How should spray nozzles be cleaned?

• A. With a soft brush
• B. With a steel wire brush
• C. With a cloth
• D. With compressed air

Answer: (A)

Cleaning spray nozzles with a soft brush is best because it gently removes built-up residues from the tip and tiny passages without damaging delicate surfaces. The soft brush can reach into small crevices and dislodge deposits without scratching or deforming the nozzle. A steel wire brush is too harsh and can gouge or deform the nozzle and even leave bristles behind. A cloth may wipe the exterior but won’t reliably clean the internal orifice and can leave lint. Compressed air can push debris deeper or cause safety issues if not used with proper filters and precautions. So, a soft brush provides effective cleaning while protecting the nozzle.
