Which practice is NOT recommended for nozzle cleaning?

• A. Use metal brushes and picks
• B. Use a soft-bristled brush
• C. Use manufacturer-recommended cleaners
• D. Rinse with clean water

Answer: (A)

Keeping nozzles clean is essential to maintain a consistent spray pattern and prevent clogging. Using metal brushes and picks can scratch or gouge the delicate nozzle and its passages, which can alter the spray, cause leaks, or reduce performance. This makes metal tools an unsuitable choice for nozzle cleaning. In contrast, a soft-bristled brush removes deposits without scratching the surfaces, manufacturer-recommended cleaners are formulated to be chemically compatible with nozzle materials, and rinsing with clean water helps flush away any residues. Together, these practices protect nozzle integrity and ensure reliable spray performance.
