IICRC UFT – UPHOLSTERY & FABRIC
CLEANING TECHNICIAN EXAM |250 Advanced-
Level Multiple Choice Questions with Answers &
Rationales
1. Which of the following fiber identification tests is considered the MOST reliable for
distinguishing protein fibers from cellulosic fibers?
A) Water absorption test
B) Burn test using a flame source
C) Bleach test with sodium hypochlorite
D) Solvent spot test with acetone
B) Burn test using a flame source (correct answer)
Rationale: The burn test (flame test) is a reliable field identification method. Protein fibers
(wool, silk) burn slowly, self-extinguish, smell like burning hair, and leave a crushable ash.
Cellulosic fibers (cotton, linen) burn quickly, smell like burning paper, and leave a soft gray ash.
2. A technician encounters a fabric labeled "S" for cleaning code. This means the fabric
should be cleaned with:
A) Steam and hot water extraction
B) Water-based cleaning agents only
c) Solvent-based (dry cleaning) products only
D) Any cleaning product the technician chooses
C) Solvent-based (dry cleaning) products only (correct answer)
Rationale: The "S" cleaning code indicates solvent-only cleaning. Water-based cleaners can
cause shrinkage, distortion, watermarks, or browning on fabrics with this code.
,3. What is the PRIMARY risk of using highly alkaline cleaning agents on wool upholstery?
A) Color brightening
B) Fiber swelling and felting due to disruption of the protein structure
C) Rapid drying that causes shrinkage
D) Increased static electricity buildup
B) Fiber swelling and felting due to disruption of the protein structure (correct answer)
Rationale: Wool is a protein fiber highly sensitive to alkalinity. High pH causes the cuticle
scales to open and interlock (felt), permanently damaging the fiber structure and causing
irreversible shrinkage.
4. The IICRC UFT standard recommends performing a pre-cleaning inspection that
includes which of the following as a PRIORITY?
A) Identifying the client's preferred scent for deodorizers B) Fiber identification, fabric
construction, colorfastness testing, and soiling type assessment C) Selecting the cleaning
equipment brand D) Measuring the square footage for pricing only
B) Fiber identification, fabric construction, colorfastness testing, and soiling type
assessment (correct answer)
Rationale: A thorough pre-cleaning inspection assesses fiber type, fabric construction, dye
stability, and soil type — all of which determine the appropriate cleaning method and chemistry.
5. Which of the following BEST describes "wicking" in upholstery cleaning?
A) The transfer of dye from one fabric area to another B) The migration of soil or residue from
deep within the fabric to the surface as the fabric dries C) The absorption of cleaning agent into
the foam cushion D) The spreading of wet foam across the fabric surface
B) The migration of soil or residue from deep within the fabric to the surface as the fabric
dries (correct answer)
Rationale: Wicking occurs when dissolved soils or residues travel upward through the fabric via
capillary action during drying, reappearing as spots or stains on the surface.
,6. A technician is cleaning a viscose (rayon) upholstery fabric. The MOST critical risk
associated with this fiber is:
A) High resistance to water B) Extreme weakness when wet, leading to distortion, shrinkage, and
pile crushing C) Sensitivity to dry solvent cleaning D) Low affinity for anionic surfactants
B) Extreme weakness when wet, leading to distortion, shrinkage, and pile crushing (correct
answer)
Rationale: Viscose/rayon loses up to 50–70% of its tensile strength when wet, making it
extremely vulnerable to distortion, pile crushing, and shrinkage from excessive moisture or
agitation.
7. Which type of upholstery fabric construction is characterized by loops of yarn on the
surface that, when cut, produce a velvet-like appearance?
A) Woven tapestry B) Cut pile (velvet/velour) C) Bouclé D) Jacquard
B) Cut pile (velvet/velour) (correct answer)
Rationale: Cut pile fabrics are created by cutting the loops of a pile weave, producing upright
fibers that create the characteristic soft, dense surface of velvet or velour.
8. When performing a colorfastness test on upholstery, the technician applies the cleaning
agent to an inconspicuous area and uses a white cloth. A positive result (safe to proceed) is
indicated by:
A) The white cloth shows a faint transfer of color B) No color transfer to the white cloth and no
change in the fabric's appearance C) The fabric becomes slightly lighter in color D) The cleaning
solution changes color
B) No color transfer to the white cloth and no change in the fabric's appearance (correct
answer)
Rationale: A successful colorfastness test shows no dye transfer to the white cloth and no visible
change (browning, lightening, running) in the tested area, indicating it is safe to proceed.
9. Which of the following pH ranges is MOST appropriate for cleaning protein fiber
upholstery (wool, silk)?
, A) pH 9–11 (alkaline) B) pH 4.5–6.5 (slightly acidic to neutral) C) pH 12–14 (strongly alkaline)
D) pH 7–9 (neutral to mildly alkaline)
B) pH 4.5–6.5 (slightly acidic to neutral) (correct answer)
Rationale: Protein fibers are isoelectric (most stable) at slightly acidic pH. Cleaning solutions in
the 4.5–6.5 range minimize swelling, dye bleeding, and fiber damage on wool and silk.
10. What does the term "pile reversal" (also called pooling or shading) refer to in
upholstery pile fabrics?
A) A permanent color change caused by UV exposure B) Permanent or semi-permanent change
in pile direction causing light/dark areas, not caused by soiling or staining C) The flattening of
pile from repeated sitting D) Dye migration from cleaning solution
B) Permanent or semi-permanent change in pile direction causing light/dark areas, not
caused by soiling or staining (correct answer)
Rationale: Pile reversal (shading/pooling) is a random change in pile direction that alters light
reflection, creating apparent color variation. It is a fabric characteristic, not a cleaning issue.
11. Which of the following describes the proper technique for applying cleaning solution to
prevent over-wetting of upholstery?
A) Pour the solution directly onto the fabric surface B) Apply solution to the cleaning tool
(sponge, brush, or cloth) and work it into the fabric in controlled amounts C) Saturate the fabric
to ensure deep cleaning of foam cushions D) Use a high-pressure spray to penetrate deeply soiled
areas
B) Apply solution to the cleaning tool (sponge, brush, or cloth) and work it into the fabric
in controlled amounts (correct answer)
Rationale: Applying solution to the cleaning tool rather than directly to the fabric gives the
technician precise moisture control, preventing over-wetting that can cause shrinkage,
browning, or wicking.
12. A client reports that their silk upholstery has developed water rings after a spill. The
technician should:
