These 10 free RCT questions are organized by exam domain, so you can see how each part of the Rug Cleaning Technician (RCT) blueprint is tested. Reveal the answer and explanation under each question.
A loose fringe sample burns with a paper-like odor and leaves light, fluffy ash. Under a microscope, its fibers resemble twisted ribbons. The rug's pile has not been sampled. Which entry belongs in the inspection record?
Correct answer: C - Cotton fringe; the pile needs separate identification.
Fine powder keeps collecting beneath a hand-tufted rug despite repeated dust removal. Its cloth secondary backing has begun to bubble and separate. Which condition best accounts for both findings?
Correct answer: D - Deterioration of the adhesive securing the backing.
An office's coarse-loop wool rug has oily traffic-lane soil. A tested detergent releases the soil with gentle agitation, but a powered brush catches the loops. Inspection supports aqueous cleaning of the entire construction, and floor protection, extraction and drying are available. Choose the cleaning plan that fits these findings.
Correct answer: C - Vacuum by plain suction, gently precondition, then use controlled spray extraction.
Presprays A and B both measure pH 8.5 at their labeled use dilutions. In a laboratory comparison at the same temperature, equal sample volumes require 1 mL and 4 mL, respectively, of the same standardized acid solution to reach pH 7.0. What does the difference reveal?
Correct answer: D - B has greater acid-neutralizing capacity over the tested interval.
An 8 L working-capacity tank contains a fresh batch of 5.00 L water and 200 mL prespray concentrate. The label specifies 20 mL concentrate per liter of water and permits correction by adding water. No other chemical is present. An empty, suitable 12 L tank is available. Which plan achieves the labeled dilution without exceeding tank capacity?
Correct answer: A - Transfer the batch to the 12 L tank, then add 5.00 L of water.
At a rug-washing station, an acidic spotter is accidentally poured into a bucket containing hypochlorite bleach. Two workers develop coughing and burning eyes; both can leave unaided. What takes priority?
Correct answer: D - Move everyone out of the affected area and obtain emergency assistance.
The pile of a sound hand-knotted rug tolerates a powered vacuum brush. At the ends, the cotton fringe continues directly from the warp yarns. How should the technician handle dry-soil removal along those borders?
Correct answer: B - Protect the fringe and use nonrotating suction on the adjacent pile.
Final inspection records a relative-scale moisture reading of 26 in a rug's thick foundation and 11 on a documented dry sample of matching construction. Repeated readings use the same meter, mode and setup. The pile feels dry. How should the technician interpret the result?
Correct answer: B - Foundation dryness needs further assessment; the readings are not water percentages.
A customer sees dark patches in a recently cleaned, fully dry cut-pile rug. From the opposite end, those patches look lighter than the surrounding pile. The tufts in the patches lean in a different direction. The appearance is best explained by:
Correct answer: A - Unequal light reflection from differently oriented pile.
A wool rug removed from storage has small bare patches and silken cases in its folds. A nearby pheromone trap has caught no adult clothes moths. How should these findings affect the inspection?
Correct answer: C - Inspect concealed folds for larvae and fresh feeding despite the empty trap.
