What is the correct sequence for cleaning spray equipment after use?

• A. Wipe exterior with cloth.
• B. Rinse with dirty water, then drain.
• C. Fill with water and spray to clean.
• D. Drain, flush with clean water, collect rinse water, and dispose according to label; clean nozzles and filters.

Answer: (D)

The main point is removing all pesticide residues from the equipment in a safe, environmentally responsible way. Start by draining the tank contents so most of the product is removed. Then flush the system with clean water to wash out any remaining residues from the tank, hoses, and pumps. Collect the rinse water and dispose of it exactly as the label directs to prevent harming people, non-target organisms, or the environment. After that, clean the nozzles and filters to remove any buildup and ensure proper spray performance next time. Exterior wiping alone won’t reach interior parts, and using dirty rinse water would reintroduce contamination, so following this sequence is essential.
