Can it sit out?
Cooking spray is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if cooking spray has gone bad
- A paint-like or crayon smell on the spray
- Gummy brown varnish built up around the nozzle
- Spray that spits and dribbles instead of atomizing
When in doubt, throw it out.
Store it away from the stovetop — the heat rising off the burners ages the oil inside faster than anything on a cool shelf.
