What should nozzle tips never be unclogged with?

Nozzle tips should never be unclogged with a piece of wire because this can potentially damage the nozzle. Using wire can scratch the internal surface or create larger openings, which can lead to uneven spray patterns or malfunctioning of the nozzle. Additionally, a wire can break off inside the nozzle, causing a more significant blockage or affecting the equipment's performance.

Proper methods for unclogging should involve safer alternatives that maintain the integrity of the nozzle, such as flushing it with water or using the manufacturer's recommended cleaning tools. Using a screwdriver or other sharp objects is also not advisable, but the specific danger with wire makes it the most inappropriate choice among the options listed.
