A sprayer should be cleaned after ____________ days(s) of use.

Cleaning a sprayer after each use is crucial for maintaining the equipment's performance and ensuring the effectiveness of the chemicals being applied. Proper cleaning prevents chemical residue build-up, which can lead to cross-contamination of different pesticides or herbicides. This not only protects future applications from being compromised but also ensures that residues do not harm non-target organisms or the environment.

Additionally, regular cleaning helps extend the life of the sprayer by preventing clogs and wear caused by leftover chemical materials. It is a fundamental best practice in pest control to thoroughly rinse and clean all parts of the sprayer, including the tank, hoses, and nozzles, after every use to maintain efficiency and safety standards in pest management practices.
