How Long Does Cooking Spray Last?
How long does cooking spray stay fresh in your pantry?
Cooking spray lasts about 12 months in the pantry if stored correctly.
Cooking spray is a convenient way to apply a light coating of oil or non-stick agents to your cookware. Because it is typically formulated with preservatives and stabilized oils, it has a relatively long shelf life compared to raw ingredients. However, environmental factors like heat, moisture, and air exposure can degrade the quality of the contents over time. When stored in a cool, dry pantry, most cans will remain effective for up to a year. If you notice changes in texture or smell, it may be time to switch to a fresh can.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does cooking spray last?
Cooking spray typically lasts about 12 months when stored in a cool, dry pantry. Proper storage helps prevent the oils from going rancid.
Can I use cooking spray if it smells slightly off?
If the smell is distinct or bitter, the oil has likely oxidized. While not necessarily dangerous, it will impart an unpleasant taste to your food.
Does heat affect the shelf life of cooking spray?
Yes. Storing cans near a stove or in a hot pantry accelerates oxidation and can degrade the chemical consistency of the aerosolized oil.
Should I store my cooking spray in the refrigerator?
No, refrigeration is not necessary for cooking spray. It is shelf-stable, but you should keep it away from direct heat sources to maintain quality.
Keep your spray in a cool, dry spot to keep that mist fresh for as long as possible!
