What action is recommended if a duster's spout gets clogged?

Using a stiff wire to unclog a duster's spout is the recommended action because it allows for the removal of any obstructions without causing damage to the equipment. This method is effective for clearing away any pesticide residues or powder that may have hardened and blocked the spout. It's important to ensure that the duster remains functional and efficient, as a clogged spout can affect the application of pesticides and lead to inconsistent results.

Other methods, such as soaking it in water, may not address the issue effectively or could potentially harm the duster, especially if the materials used are not water-resistant. Replacing the entire duster would be unnecessary expenditure when a simple and effective solution is available. Leaving it to dry without addressing the clog would not resolve the issue, leaving the equipment unusable for its intended purpose. Therefore, using a stiff wire is the most practical and efficient approach to maintaining the equipment.
