Use of Cleaning Agents

It is recommended to use an appropriate cleaning agent suitable for cleaning agricultural sprayers.
• Cleaning agents containing a suitable lube or conditioner are recommended.
• If for some reasons this is not available, and triple ammonia water is used instead, it is important to rinse the liquid
system immediately after, and add some lubricant to the rinsing water to prevent ball valves etc. seizing up.
• Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect valves and seals from drying or seizing up.
