A sample from this course
One topic, as StudyPath teaches it.
Wet and dry cleaning concepts
Wet cleaning uses water and detergents to remove dirt, while dry cleaning employs non‑aqueous solvents to clean fabrics that are sensitive to water. Mastering the principles of solvent action, fabric compatibility, and cleaning mechanisms is essential for correctly diagnosing cleaning problems and selecting appropriate methods for the exam.
