Which of the following is a disadvantage of Flowable (F) that may require extra cleaning after use?

• A. Spray mix needs constant agitation
• B. Requires frequent cleaning after use
• C. Non-corrosive to metal surfaces
• D. Long shelf life

Answer: (B)

Flowable formulations are suspensions of solid particles in liquid. Because those particles can settle and cling to tank walls, hoses, and nozzles, residues often remain after spraying. If these residues dry or build up, they can cause clogs and cross-contamination, so extra cleaning after use is necessary to flush out the remaining material and prevent equipment issues. The other points describe performance during spraying or general product advantages, not the post-use cleaning burden: constant agitation is a requirement to keep the suspension uniform during application, non-corrosive to metal surfaces is a positive trait, and long shelf life is also an advantage.
