D. Oxidizing only
Answer: Acidic
Rationale: On the conventional pH scale, values below 7 are acidic, 7 is neutral,
and values above 7 are alkaline.
12. Why is chemical dilution important in carpet cleaning?
