Non-aerosol citrus sprays use 100% natural citrus oils, which can occasionally clog or corrode standard spray nozzles over time if residual oil dries inside the orifice. To fix or clear the clog, submerge the removable plastic spray nozzle tip in warm, soapy water or rubbing alcohol for a few minutes and wipe clean. Holding the can upright during use also helps prevent propellant loss before the liquid empties.
