What should you flush the ULV machine with after use?

Flushing the ULV (Ultra-Low Volume) machine with isopropyl alcohol after use is appropriate because isopropyl alcohol is effective in cleaning and dissolving residues that may remain in the machine after applying pesticides. This solvent helps to ensure that any remaining chemicals are thoroughly removed, preventing cross-contamination when the equipment is used with different products in the future.

Isopropyl alcohol is also less corrosive than some other solvents, making it suitable for maintaining the integrity of the machine's parts over time. It evaporates quickly, minimizing downtime between uses while ensuring that the equipment is ready for its next application without any residual pesticide affecting performance or safety.

Other options, such as water, may not effectively remove all pesticide residues, while chemical detergents and petroleum-based solvents could potentially damage the equipment, risking its functionality or safety. Hence, using isopropyl alcohol is a best practice for ensuring that ULV machines are properly cleaned and maintained.
