How Long Does Cooking Spray Last?
Keep your kitchen surfaces and pans pristine with fresh cooking spray.
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 lasts about 12 months in the pantry if stored correctly. Maintaining a cool, dry environment helps preserve the quality of the oil.
Can I use cooking spray if it smells a bit old?
Sage's Verdict: If the smell is distinct or 'off', the oil has likely oxidized. While it won't make you sick, it will leave a bitter taste on your food.
Does heat affect the shelf life of cooking spray?
Yes, keeping the can in a hot area (like near a stove) accelerates oil oxidation and can degrade the chemical consistency of the spray.
Should I refrigerate my cooking spray?
No, it is not necessary to refrigerate cooking spray. It is shelf-stable in the pantry; however, you should keep it away from direct heat sources to prevent the oil from going rancid.
Keep your spray in a cool, dry spot to keep that mist fresh for as long as possible!
