If it still doesn’t spray, hold the can upside down after shaking it for a minute or so, then spray it again. The pressure buildup should release the softened matter clogging the nozzle. If it still doesn’t clear, remove the nozzle again and push a thin pin or needle into the spray hole.
How do you fix aerosol can that won’t spray?
Re: How to fix aerosol cans that won’t spray? @greeneyedgirl107- Try soaking the spray nozzle in alcohol, some hair products are laquer based which dissolves in alcohol and not particularly water soluble. Do not try to repressurize the cans or stomp on them.
