Which of the following is a step in the cleaning process after filling the tank with a cleaning agent?

Allowing the solution to circulate through the tank is an essential step in the cleaning process after filling it with a cleaning agent. This circulation ensures that the cleaning agent comes into contact with all surfaces of the tank, including hard-to-reach areas, thereby effectively removing residues and contaminants that may have built up during previous uses. The movement of the solution helps to dislodge any debris or residues, making the cleaning process far more thorough and effective.

In the context of managing industrial weed control equipment, proper cleaning is crucial not only for maintaining the equipment's functionality but also for preventing cross-contamination between different chemicals used in various applications. By ensuring that the cleaning solution circulates fully, operators can better guarantee that their equipment is clean and ready for its next use.
