Which item should never be used to clean a nozzle?

• A. Pin
• B. Soft brush
• C. Water
• D. Alcohol wipe

Answer: (A)

Nozzle maintenance is about preserving the precise orifice so the spray pattern and droplet size stay consistent. A pin should never be used to clean a nozzle because it can scratch or burr the tiny opening, permanently altering the spray and causing improper coverage or drift. Safe cleaning methods include flushing with water to clear blockages, using a soft brush to remove debris around the orifice, and wiping the exterior with an alcohol wipe to remove residues. If a nozzle is clogged, use manufacturer-approved cleaning tools or replace the nozzle rather than probing it with a pin.
