Signs of Spoilage
Loss of spray pressure (weak or no spray), nozzle is clogged, a distinct rancid or 'off' smell (like old crayons, metallic, or bitter) when sprayed, oil appears darker or has sediment, sprayed oil feels sticky or uneven.
How to Check
-
Spray Test: Spray a small amount onto a paper towel. Check for consistent spray pressure and a fine mist.
-
Smell Test: Immediately smell the sprayed oil for any rancid, sour, or unpleasant odors. It should smell neutral or like the oil it's made from (e.g., olive, canola).
-
Visual Inspection: Observe the color and clarity of the sprayed oil on the paper towel. Check the nozzle for any clogs or residue.
-
Performance Test: If the previous tests pass, try spraying a pan – it should coat evenly and not feel sticky.
Storage Tips
Always store away from heat. Clean the nozzle with a damp cloth after each use to prevent residue buildup and clogging, which can extend the usable life of the can. While the oil inside is largely protected by the aerosol, the propellant can degrade or the nozzle mechanism can fail over time.

How to Check
Visually inspect the can for any signs of damage or compromise. Check the printed 'best by' or expiration date on the bottom or side of the can.
