Spray bottle nozzles are designed to spray liquid in an even fashion from a bottle. Nozzles are used on hairspray, paint, leave-in conditioner and household cleaning bottles. Occasionally, residue from the liquid inside the bottle can build up on the nozzle and clog the spraying mechanism. This is especially common in hairspray bottles because the liquid being sprayed is so sticky. Instead of throwing away your clogged bottle, thoroughly clean the nozzle to remove as much residue as possible.
Remove the nozzle from the spray bottle.
Rinse the nozzle in warm water and use your finger to scrape away any visual residue or dirt.
Fill a small bowl with water and vinegar. Place the nozzle in the mixture and allow it to soak for 5 to 10 minutes.
If the nozzle remains clogged, place it in a small bowl of pure rubbing alcohol and let it soak for 5 to 10 minutes.
Rinse the nozzle in cool water and reattach it to the spray bottle.
Avoid scraping the nozzle with a pin or other metallic tool. This can permanently destroy the spraying mechanism on the nozzle. If you must use something to remove residue from the nozzle, use a toothpick, as this will cause the least amount of damage.
