What is a critical step to take before using the sprayer?

Thoroughly rinsing the sprayer with clean water is a critical step before use because it helps ensure that any residual chemicals from previous applications are removed. This is vital for several reasons: it prevents the unintended mixing of chemicals, which could potentially lead to harmful reactions or reduced efficacy of the intended product. Additionally, it protects the environment by preventing chemical contamination, particularly if the sprayer is being used in sensitive natural areas or right-of-way applications. Proper rinsing also prolongs the life of the sprayer by preventing corrosion or buildup due to leftover chemicals. Therefore, starting every spraying session with a clean sprayer establishes a safe and effective application process.
