Which statement about dry developer relates to ease of removal after inspection?

• A. It requires less handling
• B. It adheres strongly
• C. Easily cleaned from the surface after inspection
• D. It bonds permanently

Answer: (C)

The main idea is how easily dry developer can be removed after the inspection. Dry developer is a light powder used in penetrant testing to create a contrasting background so any cracks or flaws drawn by the penetrant stand out. After the test, you want the surface to be clean and ready for any follow‑up steps, so the developer should come off without leaving residue or masking defects. Dry developers are designed to be easily cleaned from the surface—brush, air blow, or gentle wipe typically remove it without harsh effort. If the developer adhered strongly or bonded permanently, removal would be difficult and could leave residues that cause false indications in future inspections. Therefore, the description that it can be easily cleaned after inspection best matches its practical use.
