The most common way to fix an elf setting spray nozzle is to take it apart and clean it thoroughly. Start by removing the top cap and unscrewing the pump head. Then, use a toothbrush to scrub the interior of the pump head with warm soapy water. Make sure to remove any residue that may have built up over time. Once the pump head is clean, reattach it and test it by pumping a few sprays. If it still doesn't work, you may need to replace the pump head.
