What is the recommended method for cleaning nozzles and sprayers?

The recommended method for cleaning nozzles and sprayers is to use compressed air or wash out the sprayer. This approach is effective because it helps remove any residues and blockages that could affect the performance of the sprayer during future applications. Compressed air can dislodge particles that are stuck inside the nozzle, while washing out the sprayer with clean water can flush out any remaining herbicide or other chemicals that might contaminate the next mix.

Using hot water only is not as effective because while it may dissolve some residues, it might not fully remove all contaminants, especially if they have dried or bonded within the sprayer components. Wiping with a cloth is insufficient for thorough cleaning, as it does not address the internal sections of the nozzles and lines where herbicide can linger. Soaking in a chemical solution may pose safety risks and could potentially damage the sprayer components if not done with the right types of solutions. Therefore, the combined method of using compressed air and washing out the sprayer thoroughly ensures proper maintenance and functionality for future applications.
